Efecto de la deforestación en la hidrología del sur y oeste de la Ciudad de México, 1973-2002.
Provedor de dados: 32
Autores: García Aguirre, María Concepción.
Los bosques ubicados al sur y oeste de la Ciudad de México son muy importantes para la recarga  de mantos acuíferos que suministran agua a los habitantes de esta ciudad, pero se encuentran  afectados por tala, incendios forestales, plagas, enfermedades y urbanización. En el presente  estudio relacioné los patrones de cobertura vegetal de la región  con otros elementos del paisaje  (geología, geomorfología, suelos, clima) y estimé el efecto de la pérdida de cobertura vegetal a  través de tiempo, sobre el patrón de escurrimiento superficial de agua en la zona,  a través de   modelado conceptual  y  cartográfico. Estimé el nivel de cambio en superficie de los bosques en  el periodo 1973-2002, utilizando imágenes de satélite Landsat (MSS y  ETM), con apoyo de...

The integration of local knowledge and science represents an opportunity to enhance the understanding of interrelations among climate, hydrology, and socioeconomic systems while providing mutual benefits to scientists and rural communities. Insight from rural Alaskans helped to identify a social-ecological threshold used to model potential driftwood harvest from the Yukon River. Information from residents of Tanana, Alaska, was combined with scientific data to model driftwood harvest rates. Modeling results estimated that between 1980 and 2010, hydrologic factors alone were responsible for a 29% decrease in the annual wood harvest, which approximately balanced a 23% reduction in wood demand because of a decline in number of households. The...

An Adaptive Environmental Assessment and Management workshop process was used to assist Grand Canyon scientists and managers in developing conceptual and simulation models for the Colorado ecosystem affected by Glen Canyon Dam. This model examines ecosystem variables and processes at multiple scales in space and time, ranging from feet and hours for benthic algal response to diurnal flow changes, to reaches and decades for sediment storage and dynamics of long-lived native fish species. Its aim is to help screen policy options ranging from changes in hourly variation in flow allowed from Glen Canyon Dam, to major structural changes for restoration of more natural temperature regimes. It appears that we can make fairly accurate predictions about some...

Does wrong procedence assignment lead to underestimates in groundwater biodiversity?
Provedor de dados: 67
Autores: Fernández,Hugo R.
Individuals of certain taxa (e.g., water mites and crustaceans) collected from streams and rivers are often assigned to a surficial benthic origin when the animals clearly display subterranean morphological characteristics. This paper addresses reasons for these errors and proposes ways to minimize such mistakes when sampling.

DAILY RAINFALL DISAGGREGATION COEFFICIENTS FOR THE DOCE RIVER BASIN, BRAZIL: REGIONAL APPLICABILITY AND THE RETURN PERIOD INFLUENCE
Provedor de dados: 70
Autores: Passos,Jéssica B. de M. C.; Silva,Demetrius D. da; Lima,Rafael P. C.
ABSTRACT Alternative methods to the intensity-duration-frequency equations have been used for intense rainfall study in places with no pluviographic data. A pioneering study, by CETESB (1986), established rainfall disaggregation coefficients for Brazil; however, the use of these coefficients take into account neither the rainfall characteristics of the interest locality nor the return period influence in obtaining the precipitation intensities. This study aimed to determine rainfall disaggregation coefficients for Doce river basin; to verify the validity of the regional coefficients use for the entire basin; and to evaluate the return period influence on these coefficients. Data from 19 gauges located in the basin, with rainfall associated with durations...

POSSIBILITIES FOR ECOHYDROLOGICAL MONITORING IN NATURAL AND MANAGED ECOSYSTEMS IN SOUTHERN CHILE
Provedor de dados: 73
Autores: Peters,Jan; Wieme,Vanessa; Boeckx,Pascal; Samson,Roeland; Godoy,Roberto; Oyarzún,Carlos; Verhoest,Niko.
Ecohydrology investigates how hydrological processes affect plant growth and vice versa. As these mutual interactions are important in many ecosystems, ecohydrology has wide applicability. An important aspect of ecohydrological research is the assessment and prediction of the occurrence of plant species or vegetation types in relation to hydrological or hydrogeochemical habitat conditions. Several models have been developed (e.g. DEMNAT, ICHORS, ITORS, ITORS-VL). All of these models are data driven. Consequently a monitoring network has to be installed, possibly in addition to existing databases. These networks are ecosystem specific but the most widely monitored variables are: water table depth, electric conductivity of groundwater, soil moisture content...

Autores: SOUZA, O. C. de; ARAÚJO, M. R.; USSAMI, N.; FISSEHA, S.; KONZEN, L.
Nas últimas décadas, grandes áreas de Cerrados de Mato Grosso do Sul foram convertidas em sistemas produtivos agrícolas e pastoris, sem a devida observância do potencial de utilização das terras. Com o tempo, algumas regiões, como a Bacia do Rio Taquari, passaram a apresentar problemas ambientais de grandes proporções em resposta a processos erosivos, cuja evolução progressiva sugere ineficiência dos sistemas de manejo visando à conservação ambiental. Os processos erosivos, estabelecidos na região de planaltos da alta Bacia do Rio Taquari, manifestam-se em escalas temporal e espacial ainda não inteiramente compreendidas e consideradas. Há falta de estudos sobre a erosão fluvial, principalmente em cabeceiras de drenagem, que acumulam grandes quantidades de...

The India-France SARAL/AltiKa mission is the first Ka-band altimetric mission dedicated primarily to oceanography. The mission objectives were firstly the observation of the oceanic mesoscales but also global and regional sea level monitoring, including the coastal zone, data assimilation, and operational oceanography. SARAL/AltiKa proved also to be a great opportunity for inland waters applications, for observing ice sheet or icebergs, as well as for geodetic investigations. The mission ended its nominal phase after three years in orbit and began a new phase (drifting orbit) in July 2016. The objective of this paper is to highlight some of the most remarkable achievements of the SARAL/AltiKa mission in terms of scientific applications. Compared to the...

Since 1987 Antifer oil tanker terminal (Normandy, France) was weIl known, as a preferential area for summer highest blooms of Dinophysis cf acuminata, a toxic dinoflagellate. Three oceanographic cruises were made in August 1989, before, in the course of and after the seasonal max. of this species. Results obtained from these cruises (hydrological parameters and phytoplankton) as weIl as from a daily survey at a reference station in Antifer harbour, corrobora te the prevailing role of coastal up flowing of Seine estuarine waters, pushed to the coast by a dominant S - SW wind, on intensity and duration of Dinophysis bloom. Such observations are in agreement with those of Summer 1987 at reference station.

Detecting hydrological landscapes over the Bay of Biscay continental shelf in spring
Provedor de dados: 5
Autores: Planque, Benjamin; Lazure, Pascal; Jegou, Anne-marie.
A complex set of hydrodynamical structures co-exist over the Bay of Biscay continental shelf. These structures, which can spread over a limited spatial range (10s of km) and last for periods ranging from days to months, influence the rates and nature of biological production. They need to be accurately described before the mechanisms linking hydrodynamics to production can be unraveled. Such description generally requires not only 3D observations of hydrological fields (temperature, salinity, density), but also a description of how these fields vary with time. This is hardly achievable with current means of field observation but can be mimicked by hydrodynamic model simulations. Using simulations from a 3D hydrodynamic model, we developed a methodology...

Autores: Beaudouin, Jacqueline.
Sampling was carried out during 1970 at 22 stations from 72 degree -62 degree N; the sampling period varied from 21 minutes - 42minutes. 12 species of zooplankton were recovered consisting of specimens of copepods, euphausiids, chaetognathes, medusae, amphipods, pteropods and decapods. They were most abundant in the central zone, especially in 2 areas of maximum concentration (where the catch exceeded 100 cm super(3)) located 72 degree N and 67 degree N. Fish captured included young cod, rockfish and halibut; they were found mostly around these areas of maximum zooplankton concentrations. Only immature fish were recovered in this region; the adults had deserted these waters due to unusual and permanent low temperature water in the superficial layers.

Modélisation stochastique des variations à court terme du niveau d'eau dans l'estuaire du Saint-Laurent, Canada
Provedor de dados: 5
Autores: Hilmi, K; Chanut, Jp; Elsabh, M.
Hourly sea level records taken at Quebec-Lauzon in the St. Lawrence estuary, Canada, are analysed both in frequency domain from 1970 to 1979 and time domain during 1973. Periodic variations, identified by spectral analysis and adjusted by harmonic regression, explain 90 to 95% of the total sea level variability. The residual (non tidal) variations of sea level, stochastic in nature, are responsible of great amplitudes of seiches and storm surges. Such series, representing less than 10%, is tested for its stationnarity and randomness and fitted by AutoRegressive-MovingAverage (ARMA) model. The long-period variations (2 to 28 days) correspond to atmospheric pressure and winds. The short-period variations (2 hours to 1 day) call be attributed to seich-like...

Four oyster rearing conditions, varying culture location ("on-" or "off-bottom"), and site depth (65% to 80% daily immersion termed "deep" or 45% to 65%, termed "shallow") were studied to compare biologic performance and maturation status of oysters, in relation to sediment and water column parameters. The most severe mortality occurred in June to July in "on-bottom" reared oysters (25%), as compared with 10% mortality in "off-bottom" cultured oysters. Oysters (shell and meat) grew significantly better when reared "off-bottom" than "on-bottom."...

This is the 36th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

A model of the general circulation in the Persian Gulf and in the Strait of Hormuz: Intraseasonal to interannual variability
Provedor de dados: 5
Autores: Pous, Stephane; Lazure, Pascal; Carton, Xavier.
Previous studies modeling the circulation and thermohaline structure in the Persian Gulf have suggested that interannual variability and vertical mixing processes could explain the model biases when compared to the few observations available. Here, a realistic, interannual, high-resolution model of the Persian Gulf is presented, validated against observations and then used to describe the intraseasonal to interannual variability in the circulation, water mass formation and exchange through the Strait of Hormuz. Sensitivity experiments to model settings, in particular vertical mixing parameterizations, have been performed in order to have the best comparison with all available observations. Main circulation and water mass characteristics correspond well to...

This report is the 18 th on annual surveillance of the nuclear plant site of Gravelines. In 1996, mean power output was 4160 MW with a cooling flow rate of 213 m3 / sec leading to an outfull vT of 9°26. The major impact of chloration is due to bromoform (18.3 ug / 1) in outflow. The amplitude of the vibrio annual cycle is stable when compared to previous years but diversity increases. In 1996, earlyness in species reproduction was noticeable. Chlorophyll biomass reached 45 mg / m3 and noctiluca cycle was quite unusual. Impact is estimated aroud 20 - 40 % in phytoplankton biomass and 30 - 100 % in zooplankton, depending on the species. Subtidal abra alba populations have been studied. For intertidal populations disappearance of spio martinensis is to be...

A monthly time-series of the seasonal evolution of the North Mediterranean Current (NMC) and of nitrogen flux across a transect (5 degrees 12'5 E between 43 degrees 10'N and 42 degrees 50'N) at the entrance of the Gulf of Lions was carried out over two years. The NMC exhibited two distinct structures: a winter structure (from November to May) characterised by strong mesoscale and interannual variations in which the current was 20 to 30 km width, about 400 m depth and velocity scaled between 5 and more than 40 cm s(-1); and a summer structure (from May to November) which was less sensitive to mesoscale variations but showing large interannual variability. The current was located more offshore, was wider and shallower than the one in winter and velocity...

Zooplankton study presented in this paper, is one of the three parts of fish ecology study undertaken by IFREMER in 1983 on Electricité de France request. The present work draws up an inventory of young stages from meroplanktonic species (fish eggs and larvae, crustacean larvae and postlarvae) in the area studied (a part of gulf of St Malo) together with rather large holoplanktonic organisms. Sampling period (from March to September) and periodicity were choosen according to study of hatching area and period of economical crustaceans. An hydrological study was carried out in the same time.

La baie de Seine : hydrologie, nutriments, chlorophille (1978-1994)
Provedor de dados: 5
Autores: Aminot, Alain; Guillaud, Jean-francois; Kerouel, Roger.
The data of hydrology, nutrients and chlorophyll obtained in the Bay of Seine over the period 1978-1994, from 14 océanographie cruises, are synthetised and illustrated by an atlas. The Bay is a typical example of a coastal area influenced by a large river. In winter, the nutrient input is drained off into the eastern Channel. In spring, nutrients are consumed intensively. Silicate is the first that drops to limiting levels. The spring bloom generally begins in the centre-east of the Bay. Chlorophyll a can reach up to 40-70 µg/l during the year, values typical of eutrophic coastal areas. Despite the regular increase of nitrogen inputs, the biomass (as chlorophyll) has not significantly changed over a fifteen year period.

This is the 39th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached a maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

Hydrology and circulation in the Strait of Hormuz and the Gulf of Oman - Results from the GOGP99 experiment: 1. Strait of Hormuz - art. no. C12037
Provedor de dados: 5
Autores: Pous, Stephane; Carton, Xavier; Lazure, Pascal.
In October and early November 1999, the GOGP99 experiment collected hydrological, currentmeter, tide recorder, thermistor and drifting buoy data near the Strait of Hormuz. Data analysis provides the water mass structure in the Strait: Persian Gulf Water (PGW) core is banked against the Omani coast, while Indian Ocean Surface Water (IOSW) lies near the Iranian coast. These water masses are most often covered by a homogeneous surface layer. Thermohaline characteristics of the PGW core decrease substantially downstream, from the Persian/Arabian Gulf to the Gulf of Oman. PGW and IOSW thermohaline characteristics and distribution also exhibit notable changes at periods shorter than a month as shown by repeated hydrological sections. The tidal signal measured...

Variabilité du panache turbide de la Gironde par télédétection. Effets des facteurs climatiques
Provedor de dados: 5
Autores: Froidefond, Jm; Jegou, Anne-marie; Hermida, J; Lazure, Pascal; Castaing, P.
The Gironde estuary (France) discharges to the ocean an important amount of suspended particulate matter in the form of turbid plumes. The surface plume is more particularly studied from coastal oceanographic surveys and NOAA/AVHRR satellite data collected during a French programme of coastal oceanography (PNOC-Atlantic). The AVHRR reflectances are atmospherically corrected according to an algorithm based on the clear water concept. The comparison with suspended sediment concentrations are realised by direct and indirect calibrations. The correlations obtained show that at a same concentration the reflectance varies, probably because of varying particle (floc) size and composition. The shape and the surface measured from low resolution (4 km x 4 km) and...

Analysis of salinity measurements near islands on the French continental shelf of the Bay of Biscay
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie; Kerdreux, Michel.
The Bay of Biscay is characterised by large fresh water inputs from two major rivers, the Loire and the Gironde, with a mean discharge of about 900 m(3)/s. To describe the spatial and temporal variability of the Loire and Gironde plumes, continuous salinity measurements were made at 4 locations on French coastal islands over periods lasting at least two years. These islands are located at a distance from the large local gradients linked to local inputs. Whereas sea surface salinity in the centre of the Bay of Biscay is 35.6, salinities at the coast vary between about 35 in summer to occasionally less than 30 in late winter or in spring. Minimum salinities do not occur at the same time along the coast, indicating a strong spatial gradient. Near the Loire...

An hydrobiological monitoring survey has been carried out in the Bay of Marennes-Oléron since 1977. Five stations, distributed over the Bay, were sam pied twice a month. Spatial and temporal trends of the physical characteristics (i.e., seawater, temperature, salinity, dissolved oxygen and suspended matter), nutrients (azote, nitrite, nitrate, silicate) and organic variables (chlorophyll a and pheopigments) were assessed by using a statistical time-series analysis mode\. It was used to distinguish seasonal variability from long term trends. Pluviometric data as weil as the Charente River fluxes were similary analyzed by the model. The seasonal variability showed an homogeneous pattern over the five stations for all parameters, but the site-dependent...

The horizontal circulation of the subpolar gyre and the Meridional Overturning Circulation (MOC) are investigated here by comparing two snapshots of the North Atlantic as delivered by two hydrographic sections between Greenland and Portugal. The corresponding cruises were carried out in June–July 2002 and June–July 2004 on R/V Thalassa within the framework of the Ovide project. The absolute transports in June 2004 are described in detail, and then compared with transports in June 2002. The MOC (in density coordinates), driven by the volume balance between the northward North Atlantic Current (NAC) and the net southward export of dense water from the subpolar gyre, did not change: View the MathML source (1 Sv=106 m3 s−1). Its upper limb, above σ1=32.1, is...

As a part of hydrological sampLing operation in South Brittany, 8 transects for 26 sampling stations were made in order to determine horizontal, and vertical distribution of Dinophysis sacculus in the 10 m layer. Un like to 1986, results do not show any correlations between Dinophysis concentrations and stability index. That may, nevertheless, be due to lower cells densities in 1987 when compared to 1986. A thermal, gradient, lower than in 1986, is still observable in the Bouthern of Loire Mouth. And, as a last point, when chlorophyll a concentrations are higher in - 10 m layer than in surface layer (Audierne and Noirmoutier areas), it can be observed hight densities of an other toxie Dinoflagellate : Gyrodinium aureolum .

The environmental impact of a brown trout farm located in the Grande Rade de Cherbourg (Normandy) is reported. During observations the fish stock evolved within the range of 140 to 350 metric tons. Farm influence was researched on water column through hydrochemistry, phytoplankton, faecal bacteria and, on bottom, through grain size, organic matter, metals, macrobenthos. This report only deals with water column.  Except ammonia, no hydrological parameter seems to be affected, even near to the net pens. Phytoplankton and coliform bacteria were not altered. An extra concentration of ammonia was detected at some tens meters from the raft, with favourable conditions. But generally it was impossible to observe it unless close to the farming structure, downward...

Autores: Alves, Jose Miguel Rodrigues; Carton, Xavier; Ambar, Isabel.
Hydrological and LADCP data from four experiments at sea (Semane 1999, 2000/1 2000/3, 2001) are used to describe the structure and circulation of Mediterranean Water in the Gulf of Cadiz. These data were gathered on meridional sections along 8?20′W and 6?15′W and between these longitudes on a zonal section along 35?50′N. The mesoscale and the submesoscale structures (Mediterranean Water Undercurrents, meddies, cyclones) observed along these sections are characterized in terms of thermohaline properties and of velocity. The transports of mass and salt in each class of density (North Atlantic Central Water, Mediterranean Water, North Atlantic Deep Water) are computed with an inverse model. The model indicates a general eastward flux in the Central Water...

Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

La dispersion des apports de la Gironde sur le plateau continental. Données in situ, satellitales et numériques
Provedor de dados: 5
Autores: Hermida, J; Lazure, Pascal; Froidefond, Jm; Jegou, Anne-marie; Castaing, P.
Coastal waters are generally a product of mixing between continental and oceanic originated water masses. Near river mouth areas, as in the Gironde estuary, oceanic waters are modified by the influence of freshwater discharge that introduces suspended and dissolved substances, including pollutants. Within PNOC (Programme National d'Oceanographie Cotiere) our objective is to determine the extent of the influence of the Gironde estuary on to the Aquitanian continental shelf. Several cruises for collecting hydrological data have been carried out in this area. The data of every cruise were coupled with a NOAA-11 satellite passage. The recorded images have been analysed and were compared with the results given by a 3D mathematical model. The interaction among...

Observations of the Ushant tidal front in September 2007
Provedor de dados: 5
Autores: Le Boyer, A.; Cambon, Gildas; Daniault, N.; Herbette, Steven; Le Cann, B.; Marie, Louis; Morin, P.
The Ushant tidal front is the dominant feature of the summer season hydrological structure of the Iroise Sea. It separates tidally mixed coastal waters from thermally stratified open Celtic Sea waters. This article reports on observations made in September 2007 during two short cruises that took place aboard R/V "Cotes de la Manche", and gives a general account of the physical structure of the front along one cross-frontal transect. The data set comprises data from a 4 month ADCP mooring, short CTD/fluorescence/nutrients transects, Lagrangian drifter trajectories, and HF radar surface current measurements. One finding is that the surface and bottom fronts, being affected by different dynamical influences, are not necessarily coincident in the vertical....

Provedor de dados: 5
Autores: Lassus, Patrick; Truquet, Philippe; Le Dean, Loic; Bardouil, Michele.
During the oceanographic cruise of June 1988, phytoplankton and correlated hydrological parameters were studied in the coastal area between Camaret and Ile d'Oléron. 62 stations were sampled in the 0-30 m layer within the 50 m depth limited coastal area. Observations focused on two toxic dinoflagellate species: Dinophysis spp and Gyrodinium aureolum. Dinophysis spp is more abundant in the Loire/Vilaine area, which is.characterized by high surface Nitrate levels, high 30 m depth Phosphate levels and Chlorophyll a amounts higher than elsewhere during the survey. This particuliar pattern can be related to the Nutrient outputs of Loire and Vilaine Rivers. Max. Dinophysis concentrations were observed in Vilaine bay (very high Phosphate levels) and in Douarnenez...

L'oued Tinja relie la garaet Ichkeul à la lagune de Bizerte laquelle communique avec la mer Méditerranée par un long goulet. Les eaux de cet oued dépendent à la fois des apports saisonniers des eaux marine et douce et présente de ce fait, des salinités très fluctuantes. L'important réseau hydrographique associé au plan d'eau de l'Ichkeul (avec un bassin versant très important d'environ 2080 km2) est sujet à de nombreux aménagements hydrauliques, notamment la construction de barrages de retenues d'eau douce. Ces derniers sont susceptibles de perturber les caractéristiques hydrologiques, sédimentologiques et géochimiques du système laguno-lacustre (lagune de Bizerte et garaet Ichkeul) et d'entamer par voie de conséquence sa diversité et sa richesse...

La réouverture artificielle du canal naturel du fleuve Comoé (22 septembre 1987)en vue de l'élimination en mer des plantes flottantes envahissantes, a modifié considérablement l'environnement hydro-sédimentaire du domaine lagunaire à Grand-Bassam. L'action des courants de marée a conféré un caractère plus estuarien aux eaux lagunaires, l'intrusion saline (25-30%0)remontant au delà des ponts de Moossou à la confluence du fleuve Comoé. Ceci a entraîné un curage du cours inférieur du fleuve et surtout des fonds lagunaires antérieurement confinés. La remobilisation des vases (des fonds autour de l'île Bouët), évacuées en suspension vers le large a découvert les faciès sableux lagunaires et marins. Ce nouveau système demeure fragile, par la suite d'un colmatage...

Autores: Ramírez-T., G.
Se estudiaron las condiciones fisicoquímicas de la Bahía de Santa Marta, Litoral Caribe colombiano, desde agosto de 1980 hasta julio 1981. La similitud de los resultados obtenidos en nueve estaciones indican que las aguas superficiales son homogéneas y de características oceánicas. De diciembre a abril se registran las temperaturas más bajas (&lt; 25°C) asociadas a altas salinidades (&gt;36o/oo) y subsaturaciones de oxígeno disuelto (&lt; 91o/o): estos factores, conjuntamente con observaciones de pH, alcalinidad y la variación de la estabilidad de la columna de agua evidencian procesos de surgencia en este período, permitiendo establecer un modelo aproximado para el ciclo anual de la bahía.

Modelling the influence of ecological interactions on reactive transport processes in sediments
Provedor de dados: 27
Autores: Meysman, F.
Within the natural sciences, it has long been recognized that biological activity can modify the texture, structure and composition of surface sediments. Darwin (1881) already examined the stirring of soils by burrowing earthworms and made detailed observations on how these organisms affect soil processes. A similar phenomenon can be observed in aquatic sediments, which are inhabited by a diverse biological community, supported by the flux of organic matter and oxygen from the overlying water column. Surface sediments of oceans, estuaries, lakes and rivers are highly active biogeochemical environments and an effective way to generate insight in the complexity of the interactions is by means of so-called general early diagenetic models (e.g. Soetaert et al,...

Estimating productivity of water at different spatial scales using simulation modeling
Provedor de dados: 31
Autores: Droogers,   Peter; Kite,   Geoff.
A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

The report examines the relationships between agricultural policies in the North China Plain, the approaches to water management that evolved from them, the quantity of water that was actually used, and the consequent groundwater depletion beneath Luancheng County, Hebei Province, from 1949 to 2000. To systematically address these relationships, we use a comprehensive water-balance approach. Our results indicate that a single, longstanding policy-that of using groundwater to meet the crop-water requirements not supplied by precipitation-is responsible for the steady rate of groundwater decline.

What are the Economic Health Costs of Non-Action in Controlling Toxic Water Pollution?
Provedor de dados: 31
Autores: Easter,   K. William; Konishi,   Yoshifumi; Raggi,   Meri; Viaggi,   Davide.
This paper identifies information that may be important in determining the benefits of preventing toxic water contamination (or equivalently cost of nonaction) when a given toxification occurs. It attempts to identify information and behavior issues that need to be considered when we estimate benefits and weigh them against the costs of removing toxins. This paper also provides “scenarios” for three toxic pollutants that are found in water bodies. We make use of two alternatives--one for developing countries and the other for developed countries--to demonstrate, with specific examples of arsenic, mercury and Atrazine, how benefit estimates and control policies vary with different assumptions concerning behavior/information and type of chemical...

Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia
Provedor de dados: 31
Autores: Kim,   Ungtae; Kaluarachchi,   Jagath J.; Smakhtin,   Vladimir U.
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

The challenges of integrated river basin management in India: issues in transferring successful river basin management models to the developing world
Provedor de dados: 31
Autores: International Water Management Institute,   IWMI-TATA Water Policy Program.
The problems that river basin institutions in the developed world successfully address—such as pollution, sediment buildup in rivers and the degradation of wetlands—are not the top priorities for Indian policy makers and people. The items that do top Indian agendas—providing access to water for drinking and growing food, eradicating poverty, and stopping groundwater overexploitation—are either unresolved in the developed world or have become irrelevant due to economic development. This does not mean that India and other developing countries cannot learn valuable lessons from models for Integrated River Basin Management. Loosely structured River Basin Organizations, such as Southeast Asia’s Mekong Commission, can contribute to basin welfare by serving as a...

CLIMATE CHANGE SENSITIVITY ASSESSMENT ON UPPER MISSISSIPPI RIVER BASIN STREAMFLOWS USING SWAT
Provedor de dados: 31
Autores: Jha,   Manoj K.; Arnold,   Jeffrey G.; Gassman,   Philip W.; Gu,   Roy.
The Soil and Water Assessment Tool (SWAT) model was used to assess the impacts of potential future climate change on the hydrology of the Upper Mississippi River Basin (UMRB). Calibration and validation of SWAT were performed on a monthly basis for 1968-87 and 1988-97, respectively; R2 and Nash-Sutcliffe simulation efficiency (E) values computed for the monthly comparisons were 0.74 and 0.65 for the calibration period and 0.81 and 0.75 for the validation period. The impacts of eight 20-year (1971-90) scenarios were then analyzed, relative to a scenario baseline. A doubling of atmospheric CO2 concentrations was predicted to result in an average annual flow increase of 35 percent. An average annual flow decrease of 15 percent was estimated for a constant...

Mapping drought patterns and impacts: a global perspective
Provedor de dados: 31
Autores: Eriyagama,   Nishadi; Smakhtin,   Vladimir U.; Gamage,   Nilantha.
The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.

This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and...

Explaining farmers’ monitoring of sustainability indicators: a bore-ing example for salinity in Western Australia
Provedor de dados: 31
Autores: Marsh,   Sally P.; Burton,   Michael P.; Pannell,   David J.
Dryland salinity is one of the most pressing land management problems in Western Australia. A number of projects are in progress to provide a more comprehensive picture of the location and extent of potentially saline areas in the landscape. Associated with some of these projects, a large number of bores (piezometers) have been installed or are being installed throughout the agricultural area to provide information on depth to groundwater and changes in water levels over time. These bores provide information about whether and when the ground water will reach the surface, causing losses of agricultural production through salinisation of soils. Using data from the Jerramungup Land Conservation District (LCD) we explore factors influencing the behaviour of...

ABSTRACT A study was carried out in the sub-basin of the River Cobras with the aim of evaluating the morphometric characteristics and longitudinal profile of the river basin as a tool for planning the location of underground dams. Morphometric parameters - compactness coefficient, form factor, drainage density and circularity index - were determined. An equilibrium profile was also performed in order to understand the dynamics of erosion and disposition in the sub-basin under study. The results showed that the River Cobras sub-basin is strongly elongated, with low drainage density and high rates of runoff in alluvial areas. The equilibrium profile indicated that the middle course (18 km, stretch 2) of the sub-basin includes a first-order anomaly and is...

Gravity Recovery and Climate Experiment (GRACE) mission is dedicated to measuring temporal variations of the Earth's gravity field. In this study, the Stokes coefficients made available by Groupe de Recherche en Géodésie Spatiale (GRGS) at a 10-day interval were converted into equivalent water height (EWH) for a ~4-year period in the Amazon basin (from July-2002 to May-2006). The seasonal amplitudes of EWH signal are the largest on the surface of Earth and reach ~ 1250mm at that basin's center. Error budget represents ~130 mm of EWH, including formal errors on Stokes coefficient, leakage errors (12 ~ 21 mm) and spectrum truncation (10 ~ 15 mm). Comparison between in situ river level time series measured at 233 ground-based hydrometric stations (HS) in the...

One of the appropriate strategies to evaluate watershed health is by determining peak discharge. This is associated with the influence of frequent floods and landslides on the changes in the carrying capacity of Gumbasa watershed. It was also attached to the accelerated forest and land degradation due to encroachment, especially in the upstream. This study aims to determine the estimated peak discharge of three sub-watersheds, including Lindu, Palolo, and Gumbasa to monitor and evaluate the performance of the main watershed. This was conducted using a rational method with a combined and average flow coefficient approach, while the rainfall intensity was calculated based on the longest concentration time.

Autores: Mello,Carlos Rogério de; Curi,Nilton.
Pedology consists of a sub-area of Soil Science that studies the soil and its origin as well as its inter-relationship with the landscape. Hydrology is the science that studies the water in nature in its different mediums (atmosphere, soil and rock), using the watershed as a reference for analysis of the water dynamics and also its interaction with the landscape. The relationship between these two branches of knowledge has been the object of debate and analysis in recent years, contributing to the creation of a multidisciplinary science, which seeks to integrate the respective fields of research. As such, for Hydrology, Pedology has been fundamental for enabling a foundation for the processes associated to the generation of runoff and groundwater recharge,...
