An improved model for the evaluation of groundwater recharge based on the concept of conservative use potential: a study in the river Pandeiros Watershed, Minas Gerais, Brazil. Repositório Alice
TENENWURCEL, M. A.; MOURA, M. S. de; COSTA, A. M. da; MOTA, P. K.; VIANA, J. H. M.; FERNANDES, L. F. S.; PACHECO, F. A. L..
Water resources have been increasingly impacted due to the growth of water demand associated with environmental degradation. In this context, the mapping of groundwater recharge potential has become attractive to water managers as it can be used to direct public policies and conserve this natural asset. The present study modi?es (improves) a spatially explicit model to determine groundwater recharge potential at the catchment scale, testing it in the Pandeiros River basin located in the state of Minas Gerais, Brazil. The model is generally based on the water balance approach and the input variables were compiled from institutional sources and processed in a Geographic Information System. The novelty brought by the aforementioned modi?cation relates to the...

Flood vulnerability, environmental land use conflicts, and conservation of soil and water: a study in the Batatais SP municipality, Brazil. Repositório Alice
CALDAS, A. M.; PISSARA, T. C. T.; COSTA, R. C. A.; ROLIM NETO, F. C.; ZANATA, M.; PARAHYBA, R. da B. V.; FERNANDES, L. F. S.; PACHECO, F. A. L..
In many regions across the planet, flood events are now more frequent and intense because of climate change and improper land use, resulting in risks to the population. However, the procedures to accurately determine the areas at risk in regions influenced by inadequate land uses are still inefficient. In rural watersheds, inadequate uses occur when actual uses deviate from land capability, and are termed environmental land use conflicts. To overcome the difficulty to evaluate flood vulnerability under these settings, in this study a method was developed to delineate flood vulnerability areas in a land use conflict landscape: the Batatais municipality, located in the State of São Paulo, Brazil. The method and its implementation resorted to remote sensed...

Groundwater recharge potential for sustainable water use in urban areas of the Jequitiba River basin, Brazil. Repositório Alice
COSTA, A. M. da; SALIS, H. H. C. de; VIANA, J. H. M.; PACHECO, F. A. L..
The zoning of groundwater recharge potential would be attractive for water managers, but is lacking in many regions around the planet, including in the Jequitiba River basin, Minas Gerais, Brazil. In this study, a physically based spatially distributed method to evaluate groundwater recharge potential at catchment scale was developed and tested in the aforementioned Jequitiba River basin. The data for the test was compiled from institutional sources and implemented in a Geographic Information System. It comprised meteorological, hydrometric, relief, land use, and soil data. The average results resembled the annual recharge calculated by a hydrograph method, which worked as validation method. The spatial variation of recharge highlighted the predominant...

Hydrologic modeling for sustainable water resources management in urbanized Karst areas. Repositório Alice
SALIS, H. H. C. de; COSTA, A. M. da; VIANA, J. H. M.; SCHULER, M. A.; KÜNNE, A.; FERNANDES, L. F. S.; PACHECO, F. A. L..
The potential of karst aquifers as a drinking water resource is substantial because of their large storage capacity gained in the course of carbonate dissolution. Carbonate dissolution and consequent development of preferential paths are also the reasons for the complex behavior of these aquifers as regards surface and underground flow. Hydrological modeling is therefore of paramount importance for an adequate assessment of flow components in catchments shaped on karsts. The cross tabulation of such components with geology, soils, and land use data in Geographic Information Systems helps decision makers to set up sustainable groundwater abstractions and allocate areas for storage of quality surface water, in the context of conjunctive water resources...

Water security assessment of groundwater quality in an anthropized rural area from the Atlantic Forest Biome in Brazil. Repositório Alice
VIEIRA, I. F. B.; ROLIM NETO, F. C.; CARVALHO, M. N.; CALDAS, A. M.; COSTA, R. C. A.; SILVA, K. S. da; PARAHYBA, R. da B. V.; PACHECO, F. A. L.; FERNANDES, L. F. S.; PISSARRA, T. C. T.
The exploitation of natural resources has grown mainly due to the high rate of population growth that changed over time around the planet. Water is one of the most needed resources essential for survival. Despite all the efforts made to improve water security, an environmental impact related to anthropogenic influence remains of great concern, which is the alteration of surface and groundwater quality. In many regions around the world, there is limited or no access to rural and urban water supply while there is a need to improve sanitation facilities. This work evaluated the spatial distribution of groundwater and surface water quality as well as their changes in wet and dry seasons of the tropical climate in the Atlantic Forest Biome. The study area is...
