Modelación hidrológica y análisis de factibilidad técnica y económica del proyecto de temporal tecnificado de ampliación del Bajo Papaloapan-Tesechoacán, estado de Veracruz. Colegio de Postgraduados
Rodríguez Rodríguez, Jesús.
Se realizó la modelación hidrológica y el análisis de factibilidad técnica y económica del proyecto de ampliación de la superficie del Distrito de Temporal Tecnificado 003 Tesechoacán, cuenca del río Papaloapan, que presenta problemas con inundaciones. A partir de la información de los estudios básicos, se realizó una simulación hidrológica usando el software MIKE, del Instituto Hidráulico Danés, para identificar las áreas de afectación. La modelación realizada permitió precisar las superficies inundadas las cuales, al estar georreferenciadas, permitieron el análisis de diferentes estrategias de control de inundaciones. Considerando un periodo de retorno de 25 años, el área inundable simulada bajo las condiciones actuales resultó de 51,175.59 ha. Se...

IMPLICATIONS FOR PEAK FLOWS OF THE MARRECAS RIVER BASIN DUE TO CHANGES IN THE BRAZILIAN FOREST CODE REA
Aguiar,Wagner de; Sampaio,Silvio C.; Paisani,Julio C.; Reis,Ralpho R. dos.
ABSTRACT Changes in the Brazilian Forest Code (BFC) have soften the criteria for recovery and conservation of permanent preservation areas (PPAs), enhancing processes related to surface runoff. The aim of this study is to understand the effects of changes in PPA classification criteria established by BFC of 2012 to the detriment of BFC from 1965 considering the surface runoff response in the basin draining the upper Marrecas River valley in the flow peaks. The HEC–HMS model was used to simulate flow peaks considering three land-use scenarios, representative of the current use, adapting it to PPAs fitted to the BFC of 1965 and 2012 and seven precipitation return periods. In the proposed scenarios, the use of BFC of 2012, to the detriment of that from 1965,...

SEASONAL DYNAMICS OF AGRICULTURAL SOIL COVER IN RUNOFF GENERATION REA
Aguiar,Wagner de; Sampaio,Silvio C.; Paisani,Julio C.; Remor,Marcelo B.; Reis,Ralpho R. dos.
ABSTRACT Seasonal changes in agricultural soil use due to agroclimatic conditions affect the water cycle in watersheds. This study aimed to understand the temporal variation of runoff inherent to the seasonal occupation dynamics of the agricultural soil in the basin that drains the upper valley of the Marrecas River, upstream of the urban perimeter of Francisco Beltrão, PR. The effects of runoff were verified through flow peaks simulated by the HEC-HMS model in twelve monthly soil use scenarios, under seven precipitation return periods. The results indicated a strong relationship between bare soil and flow peaks, temporally delimiting April and March as the largest runoff generators and January and August as the smallest ones. The ratio quantified by rates...
