Análisis comparativo en la reducción del gasto de filtración y el gradiente hidráulico entre las pantallas contra filtración y la geomembrana en presas de tierra homogénea

Abstract

The program for Water management and soil (PROMAS),that makes the PACALORI project has main purpose in the flood control and water supply for irrigation in the province of Los Ríos ,so large hydraulic infrastructure to store water during the winter and use it during the summer will be built. The main purpose of this thesis is to analyze the reduction of the seepage flow and hydraulic gradient in homogeneous earth dam of the PACALORI project for various cases of action against seepage through simulation with Geostudio(SEEP/W) software , namely in order to compare with the ecological flows established during the feasibility stage and decide whether or not action is required against filtration. In the different cases analyzed was determined that the contribution of seepage flow to ecological flow, It's negligible. For this reason, in this analysis it was concluded that no action are required against seepage, however , by international experience in earth dams, is recommended build a clay cutoff.
