Etude Expérimentale Du Processus De Ruissellement Sous Pluies Simulées

The main objective of this work is to improve understanding of the hydrological functioning of catchment basin. To achieve this objective this study is built primarily on observation and measurement in side of an artificial basin to control the generation of floods by hydrological phenomen. The experimental device used is a hydrologic test bench in the laboratory of department of hydraulics, as a model of the hydrological system with a rainfall simulator . Tests were performed on a medium equivalent to silty sand. This work has been identified the influence of various parameters on the basin's hydrologic response. In the context of comparing the tests realized we tried to study the role of each individual parameter the antecedent soil moisture, slope, rainfall intensity and vegetation cover. We also highlight in the case of this study, the graphical separating hydrographs resulting of the tests realized
