Simulation des écoulements mensuels par le modele GR2M Cas du bassin de l'isser.

Abstract

For a better understanding of the hydrological behavior of the Isser watershed, we have attempted to apply rainfall-flow modeling using a global reservoir model: the "GR2M" rural engineering model. Global hydrological models allow the transformation of rainfall into flow through reservoirs simulating the hydrological cycle. In recent years, these models have been applied in the field of forecasting and management of water resources. This work is based on month-scale rain-flow modeling; Is applied to the Isser catchment. The simulation results showed quite high performances for the Isser basin and can be used in other watersheds for better management of water resources.
