Modèles de crues et petits bassins versants au Sahel

Flood modelling on small watersheds in the Sahel

ORSTOM

Abstract

The Sahel is very well suited to the application of the unit hydrograph technique; several models based on this technique are thus selected. They differentiate from another by the analytical expression of the production function and by the identification algorithms of the linear response function. These models are applied to the modelling of eight small watersheds, the surface of which is less than 100 km². This work allows for a validity study of the various models for flood prediction.
