Utilisation d'indicateurs de l'état hydrique du sol dans un modèle pluie-débit

Use of ground hydrous state indicators in a rain-flowrate model

CEMAGREF, Antony

Abstract

Researches concerning taking into account direct measures concerning the ground hydrous state in the flowrate forecast models have been carried out following a statistical study which demonstrated the full power of ground humidity as regards the yield function.This article covers the results obtained by means of a conceptual model with tanks simulating a continuous chronicle of an end time step flow and by measuring the benefit acquired by introducing humidity or potential data in the place of evaporation.
