Revue bibliographique : la prise en compte des transferts horizontaux dans les modèles hydrologiques

Abstract

Modelling of interflows in soils: a review. This review sums up the different schemes in hydrological modelling. Moreover, it underlines how the interflows are taken into account and draws the first lines to improve their physically based representation. In the mood of the change in agricultural practices, especially concerning the conventional tillage reduction in support of conservational tillage, it seems to be necessary to propose a better description of decisive parameters like horizontal hydraulic conductivity. More precisely, the dependence of this parameter with the water retention curve has to be described in order to represent fluxes at the plot scale and at the watershed scale. Under these circumstances, an approach with in situ measurements and physically based modelling is suggested.
