Représentation du couvert forestier dans la modélisation hydrologique : comparaison de dix modèles (synthèse bibliographique)

Abstract

Forest cover representation in hydrological modeling: a comparison of ten models. A review. There are many hydrological models, some of which can be used for forested environments. This review aims to compare ten of these models (BILJOU, EPIC, BROOK90, SWAT, RHESSys, MIKE SHE, SHETRAN, WaSiM ETH, DHSVM and Hydrus) in order to provide guidance in the choice of model. The comparison of the models focuses on the following forest fluxes: interception, transpiration and root water uptake, root distribution, the understory effect, tree growth and model validation. The review underlines the fact that each model deals with forest fluxes in a different way. Most of the models deal with interception in a similar way, and root distribution is used in the process of root water uptake. Understory and growth are seldom considered.
