Modeling in Hydrology

The modeling strategy of the PHyREV team aims at proposing, in one hand, tools to transpose observed local processes to the regional scale and, on the other hand, tools to be able to simulate the interactions between the different reservoirs of the Critical Zone. This strategy includes integrated modeling approaches with the Parflow / CLM model developped at The Colorado School of Mines by R. Maxwell, and simplified modeling approaches to represent only the prevailing physical process(es).

SMOS Assimilation in DHSVM: The Oueme Supérieur case study

Vignette une

The impact of the assimilation of surface soil moisture on the simulations of the physically based hydrological model DHSVM (Distributed Hydrology Soil Vegetation Model) is investigated in this paper for a 12,000 km2 catchment located in Benin, West Africa. Thanks to a large number of rain gauges spread all over the entire basin, reference simulations are performed from one year of (...)

Modélisation hydrologique des bas-fond

Vignette une

En Afrique de l’Ouest, les Bas-fonds, sont des dépressions qui restent gorgées d’eau. Ils couvrent 22-52Mha (Andriesse, Fresco et al. 1994) sur l’ensemble du continent. Situées à l’amont des cours d’eau ils débordent pendant la saison humide et constituent une source importante pour la génération des écoulements. Ils jouent ainsi un rôle majeur dans le cycle hydrologique et leur compréhension est (...)
