L'utilisation des SIG dans la modélisation en hydrologie de surface

B. Abednego, R. Caloz, and C. Collet

Abstract. From a methodological point of view, hydrological modelling appears to offer a great potential for spatial analysis. However among classes of models, only physical models consider the spatial dimension as a variable. The topography and the land cover are the two major spatial components involved in that type of models. The production of a relevant DTM requires the use of iterative interpolation procedures. Land cover and its changes can be monitored and entered into modelling from remote sensing images through a normalized Vegetation index. The GIS approach can be integrated at different levels within hydrological modelling, with object oriented GIS seen as the highest level.
