Modélisation hydrodynamique couplée 1D-2D du delta intérieur du fleuve Niger

Abstract : The inner delta of Niger river is a large floodplain of about 30000 km2. The annual flood plays a crucial part for the agricultural activities in the region. Understanding hydrodynamic processes in the delta is essential to predict the environmental, agricultural and economic consequences of anthropogenic and climatic changes in the area. A hydraulic 1D-2D coupling model is developed to predict the spatial distribution of floods based as a function of hydrological characteristics of the year. The model is based on topographic surveys for the riverbed and satellite topographical data for the floodplain. Such a model has been built upstream from Mopti. Results have been obtained in another region, downstream from the Debo lake. They underestimate the overflow, and are to be improved, and are to be completed in the other parts of the delta.
