Coupling Physical and Numerical Models: Example of the Taoussa Project (Mali)
Fhysical modeling and numerical modeling are two efficient analysis approaches in hydraulic engineering. The interactive application of both methods is obviously the more effective response to most flow problems analyses. Indeed, it enables combining the inherent advantages of both approaches, which are complementary, while being beneficial to the delays as well as the quality of the analysis. This paper presents the results of a successful application of such a combined numerical -physical study carried out by the Laboratory of Engineering Hydraulics of the University of Liege on behalf of Coyne et Bellier (Tractebel Engineering). It concerned, at the stage of detailed draft, the hydraulic study of the Taoussa Project on the Niger River in Mali. This project accounts for a 1. 3km long embankment dam, a ship lock, a hydroelectric power plant and a gated spillway (10 gates) with a downstream stilling basin. The studies, performed in less than 6 months, focused on the flow characteristics at the scale of the reservoir and the river, using the numerical approach, as well as on hydrody-namic details in the spillway using a large scale factor physical model with boundary conditions defined on the basis of numerical modeling.
