Contribution à l'étude de la propagation de crues en hydrologie

Abstract : Flood routing studies are rather intricate and cumbersome due to various hydrologie and hydraulic data required and computing involved in numerical solving of the Saint Venant's equations. Therefore, it is useful, especifically in the field of Hydrology, to have simple and reliable methods for handling this phenomenon. In this work, we searched for a lumped view upon the phenomenon, through the approximative knowledge of the influence of a few parameters related both to the rivers reaches and the floods. Using these parameters in simplified routing modelling was the aim of this thesis. First, from the linear diffusive model outlined by Hayami, and after some simplifications about the shape of hydrographs, one could propose a method to assessing flood peaks routing. Then, one worked in the more comprehensive frame of the Saint Venant model, and from an a posteriori analysis of the outcome of various flood routing simulations according this model, one proposed simplified routing models, applicable to the flood peaks. Finally, we examine the feasability of these models on actual river reaches and floods.
