Ecriture d'un code C++ pour la simulation en hydrologie

Abstract : Shallow water system is a typical model for the simulation of overland flow. We had a 1d fortran program to simulate one dimension flow, based on a well-balanced method. This code was validated on several analytical and experimental test cases. Nevertheless, this code was ill-structured and did not allow for the development of modules. As such this code became difficult to develop further. During this internship, we developed a c++ code for overland flow. First developed in one dimension, with then develop a code simulating the overland flow over a surface. An analysis of the mathematical model allowed us to point out the programming constraints that we will have to face. Simulations based on the c++ 1d program were compared with the simulations of the fortran program. Some differences in the results remaind to be explained before the c++ 1d code could be considered as validated. The changes carried out on the c++ 1d code will be directly implemented into the c++ 2d code.
