During this study, we have been introduced to TELEMAC and the different softwares linked: MATISSE to generate the geometry and the mesh and RUBENS to visualized results. This first approach of TELEMAC was very interesting because this software is one of the most used in France to solve free surface flow problem. Moreover the case we have studied was interesting although we have spend more time in running TELEMAC than in analysing our results.
        However, our tests on the confluence of two rivers with a flood or not seems to have generate quite good results. In fact, TELEMAC seems to be a good solver to analyse such problems and to simulate flood. We should have better results by running our tests anymore time or by refining the mesh. But this last possibity increase the running time.
