Abstract. Rain produces both, surface run off and base flow.In this journal, we will be discussing about developing a software for surface run off modelling based on the Saint Venant equation, using MacCormack 2D methode. The software calculates surface run off over time for 5 differents ground surface profiles, flat, triangular, parabolic and 2 nature profiles. Solution by numerical and analitical are compared for the flat profile. The result shows no significant different for the two methode.

Keywords: finite difference; MacCormack; modeling; numeric; run off; St.Venant.
