Abstract

In this paper experimental results of ID Dam-Break flows are compared with those obtained by means of a mathematical model based on the MacCormack shock-capturing scheme. Care has been devoted to the treatment of the source terms of the equations and to the resolution of shocks. To verify the numerical model under severe test conditions, laboratory experiments have been carried out in which shock formation, reverse flow and wetting and drying conditions in the flow field were induced. Comparison of experimental and numerical results shows a very good agreement, as a whole. The essential validity of the numerical model is then confirmed, even in situations in which St. Venant hypothesis are not completely verified. Introduction Floods
