C.O.M.O.D. : Logiciel de choix de modèles d'ondes diffusantes et de leurs caractéristiques
COMOD : Selector software for diffusing wave models and their characteristics
Laboratoire d'hydrologie mathématique, USTL
Generally, the flood routing in rivers has the characteristic of a diffusing wave (negligible acceleration terms in Saint-Venant's equations). Many methods exist to solve these equations. The choice of a method, time and space steps to be retained depend in many factors : the form of the upstream flood, the complexity of the hydrographical network, the structures of river ponds, the location of measurement stations and the recording step. The optimized choice interactive program concerning the diffusing wave method (COMOD) guides the user in his choices and specifies the error introduced by the retained computation algorithm.
