Modélisation de la dynamique potentielle d’un bassin versant et mesure de son efficacité structurelle

Classical morphometric indexes have been the first quantitative methods created by geomorphologists to compare the morphometric characteristics of many catchments and to quantify their theoretical hydrologic behavior. Even if many indices still remain quoted in numerous hydrologic books, a few autho...
