ON A MATHEMATICAL INVESTIGATION OF A SEDIMENTATION MODEL OF LAKES

Abstract

Abstract: The study of the influence of sediments brought on the sedimentary bottom formation and evolution of rivers or lakes presents a big scientific interest both by its interdisciplinary aspect and by its importance. In this work, we propose to associate the hydrodynamic and geological points with a view to establish a continuous model of the sedimentary bottom evolution processes based on conservation mass law. This model, general and progressive, make it possible to consider the flocculation phenomenon, geological activities of the bottom, and other. We establish later on the conditions of existence of admissible solutions where sedimentation is more important than the erosion process
