Geometric Drawing Model of Shape of Water Sections for the Investigation of Solid Flow Transport in the Basin of Mono River in Republic of Benin

The hydrologic and hydraulic changings on the behavior of Mono river are result stress involved by human activities, one hand construction dam Nangbéto exploitation sand in downstream population, between Athiémé Agbanankin other hand. That effect had also affected shape sections context climate variability. It shows consequently that area is a trapping sediments eroded responsible for river. slope flow rate main factors real capacity transport watercourse. They determine solid flows from upstream to downstream. This drawing model established taking into account bathymetry transversal section at Athiémé, first step global investigation basin boundary condition characterization its hydro-sedimentary dynamics study. aims take used technique which consist measure located as representative moving boat bathymetry.
