This phenomenon is increasing in recent years, it becomes necessary to provide an effective management of the river. In this context, several axes are developed: the detailed description of area to understand the generation of flow and transfer to the outlet, the analysis of maximum daily precipitation and determining flow of the hundred-year flood map by hydraulic modelling of rivers, a description of development alternatives to choose the most suitable variant from a technical and economic point of view. Finally, we determine the duration and the cost of this project.
