It is also necessary to the development of agriculture, especially for its abundance and its impact on the economy of the country, providing different and multiple jobs and improving living conditions of rural populations. After taking all these in account, and through our graduation project, we will conduct a study on the design and execution of a dam on wadi of Merzouga (W.Tiaret ) from technical and economic point of view for irrigation of a perimeter of 70 ha. For this, we study the topography geology, hydrology and the study variants in order to repair the choice of the dam to design. Next, it is about a 11 height dam, making it possible to ensure a volume usable of 180 000 m3 of water
