The Atlas Mountains serve as vital catchment areas that capture significant precipitation, allowing for the development of water management infrastructure. Since the 1930s, the construction of reservoir dams across the region's watercourses has been essential for modern development.12

These dams support agriculture and energy needs in the following ways:

Irrigation: The dams allow for the storage of vast quantities of water, which is then used to irrigate downstream plains, transforming the potential of mountain wadis into productive agricultural land.2
Electricity Generation: By funneling water at high pressure, these dams power turbines that drive generators to produce hydroelectric energy.23

In Morocco, major projects include dams on the High Atlas northern slopes, such as the Wadi el-Abid and Wadi el-Rhira, as well as on southern watercourses like the Drâa and Ziz rivers. Similarly, Algeria has developed hydroelectric stations in the Kabylie region on the Agrioun and Djendjene wadis. While these systems provide renewable energy, they also fundamentally alter natural river systems.23
