Hydrological Regime Alteration in the Lower Ouerrha River Basin Following the Construction of Al Wahda Dam

Abstract

The Al Wahda Dam is a major hydraulic structure in the integrated management of water resources in Morocco. Its commissioning has significantly improved flow regulation, secured the water supply for irrigation and human consumption, and guaranteed minimum flows during periods of drought. It also plays a key role in mitigating flood risks and supporting agricultural and socio-economic development in the affected areas.

Through this study, we analyse the extent of the Al Wahda Dam’s hydrological impact on its environment, highlighting the changes it has brought about in the hydrological functioning of the Ouergha catchment and, more broadly, the Sebou catchment. The results show that this structure contributes to better mobilisation and utilisation of water resources, whilst strengthening the region’s resilience to climate variability and extreme hydrological events. This research thus highlights the strategic role of the Al Wahda Dam in promoting sustainable water resource management and in strengthening water and food security at regional and national levels.
