This volume offers a comprehensive analysis of the water resources in the Souss-Massa river basin in southwestern Morocco and provides novel water-management approaches to narrow the gap between supply and demand for water. It evaluates conventional water resources-surface water and groundwater-and discusses in detail rainfall harvesting into dams along the Souss and Massa wadis. Further, it explores topics including the geology of the aquifer; the risk of over exploitation; alternative water resources, such as desalinated seawater and treated domestic wastewater, as well as management approaches like Data Development Analysis and the SALTMED model. With a focus on linking scientific research to practical applications and the demands of agriculture and associated agro-industry, urbanization and tourism, which compete for the limited water resources, the book appeals to environmental scientists, geologists, engineers and environmental managers.
