Hydrogeological characterization and artificial recharge of the Tinejdad palm groove aquifer (South-East Morocco)

Résumé

The Tinjdad palm grove aquifer, located in South-East Morocco, is experiencing a recrudescence of pumping and a decrease in rainfall. The experiments carried out on the hydrological regime of the wadis showed the interest of the establishment of prohibition and safeguarding perimeters of khettaras and the artificial recharge of the aquifer by the installation of systems allowing infiltration in the wadi beds. The most suitable technique for flood waters is the setting up of dams in the wadis to artificially increase the contact area by making “dead arms” work and decrease the flow velocities downstream of the dam, while preserving groundwater resources by groundwater contracts setup and delimiting the prohibition and safeguarding perimeters.
