| Résumé: | This study is concerned with the management of water resources and development of a DSS
(Decision Support System) in MMS (Modular Modelling System) for the semi-arid, mountainous Drâa
catchment in SE Morocco. The catchment relies heavily on oasis irrigation in three different geographical
units. These include firstly, the High Atlas mountains, secondly, the basin of Ouarzazate above the Mansour
Eddahbi dam reservoir and thirdly the ancient date palmeries below the reservoir. In 1972 the dam was put
into operation for hydroelectricity and irrigation. Following decades of drought the dam’s main function
nowadays is irrigation. A DSS requires an efficient hydro-meteorological monitoring system including the
infill levels of the reservoir and the water use upstream of the reservoir. It also involves close collaborative
feedback between the developers and the water planning authorities and local end-users. In the mountains
surface water is still more or less an unlimited resource but in the forelands it is very limited for irrigation.
Uncontrolled spread of mechanised pumping is seriously straining the groundwater resources. In terms of
potential end-users, farmers in the mountain areas will be unable to implement a DSS due to high illiteracy.
However, the interest will be high for centralized agricultural and regional hydrological organisations
involved in water planning such as the ORMVAO (Organisation pour la Mise en Valeur Agricol de
Ouarzazate), farming organisations and the ABH (Agence du Bassin Hydraulique) du Souss-Massa-Drâa |
