The Dam Sidi Chahed is located downstream of the Mikkes and Lmaleh rivers. It's located about 30 km at the NE of Meknes city and about 30 km at the NW of Fez city on the main road between Fez and Sidi Kacem. It was commissioned in 1997 and has a capacity of 170 million m3. It crosses three different structural units with the Middle Atlas to the south, the basin know the center and south-north Rif wrinkles. The use of ArcGIS and Global Mapper has been used to characterize the edge of the dam and its retention Sidi Chahed from ASTER images making several thematic maps which are: the map contours, the DTM, the map slopes and their exposure, thematic map of sub-basins, the thematic map of the river system and its classification, the superposition of the structural and drainage networks, thematic map of rainfall and late distribution maps of physico-chemical parameters. From thematic maps produced for the watershed studied, several geometric calculations were performed to characterize the watersheds under long view, width, equivalent rectangle, area, perimeter and compactness index. These parameters indicate that sub tanks are elongated favoring low flow rates, a greater flow of water and a total amount of time of considerable precipitation harvested. Rainfall results, which were obtained from the isohyets maps are divided into 7 classes with lower values since the Middle Atlas at the south (850 mm) to the Sidi Chahed dam at the north (450 mm).

Abstract
The Dam Sidi Chahed is located downstream of the Mikkes and Lmaleh rivers. It's located about 30 km at the NE of Meknes city and about 30 km at the NW of Fez city on the main road between Fez and Sidi Kacem. It was commissioned in 1997 and has a capacity of 170 million m3. It crosses three different structural units with the Middle Atlas to the south, the basin know the center and south-north Rif wrinkles. The use of ArcGIS and Global Mapper has been used to characterize the edge of the dam and its retention Sidi Chahed from ASTER images making several thematic maps which are: the map contours, the DTM, the map slopes and their exposure, thematic map of sub-basins, the thematic map of the river system and its classification, the superposition of the structural and drainage networks, thematic map of rainfall and late distribution maps of physico-chemical parameters.

Abstract: (french)
Le barrage de Sidi Chahed est situé en aval des oueds Mikkès et Lmaleh. Il est situé à 32 km au NE de Meknès et à 32 km au NW de Fès sur la route principale reliant Fès et Sidi Kacem. Il a été mis en service en 1997 et doté d'une capacité de 170 Mm3. Il traverse trois ensembles structuraux différents : le Moyen Atlas au Sud, le bassin de Saîs au centre et les rides sud-rifaines au Nord. L'utilisation des logiciels SIG a permis de caractériser la zone du barrage Sidi Chahed et sa retenue à partir des images ASTER en réalisant plusieurs cartes thématiques dont on peut citer : la carte hypsométrique, la carte des pentes et de leurs exposition, la carte des sous-bassins versant, la carte thématique du réseau hydrographique et sa classification, la superposition des réseaux hydrographique et structural, la carte géologique et en fin la carte thématique de la pluviométrie. A partir des cartes thématiques réalisées pour le bassin versant étudié, plusieurs calculs géométriques ont été effectués pour caractériser les sous bassins versant de point de vue longueur, largeur, rectangle équivalent, surface, périmètre et indice de compacité. Ces paramètres indiquent des sous bassins de forme allongée favorisant les faibles débits, un temps d'acheminement des eaux plus important et une quantité totale récoltée de précipitations considérable. Les résultats pluviométriques mettent en évidence des isohyètes reparties suivant 7 classes avec diminution des valeurs depuis le Moyen Atlas au Sud (850 mm) jusqu'au barrage Sidi Chahed au Nord (450 mm).
