Typology of the physic-chemical quality of the waters of the dam Sidi Chahed-Morocco [Typologie de la qualité physico-chimique de l'eau du barrage Sidi Chahed-Maroc]

In morocco,countries with semi-arid climate,the increasing requirements out of water for the irrigation,the production of electricity and the drinking water supply,required the construction of a great number of dams. this infrastructure must enable him to provide for its needs and to carry out a better management of its surface water resources. the basin saïs is located between the part of the average low executory atlas and the point located in the prérif one and the plain of gharb. the dam sidi chahed,fact part of the catchment area of sebou,the setting in water of the stopping was carried out in 1998; the vocation of water of the stopping is primarily the drinking water and the irrigation. this study related to the physicochemical quality of water of the stopping and its emissary. to complete our work,we carried out,a monthly follow-up,are spread out december 2012 at november 2013. the analyses related to 15 chemical physico parameters,these results showed that the quality of water of the stopping and those of its emissary has a very significant mineralization,and corroborated those obtained by the application of the analysis in components principales (acp) by thus confirming a saisonnality of the physicochemical parameters between the studied stations.
