Application of the Racine Gumbel and CUSUM Laws in Water Resource Management: Case of the Tit Zil Spring (Guigou Plain - Morocco)

This study aims to provide a spatial diagnosis of the state of water resources in the Guigou plain, by monitoring the quantitative evolution of precipitation since the 1970s. This study is based on two key indicators to determine the evolution of the flow of Tit Zil source, as well as the flow of the Guigou River at the Ait Khabbash hydrological station, located approximately 11km from Tit Zil source. The results are obtainted trough Field works which manifest a great fall back of water ressources. This fall back is due to many factors, natural factors legislated on drought mankind over exploitation since in the 80th. As well as, the changing mode of exploitation leads to emergence of conflicts between tribes.
