摘要：

Aguelmam Sidi Ali Lake is an endorheic depression located in the volcano-karst environment of the Moroccan Middle Atlas. this permanent depression of about 44m depth is mostly fed by karst springs and meteoric runoff waters. The regular observations from the lake's banks has found that a very sensitive withdrawal of their level of submersion during the dry years. The purpose of this project is to present the spatiotemporal changes model of Aguelmam Sidi Ali Lake during the period 1985-2015 through the application of the Modified Normalized Difference Water Index (MNDWI) and Water Ratio Index (WRI) using the Landsat 5-TM and 8-OLI images. The Overall Accuracy and Kappa Coefficient were calculated to assess the accuracy of the results. The results indicate an intense decreasing trend in the Lake in the dry period 1985-2007. During the wet period 2007-2015, the results show a progressive increasing trend of the level of reference covering about one third of its surface.
