Seasonal monitoring of the surface water in chott merouane by remote sensing

Abstract

Surface water in watersheds is an essential element in the study and development of their roles in any hydrological system. However, rapid and accurate surface extraction is a major challenge because of the spatial diversity of the objects on the earth surface. Remote sensing through its spatial, temporal and synoptic capabilities becomes a very powerful tool in this type of problem. The results of our study show that watershed of salt lake or (chott) merouane cover 130,6014km² in january 2022 and it goes down in august to 19.5618km² during the summer due to the effect of high temperature and thus an increase in evaporation and it goes high in december 2022 to 116.6084km² Surface water of chott merouane do not dry completely due to the continuous drainage from canal oued righ , this canal contributes to supllying the chott with water maintaining a certain water level
