The goal of this study was to check the climatological, hydrological, hydrogeological, topographical, and also vegetation cover situation of the wetland by using the google earth engine cloud system and calculation of current and future hydrological water balance of the wetland. For this purpose, data from TRMM, MODIS, Terra, LANDSAT, GRACE, and ALOS satellites were used. The results showed that GEE has a lot of potential and application for preparing time series and monitoring areas where little information is available about its past situation. According to the rainfall of ۱.۱۳۳۳ mm۳, surface runoff of ۱۲.۲۰ mm۳, and evapotranspiration of ۱۳.۸۷۵ mm۳ in the wetland area, the water balance of the wetland is -۰.۴۵۲ mm۳. This amount indicates the volume of water that the wetland has based on climatic and hydrological relations. This amount will be equal to ۱.۴ mm۳ in ۲۰۴۰, which shows that the wetland condition will improve in the future.
