Shahid Abbaspour Dam area is the largest part of Karun Bozorg which had been exposed to floods twice in 2019. Given the strategic importance of the basin and recent floods, the present study uses Landsat 7, Landsat 8, Google Earth Engine and NDWI algorithms at low cost and low time to isolate the water phenomenon from other phenomena for review purposes. The changes in the area of ​​water areas in this basin have been addressed in the last 20 years. In these studies, the area of ​​all water areas in this catchment area has been calculated and based on it, the changes in the area of ​​water areas resulting from the floods of recent years; It is really efficient to be obtained for managing of water resources, crisis management and to achieve sustainable development of the region. The results of this research show that in the mentioned basin, the highest volume of water was in 2019 and the reservoirs and dams were filled with water, so that with a time difference of one month, 25 square kilometers have been added to the volume of their water. According to this information, the risk of flooding covers residential and agricultural areas, and the lack of serious supervision and attention to this issue can cause irreparable damage in the near future.
