Nowadays, increasing population and, consequently, increasing water requirements is a serious threat to water resources. Due to the scarcity of water resources, issues related to the quality of water resources are of great importance. Due to the fact that surface water is more polluted than groundwater, one of the most important issues related to the operation and environment of dam reservoirs, which are considered as artificial lakes, is to check the water quality of dam reservoirs. In this study, using remote sensing techniques and using Sentinel-2 satellite images, the trend of spatial distribution changes of two parameters of turbidity and nitrogen was investigated. The results showed that rainfall (investigated events) caused changes in the amount of turbidity and nitrogen in the water of the Sepidrud Dam reservoir.
