Abstract
Given the vastness of the environment, modern methods for its monitoring its behavior and changes are of great importance. The Neka power plant uses the Caspian Sea to cool its machines, and then the return water is discharged directly from the power plant into the sea. So far, no precise, economical method has been provided for detecting thermal pollution in marine resources in the previous studies. Therefore, this paper proposes a method for detection of thermal pollution through remote sensing and satellite imagery. Landsat 8 can calculate the water temperature with the OLI and TIRS sensors. In this study, the water temperature around the Neka power plant was calculated at the eastern channel (the water inlet channel from the sea to the power plant) and the western channel (the water outlet channel from the power plant to the sea) in two different images using the separate window algorithm in MATLAB. The results indicated an increase in the temperature in the western channel. For the western channel, the mean and highest temperatures on May 26, 2015, were 292.7 K and 294.3 K and were 300.5 K and 303.4 K on April 10, 2016. Based on the results, this can have environmental impacts due to water thermal pollution.
