Abstract :

So far, many studies have been conducted to identify and detect land cover changes and land use changes. Optimizing land cover monitoring is an inevitable necessity in natural resource management. Given the evidence and effects of climate change in the region and the declining and increasing trend of some coverages and land uses can be effective in prioritizing conservation and zoning strategies. Factors such as land resources, environment, population, economy and society must be taken into account for sustainable development. Any type of development, regardless of quantity or quality, has specific environmental effects (1). Over time, dam construction has made some changes in the land cover - use of dams, in this study we aim to detect these changes. Therefore, for detecting cover changes - upstream and downstream of the Khordad 15 Khordad Dam during the period 201–990 1990, first visualize the changes using Googel Earth, then use Landsat 5 (1990 image) before. Dam Construction and Landsat 8 (Picture 2019) After dam construction and flooding using ENVI software, visual and automated changes detection are performed and the results of automatic image changes and classification in two classes Modified and unchanged Accuracy was 86.38% and was unchanged and modified by classification into three classes ( Decreased) reached 85.51% accuracy.Key words: Sustainable development,RemoteSensing,Dams,Change Detection,Classification.
