RS-Based Assessment: Spatial-Temporal Changes in Water Basins of Tar and Havir Lakes

In recent studies several factors such as landslides, volcanoes, glaciers, tectonic and karst forms flooded pulleys resulting of karsts development cause the formation lakes in mountainous areas. The mountain Iran, including Tar Havir lakes, are mainly formed by landslides. this research investigation water basins changes for (Tar Hoyer lakes) remote sensing method period from 2013 to 2022 have been done. It has tried select appropriate Landsat 8 satellite images terms cloud cover image quality time when full water. training testing data were selected with same distribution whole make classifications more accurate. After estimate kappa coefficient overall accuracy all kind supervised unsupervised methods, results obtained two classification methods maximum likelihood support vector machine linear kernel conclusion was that better distinguish land areas it is best classifying located amount had increased 2017but 2018, area ​​both decreased significantly, 2019, largest observed calculated. 2020, there no big change ​​the 2020 2022, decreasing.
