Unveiling shoreline dynamics and remarkable accretion rates in Lake Eğirdir (Turkey) using DSAS. The implications of climate change on lakes
Lakes and their shorelines are important ecosystem areas with the diversity of living species they host. In addition, lakes are an almost indispensable resource for humans as a source of fresh water. Global climate change causes changes in lake surface conditions such as ice cover, surface temperature, evaporation, and water level. To understand the vulnerability of lakes to global climate change, researchers study the temporal rates of change that occur on lake shorelines. Shoreline monitoring contributes to important steps such as lake shoreline management, shoreline change, erosion monitoring, flood forecasting, and water resource assessment. Therefore, in this study, Landsat ETM+ multi-temporal images of the east part of Isparta Eğirdir Lake were obtained and the change in the shoreline over a 10-year period (2013-2022) was examined using the DSAS (Digital Shoreline Analysis System) tool. As a result of the study, very high levels of accretion were observed in the entire 82 km area examined in Eğirdir Lake. The highest EPR (53.79 m/year) in transect ID 149 and the highest LRR (60.87 m/year) in transect ID 26 were observed. These values are well above the +2m/year EPR (End Point Rate) and LRR (Linear Regression Rate) values, which means very high accretion.
