Time series analysis of the Caspian Sea shoreline in response to sea level fluctuation using remotely sensed data

The Caspian Sea (CS), biggest inland water worldwide has experienced around 3 m oscillation in sea level during the 20th century. These rapid fluctuations have had a great impact on coastal habitat this sea. Therefore, study is aimed to investigate long-term changes of western part shoreline and Anzali lagoon their dynamic responses fluctuation using time series analysis remotely sensed data over 40-years. To end, area perimeter Lagoon were extracted from Landsat satellite imagery (1975 till 2016) by an automatic procedure including combination Tasseled-Cap texture filter methods. Afterwards, erosion/accretion rates evaluated Net Shoreline Movement (NSM) End Point Rate (EPR) techniques. Finally, CS, through multiple altimetry relationship between relative CS studied. Results positions period (1975–2016) indicate that whole subjected accretion erosion 20.37 -19.22 (m/year) respectively. There balance EPR all transects periods 1975 2016. This shows when happens region, will be happened another behavior symmetrical. When decreased, values showed accretion/seaward vice versa. So, movement strong nonlinear response with coefficient determination −0.66. Also results show 0.78 for fluctuation. greatest lowest its 2003 1985, respectively, which are matched high low stands Level.
