Abstract
Coastal zone management needs the prediction of the changes in shoreline and coastal profiles, where the fluctuation of sea water level plays an essential role. Climate change and human activities have accelerated the fluctuation/falling of water levels in lakes and enclosed water basins. Using satellite images and cross-shore beach profiles at twelve monitoring stations along the southern coasts of the Caspian Sea, the effect of the rapid fall of water level on the nearshore morphology is studied in this research. Radiometric and atmospheric corrections are made on satellite images, and the NDWI index is used to increase the accuracy of the shoreline extraction. Comparing the accuracy of different methods, it is concluded that the Hands (1984) formula relatively better predicts the shoreline advancement rate due to lowering water level.
