 The study simulated sea water level, SWL, using total inflow from feeder rivers and precipitation and evaporation over the Caspian Sea, determined potential vulnerable areas of the sea over the past 80 years by comparing minimum and maximum annual water body maps, and used linear regression between SWL rise and covered potential vulnerable area, CVA, to determine desiccated areas in different regions of the Caspian Sea due to changes in precipitation, evaporation and total inflow. The results showed that 25,000km2 of the sea is potentially vulnerable to SWL fluctuations in terms of desiccation, with 70% of this vulnerable area located in Kazakhstan. Potential vulnerable area per kilometer coastline was found to be 6km2 in Kazakhstan, for kilometers 2 in Russia and whole of Caspian Sea, 1.5km2 in Iran, 1km2 in Azerbaijan and 0.5km2 in Turkmenistan. The study also indicated that SWL in the Caspian Sea is sensitive to evaporation and that a 37.5mm decrease in mean annual net precipitation would lead to a 1875km2 decrease in the sea area, while a 1km3 decrease in mean annual inflow would lead to a 1400km2 decrease in the sea area. The developed framework can be used to assess future changes in SWL and sea area due to anthropogenic activities and climate change.
