   Speaking on the sidelines of the Third Conference on Rapid Sea Level Change?a Caspian Perspective, May 2-9 in Rasht, Nader Narimanzadeh added that Caspian Sea undergoes more changes compared to other seas and oceans in terms of water level, hydrologic and hydrochemical characteristics.
   He noted the sea level has risen between 14 and 20 centimeters annually over the past 20 years, while similar changes in other seas and oceans would take a minimum 100 years.
   Narimanzadeh said Caspian Sea is a natural laboratory for scientists, noting that presently three projects on rapid changes of sea water levels, particularly in the Caspian sea, are being conducted by the Netherlands’ Delft University of Technology and UK’s Bronlen University and Germany’s Meteorological Institute (MIHU)--and with the financial support of United Nations Education, Scientific and Cultural Organization (UNESCO).
   Based on research conducted by Professor K. Arpe from Germany’s MIHU, Caspian sea level would increase by another two meters by 2075, he recalled, citing global warming, rise in precipitation level and increase in rivers’ inflow, particularly through Volga River, within the next 70 years as prominent factors behind the surge.
   Commenting on the satiation of Gilan coastlines in case of further increase in sea level, Narimanzadeh said, “Everything will depend on the slope of coastal areas--the less steep the land, the heavier the damage.“
   Stretched over an area of 371,000 square kilometers, Caspian Sea contains about 78,000 cubic kilometers of water.
