In an interview with the Sputnik Azerbaijan website, the head of the department of geomorphology of the coasts and bottom of the Caspian Sea at the Institute of Geography named after academician H. Aliyev of the Ministry of Science and Education of the Republic of Azerbaijan, Doctor of Geographical Sciences Amir Aliyev, said that the decline in water levels will continue until 2040.
Refuting the arguments of residents of Baku and Sumgait, who link the drying up of the Caspian Sea with the presence of buildings in coastal areas, the scientist noted that the decrease in the level of the Caspian Sea has nothing to do with the buildings built on the coast. According to him, the decrease in water level in the Caspian Sea is the result of a change in the water balance of water. There is less water entering the Caspian Sea than leaving it. If a lot of water comes in, the sea level rises; if a lot evaporates, the level falls.
In recent years, the volume of water from the Volga River, which flows into the Caspian Sea and makes up 85 percent of the water of the Caspian Sea, has decreased to 25-30 percent. Therefore, the decline in sea level is more pronounced.
The level of the Caspian Sea in 1977 was 60-70 cm lower than it is now. Over the past 4,000 years, the level of the Caspian Sea has fallen every 250 years, then risen again. “Currently, the water level in the Caspian Sea is decreasing. “The decline will continue until 2040,” the expert said.
