ИСТИНА

The problem of Caspian Sea level fluctuations and its forecast have always attracted the attention of researchers. This problem worsened in the 20th – early 21st centuries, in connection with an unexpected fall by 3 m (1929-1977), and then with an even more unexpected rise by 2.4 m (1978-1995), and with a new fall by 1,4 m (1996-2018). Of course, such level fluctuations had an impact not only on the coasts, but on the entire infrastructure of the shore. Fall and rise in the level caused a wave of forecasts. They were based on different approaches, but they all have failed. In solving the problem of Caspian Sea level forecasting, the method developed by Doctor of Geological Sciences, prof. G.I. Rychagov – a method of paleogeomorphological analysis based on a detailed study of the small river valleys of the Dagestan and Azerbaijan coasts of the Caspian Sea. This is an example of long-term forecasting, unique for modern geography, which has already been justified twice. This method, based on objective data captured in the landforms and their constituent sediments, is not only as informative as computational methods, but it turns out to be reliable for predicting the level for the near and more distant future. It follows when conducting capital economy on the Caspian shore.
