Regulation in the Volga river, 1934 compared to 1999
Year:
2007
Author:
Philippe Rekacewicz, UNEP/GRID-Arendal
Description:
The construction of a large number of dams and industrial facilities on the rivers feeding the Caspian has caused a significant change in the quantity of water inflow. The creation of a succession of large reservoirs, especially on the lower and middle Volga, has led to significant losses in flow rate due to additional evaporation from the surface of the water.
