Abstract

The paper begins with discussion of trends, observed throughout the world, towards reconstruction and modernization of small water power plants. The ecological importance of these objects is emphasized. Attention is brought to the fact that ecological considerations become more and more appreciated in the majority of European countries and that the number of countries where small water power plants are built is rising. An opinion is expressed that in this country the main effort should be made towards restitution and modernization of existing water power plants making possible their fully automatic operation.
