The Problems of Increasing the Efficiency of Operation of the Right Channel of the Akhuryan River

Year: 2024

Type: article

Abstract: A distinctive feature of mountain rivers are significant riverbed slopes, alluvial channels, sometimes composed of boulders and rock fragments, steep banks and the presence of rapids and rapids. In such conditions, it is sometimes impossible to build ladder fish passages, the average slope of which is very often less than the slope of the riverbed. Meanwhile, these rivers are currently the most attractive for the construction of small hydroelectric power plants of the derivational type. Studies of more than 120 designs of existing fish channels at the water intakes of small mountain rivers in different countries show that the design solutions and geometric dimensions of their execution, as a rule, do not ensure the free migration of fish upstream.
