Abstract
Objective: To substantiate the feasibility of construction and reconstruction of fishspawning channels on the cascade of low-pressure Lower-Don hydroelectric power plants.
Materials and methods. The factual basis of the study was the materials of surveys and studies of existing fish-spawning channels at the Nikolaevsky and Konstantinovsky hydroelectric power plants and their design solutions at the Bagaevsky and Kochetovsky hydroelectric power plants.
Results. The description of the advantages and disadvantages of near-hydro-node fish-spawning channels, the conditions of their functioning, their purpose and layout and design features is given. The general information about the conditions of natural reproduction of passing and semi-passing fish on the Lower Don is given, and the justification of the possibility and expediency of using near-nodal fish-spawning channels for their improvement is given. The general characteristics of existing and projected structures are given. Proposals have been formulated for the reconstruction of the channels at the Nikolayev and Konstantinovsky and for improving their design solutions at the Bagaevsky and Kochetovsky waterworks.
Conclusions. 1. A proposal has been made for the construction and reconstruction of Bagaevsky, Kochetovsky, Konstantinovsky and Nikolaevsky fish-spawning channels. 2. The requirements for the layout and design solutions of hydro-nodal fish-spawning channels arranged as part of river low-pressure waterworks are determined.
