Abstract
On the example of the Kursk hydraulic unit of a complex purpose, proposals are given to ensure the accident-free and reliable operation of spillway low-span structures typical for reclamation reservoirs of the agro-industrial complex of Russia. The results of laboratory design of downstream devices at the outlet section of an open three-span spillway are considered. The purpose of the research is to find technical solutions for optimal schemes of the energy damping system that prevent or reduce flow failure due to asymmetrical water discharges during the renovation of the culvert. As a result of the research, a variant of the spreading arrangement was established, which provides a favorable flow spreading at all openings of the spillway spans and safe connection with the downstream without the formation of a flow failure in comparison with the design and existing structural schemes of the culvert section. Behind the spreaders in the zone of maximum pressure deficit, it is recommended to arrange special drainage wells to optimize the parameters of the fastening plates.
