Full-scale study of the river level regime of the Volga River in the lower reaches of the Nizhny Novgorod HPP

Abstract

In the summer of 2021, full-scale studies of the river level regime were carried out on the Volga River section in the lower reaches of the Nizhny Novgorod hydroelectric power station. For this purpose, six temporary water measuring posts were equipped throughout the site, according to which water levels were measured during daylight hours. According to the results of the study, the main characteristics of the release wave formed during the daily regulation of the runoff at the Nizhny Novgorod hydroelectric power station were obtained, including the wave amplitude, periods of rise and fall of the water level in various sections of the site, changes in the slope of the water surface during the day. Based on the data obtained, conclusions are drawn about the possibility of their application in the dispatching regulation of fleet movement at the site and the implementation of design and scientific work
