Field studies of riverbed and wind flows characteristics in the southern part of the Gorky reservoir
The paper presents the results of a study of currents in the southern part of the Gorky reservoir using the Acoustic Doppler Current Profiler (ADCP). Similar work was systematically carried out in the water area of the reservoir in the 60-80s of the twentieth century and the previously obtained data are still used to solve a number of practical problems. The lack of fresh data on the currents served as the motivation for this work. Study of the flow structure has been carried out. An analysis of the data showed that the structure of the flows is characterized by significant heterogeneity. Features of the flow structure have been identified at the weak south wind conditions and the low water flow through the Nizhny Novgorod hydroelectric station. The formation of the whirlpool observed in the upper layer of the reservoir was shown. Probably the possible features of the flow structure are determined by bathymetry in the floodplain of the reservoir with the relatively large water flow through the hydroelectric station and the north wind conditions.
