Abstract
The article regards the movement of the negative and positive release waves from the reservoir on the Oredezh River. There was a model of unsteady water motion used for calculation the spread of the release wave. The release was conducted on 06/19/2017 and consisted of three phases. In the first phase, the gate was closed and the water discharge fell from 3.6 to 2.5 m3/s. An hour later the gate was raised and during a half an hour water was released with an average flow rate of 4.2 m3/s. There were 7 points organized to monitor the dynamics of water levels in the river. They were located at a distance of 91.5 to 2443 m from the dam. The observation interval was 1 minute on most targets. There is advisable to use a one-dimensional model of unsteady water motion (Saint-Venant equation) for calculating small release waves of slowly changing unsteady water motion in cases where topographic materials are available. This allows to determine...
