Abstract

For the first time, the relationship between the surge and intrusion mechanisms and the temporal variability of vertical water stratification during the penetration of brackish water from the Vistula lagoon into the channel of the Downstream Pregolya branch, on the one hand, and hydrometeorological conditions, on the other hand, was analyzed. The range of brackish water penetration into the channel of the Downstream Pregolya branch was evaluated using the Keulegan method. The data of hydrological measurements for the period September 10, 2019–March 27, 2020 and the features of the channel geomorphology were used to assess the possibility of brackish water penetration up the channel of the Downstream Pregolya branch to the bifurcation point of the Pregolya River with subsequent flow into the Deyma branch.
