HYDROLOGICAL SERIES OF SMALL RIVERS IN THE SLAVSK DISTRICT OF THE KALININGRAD REGION

The article presents the results of hydrological calculations for small watercourses located in the Slavsk district of the Kaliningrad region. This territory is of considerable interest, as it contains the largest array of polder lands in the region. At certain periods, systematic observations of the hydrological characteristics of some water bodies were carried out on the studied territory: Zlaya river - Krasnoznamenskoye village, Osa river - Priozerye village, Nemoninka river - Timiryazevo village; currently there is only one hydrological post. In this work, taking into account the requirements of regulatory documents, the choice of analogous rivers is justified: for Zlaya river - Instruch river, for Osa and Nemoninka rivers - Zlaya River. According to the data of hydrological observations and the restored values, theoretical probability curves of average annual discharge of the studied rivers are constructed and the values of average annual discharge of various probability are determined. The data obtained can be used in the performance of engineering surveys, the development of measures aimed at the sustainable functioning of water management systems, the determination of ecological runoff.
