Abstract
The problem of the harmful effects of seasonal flood waters in the Volyn river basins is of high current importance, since the Pripet and Zahidny Bug rivers are transboundary, and frequent floods are a problem not only for Ukraine, but also for neighboring states. By the nature of the flow distribution, the region’s rivers are of the Eastern European type characterized by a high spring flood, a summer watershed that is intermittently interrupted by showers, and increased autumn flow. Climate change leads to some redistribution of intra-annual runoff, where the spring flood becomes less distinct (stretched in time), with no peak maximum flows. Torrential rainfall in the summer contributes to short-term increase in the level of surface water in the rivers of the region. As a result of harmful effects of spring floods and flash floods and their stretch over time, of significant areas of land in the region are flooded which amounts to about 8,000 hectares located mainly in the northern districts (Ratne, Kovel, Lyubeshiv, Kamin-Kashirskyi). This problem is most acutely manifested in the territory of the Lyubeshiv and Pripet exploitation districts: the largest area of flooded land is located in the Tsyr, Bykhiv, Korostyn drainage systems (2350–1200 ha), as well as in the Samariv and Zabolottia territorial communities (1200–1030 ha). Observed at the reclamation systems in Volyn are water overflows through the dams which have subsided over time and require capital repairs rather than constant maintenance, as the overflows lead to flooding or inundation of populated areas. A set of economic measures is held annually in the Volyn region to reduce the harmful effects of floods waters.
