Present spatial changes of time and duration of spring flooding in the Prypiat River catchment (Ukrainian part)

Abstract

The research of changes of the maximum river runoff under the  influence of climate change is one of the  most urgent tasks of Ukrainian hydrologists. In this regard, spatial change research of the time and duration of spring flooding in the  present climate conditions in the  Ukrainian part of the Prypiat River catchment has been done. The dates of the spring flood beginning and end, the dates of maximum water discharges and the  spring flood duration in the rivers of the Ukrainian part of the Prypiat River catchment have been analysed. Changes of the above-mentioned characteristics have been detected after 1989 in the  researched catchment territory. The  maps of changes of the dates of maximum spring water discharges, dates of the beginning and end of the spring flood and its duration in the Prypiat River catchment (Ukrainian part) compared to the first rated period (up to 1989) have been constructed.
