The areas of flooding and the intensity of the process are constantly changing. In
recent years, the largest areas of flooding have been recorded in the southern regions
such as Kherson, Mykolayiv, Odessa, where the process develops not only within the
floodplains, above-floodplain terraces and the bottoms of large beams, but also on
watersheds that are characterized by very poor natural drainage. In general, for the
southern regions of the territory of Ukraine, the process of flooding, first of all, is
connected with the technogenic conditions for the formation of the position of
groundwater levels [3].
A rise in the average annual level of groundwater over a long period of time is
observed at an average rate of 0,1-0,3 metres per year.
