This article shows the results of hydrological studies on the river Don around water-intake facilities in Rostov-on-Don. The factors of wind-surge influencing ecstatic increases in the water level of the receiving basin are presented. The uneven seasonal and long-term flow river regime leading to intensive channel deformations was evaluated. A low water discharge, causing an active rift deformation within the saddle was of a high river-forming significance for the natural water flow due to a high amount of water irrespective of the yearly water content. However, the river reformation occurred mostly during a high water discharge (flooding): the floodplain was subdivided into separate arrays of channels and creeks constituting several branches within the floodplain. These deformations facilitated the formation of the easily washed floodplain alluvium. These deformations occurred mainly during years with the abundant rainfall. For a relatively short period of time (the flood period) the most significant river bed deformation occurred during the natural flow. Hydrographs were drafted according to the results of the studies on the water-level regime.
