Introduction. In today’s climate change and observed changes in the water regime of rivers, including the spring flood runoff. An important role in the formation of runoff during spring flood play of factors an underlying surface and climate in basin of the Southern Bug.
Purpose. The aim is analyze hydrometeorological conditions of formation of spring flood in basin of the Southern Bug and research of trends to modern climate changes and their impact on the characteristics of maximum flow spring flood of the rivers on study area.
Methods. The paper used the methods of theoretical analysis, geographic aggregation, statistical processing of time series of hydrometeorological observations.
Results. Established that long-term course of hydrometeorological factors and characteristics of the runoff spring flood points to cyclical fluctuations in their expressed decreasing trend (except temperature) over the past decade.
Conclusion. Trends of time course of hidrometeorological factors and characteristics of spring flood in river basin of the Southern Bug should be refined with further accumulation of observational data in today’s climate change and water regime.
In the article considers the scientific and methodological approaches to the improvement of parameters formulas of maximum runoff of rain and floods of spring floods.
To regulation design characteristics of the maximum spring flood runoff in the basin of the Southern Buh River was used structure, which is based on isochronous channel theory.
It is substantiated the method of calculation and the spatial generalization of the mean multi-ancient layer of flow and maximal modules of spring flood on the lowland rivers of Ukraine.
The settlement meanings of the characteristics of slope inflow are received during a spring high water on the rivers of a Podolsk height. The estimation of influence of the local factors on of slope inflow and generalization of this parameter on territory is executed.
The scientific – methodical recommendations concerning spatial generalization of the characteristics of spring flood runoff on an example of the rivers of a Podolsk height are given.
