Kiriyak S. Zoning plain territory of Ukraine for the duration of the inflow of water from the slopes to the stream network.

The оbject - maximum flow of the spring flood of the rivers plain territory of Ukraine; the aim -rationale of scientific and methodological basis for distinguishing between the flat territory of Ukraine on the characteristics of the estimated duration of the slope flow spring tide; methods - statistical analysis, joint factor analysis, the spatial generalization of the design characteristics of the maximum runoff; the results - he rationale and implementation methodology zoning plain territory of Ukraine for the duration of water flow from the slopes of a channel network; the novelty a map of the maximum runoff of spring flood layers 1% probability of exceeding, are calculated and summed across the coefficients of the slopes of transformation, the values of the duration of water flow from the slopes of a channel network of rivers, as well as factors time irregularity in stream flow during the spring flood, proposed a schematic map of zoning plain territory of Ukraine for the landscape and hydrological characteristics, to refine the calculation formula SNIP 2.01.14-83;the introduction degree - is planned to introduction; the branch of using -- in water management and planning organizations in the calculation of the maximum runoff of rivers.
