Abstract
Purpose. The subject of research is maximum runoff of spring flood in Severski Donets river basin. The task intention consist in substantiation normative-calculation base and on its ground to accomplish a spatial generalization of data of maximum runoff of rivers in Severski Donets river basin. Methodology. For calculation of characteristics of maximum runoff of spring flood have suggested a great deal of calculation schemas and formulas. At present-day stage it classify for two group. First group it is empirical and semiempirical methods. Second group is methods that base on theory of channel isochronal. At present day we used regulations on calculation of characteristics of maximum runoff of spring flood on territory Ukraine in particular SNiP 2.01.14-83, refer to first group. The main disadvantage of regulations is neglect of major factor forming flood s that have been limited to use in different physiographic conditions. On the other hand, methods lean on theory of channel isochronal do not have necessary of quantity of starting material of hydrological regimen of river and temporary watercourse. The authors have proposed the computational scheme, it which is based on the geometrical model of reduction hydrograph. The basic data are maximum modulus and two transformation functions – channel and channel-inundable regulation. Finding. The methods have been realize as exemplified in supervisions over maximum runoff of spring flood in Severski Donets river basin. Propose structure design formulas have been distinguish from that she is universal from the point of view of dimension columbine and genetic type of floods and freshet. Results. The m ethods have been lead to the level of direct practical use instead of obsolete regulations SNiP 2.01.14-83.
