Abstract
Study of temporal and spatial variability of maximum water flow is of particular relevance in connection with the increasing incidence of flooding on the territory of theRussian Federation, including on individual rivers of theRepublicofBashkortostan. In this regard, there is an urgent need for a full-scale study flow-forming factors that influence the conditions of formation and variability of maximum water flow. Specified with high reliability allows to perform predictive calculations and to carry out early evaluation of possible scenarios. This will reduce the extent of the negative economic and environmental impacts of water during spring flood. To allow a detailed analysis of the dependence of maximum flow of spring floods from major flow-forming factors within the study area were selected 15 basins of small and medium rivers. It should be noted that the location of meteorological stations to these river basins are not bound. In line with this, we carried out spatial interpolation factors for 14 meteorological stations. With respect to each of the river basins were identified gravitating points, typical indicators, which have been determined by conducting a correlation analysis between the studied factors and maximum water flow by closing sections of the rivers. In the following, relative to the center of the basin progressively defined a weighted average of the basic factors that were used to build regression models describing the dependence of the maximum water flow from them.
