The influence of hydrographic factors on the size of rainfall floods on the rivers of the Belarus
The article describes the results of the analysis of influence of hydrographic factors on formation of rainfall floods on the rivers of the Belarus for the period of instrumental observations. The regional mathematical models are constructed. If the supervision on the rivers is absence, the received models allow to define the maximal charges of water of rainfall floods of 5% probability with sufficient accuracy for practical calculations. Rates of transition from 5 % probability to other probability are received.
