【 摘 要 】

The time of the concentration of the basin is a more important parameter for forecasting the response of a river basin to a given amount of precipitation, and therefore it is important in the development of hydrological models. The values of the concentration time are determined based on the empirical equations of different authors. The paper presents various empirical methods used on a hydrologically non - isolated basin. On the basis of the calculated values of the time concentration of the basin, hydrographs of large waters of the centennial return period were determined. In this way, estimates of uncertainty in determining the peak flow and volume of the hydrograms of the outflow from the basin due to the budget of the river basin concentration were estimated.
