An approach that combines runoff model & stochastic weather generator in order to get the coordinates of yearly, monthly, daily, maximal & minimal runoff frequency curves is considered. The distributed hydrological model “Hydrograph” and stochastic weather generator were applied to the catchment of the Pasha River (5710 km2) located in the Northwest Russia. The frequency curves are compared with analogous ones that have been built on the basis of the long-term runoff observations.
