Forecast of the Rainfall Flood Hydrograph on the Far East Rivers

B. I. Gartsman and T. S. Gubareva

A procedure of forecasting the hydrograph of rain-fed rivers four to six days ahead from precipitation data is considered. The forecast procedure is based on basin-indicators. A new element of the procedure is an original model of the flood cycle in a small river basin used as a first element of the entire rainfall–runoff transformation scheme. Application is discussed of the complete prediction algorithm, given the necessary number of basin-indicators, and the incomplete algorithm that is adapted to a real state of the observation network in different ways.
