- This paper deals with adaptive flow forecasting from discharge observations, with catchment rainfall as an additional input component. The precipitation input is pre-processed by approximate expressions of excess rainfall and routed by a linear cascade model. The basic equations of the algorithm and the general pattern of the computer program are presented. Examples are given for a case study area (Västerdalälven River in Sweden) where rainfall input in addition to the flow observations was used to improve the forecast accuracy. The results are discussed.
