Real-time updating procedures considerably improve the performance of rainfall-runoff models for short-term forecasting. Updating procedures such as error prediction or state variable based on Kalman filters are the most typical methods used in the literature. The aim of this project is to develop a rainfall-runoff forecasting model with updating procedure. The studied basin, the Brue catchment, is located on the SW England and has 135 km2. It is modelled with the IHACRES model as well as with RS MINERVE to compare the influence of the updating procedures on different hydrological models.
