The Hungarian Hydrological Forecasting Service has a long history in model based hydrological forecasting on the Danube catchment. An extensive set of semi-distributed rainfall-runoff models with advanced snow calculation serve as a basis for the operational daily forecasting completed with discrete linear cascade models of non-integer and integer cascade numbers solved based on the state-space approach for accurate flow routing. In this paper we present an additional module of the forecasting system, a tailor-made one dimensional hydrodynamic model. The model is developed for fast and robust simulation with assimilation observed data to provide support for flood management decisions and more accurate operative water level prediction. The model is based on the Verwey variant of the Preissmann scheme solved by the double sweep algorithm. It handles complex river networks with dry beds. The data assimilation algorithm provides a longitudinally valid update of the simulated water levels resulting in a continuous water surface.
