Abstract: A flood wave propagates from upstream to downstream sections of a river at varying average speeds along the reach. Past research has showed that, for a given reach, the wave speed depends largely on the magnitude of the discharge and as well as the nature of the event. The wave speed is an important parameter in flood forecasting models that use upstream flow measurements as a basis. In this article an approach based on information theory is modified and applied to investigate the dynamics of flood wave propagation and to calculate the wave speed. The approach is tested on reaches of the Dutch part of the Meuse River and the Wye River in the UK. With this approach, it was possible to determine the wave speed corresponding to different discharges.
