Abstract

The Coleman et al. (2005) time-lag approach for prediction of bed form dimensions in rivers was originally developed for steady discharge. In this study, the time-lag approach was adapted for application under discharge waves. The application on a discharge wave in a flume experiment shows that including the time-lag approach, enhances the amount of hysteresis between discharge and roughness and may improve the prediction of peak water levels in an operational water level prediction model.
