Simulation of Flow in Rivers and Tidal Channels with an Implicit Finite Difference Method of the ADI-Type

摘要

In order to make predictions for the morphology of an alluvial bottom a thorough knowledge of the flow pattern is needed. In tidal channels, without a net discharge over the tidal period, the main flow effects on the morphology will, on an average, remain relatively small because of the tidal variation. Therefore second order flow phenomena become important. This research, which is financially supported by the directorate of the Deltadienst of Rijkswaterstaat, concerns the determination of the secondary flow in tidal channels like estuaries as the Eastern Scheldt based on a known depth averaged velocity field.
