Abstract

Tidal marsh-watercourses form a significant link between marine and fluvial environment. As consequence bi-directional forces due to asymmetric tides and inland runoff deform morphodynamic processes with presence of cohesive and organic sediment. In combination with the high inter-tidal area proportion and additional anthropogenic deformations special requirements for the long-term approach restrict existing methods. This paper exposes significant processes in tidal marsh-watercourses based on a research study. The identified processes were integrated into a specified long-term approach taking these special requirements into account. By using a numerical model the range of uncertainty for different impacts were considered and results in a long-term riverbed evolution.
