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
