The existing theory for shore-transverse rhythmic sand bars relies on morphodynamic instabilities involving the wave-driven longshore current and rip currents. Intriguingly, transverse finger are common coasts with sediment excess, something not related to those Here we show that, if actual beach profile is above equilibrium profile, cross-shore transport can induce an instability triggered by ...

The macrotidally influenced harbor of Dagebüll on the North Sea coast Germany features a piled south jetty, for which provided constructive designs are investigated regarding their potential hydro-morphological impacts area and adjacent navigational channel. experiences steady accumulation sediment. This results in reduction depth necessitates regular maintenance dredging constituting cost aspe...

The formation and development of tidal channels salt marshes are controlled by complex interactions between hydrodynamics, sediment transport, vegetation dynamics. Tidal affect and, at the same time, affected growth fringing them. coupled evolution these morphological units, mediated growth, is thus a key ingredient for simulating behavior environments. Considering two factors, we developed mat...
