Distinct patterns of interactions between vegetation and river morphology

Distinct patterns of interactions between vegetation and river morphology

Modelling vegetation and morphodynamics is often one-way traffic that either takes into account the effect of vegetation on morphodynamics or vice versa. The few models that do incorporate an interaction have until now represented vegetation as cylinders causing hydraulic resistance that do not change over time. We coupled a morphodynamic model...

Bifurcation dynamics and avulsion duration in meandering rivers by one-dimensional and three-dimensional models

At river bifurcations, water and sediment are divided over two branches. The dynamics of the bifurcation determine the long-term evolution (centuries) of the downstream branches, potentially leading to avulsion, but the dynamics are poorly understood. The long-term evolution can only be studied by one-dimensional models because of computational...
