Morphodynamic regime and long‐term evolution of meandering rivers

Procedural generation of meandering rivers inspired by erosion

This paper describes a method of procedural generation of meandering rivers inspired by erosion, which can enhance visual realism of virtual terrains. Terrain is represented using an adaptively subdivided triangle mesh with additional information (e.g. amount of soft deposit) stored in vertices. Water is simulated using Smoothed Particle Hydrodynamics (SPH), modified in order to model erosion o...

Reverse Meanders, Pseudo Point Bars, and the Enigma of Meandering in Braided Rivers

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

[1] 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 costs. For such models, a relation describing ...

Evolution of Marine Morphodynamic Modelling: Time for 3-D?

The question whether it is time for marine morphodynamic models to take into account the 3-D nature of water and sediment motion is discussed starting from practical demand and the state-of-the-art in basic knowledge and model development. This leads to the observation that there is a clear practical demand, and that suitable software environments and some 3-D model components exist, but that t...
