Initiation of motion: investigating sediment remobilization processes combining lab flume tank experiments, field measurement and numerical simulations
Describing sediment erosion is an important factor for the understanding of coastal processes. Erosion, i.e. the movement of single sediment grains, is initiated when the hydrodynamic driving force outweighs the grain resistance force. In addition to the flow field and the grain size and weight, other key parameters play a role in the initiation of motion: cohesive forces in between particles, stabilization or destabilization through biological activity, or so-called caging structures, i.e. textural induced structures of fine particles (clay) encompassing coarser sand grains (Le Hir et al. 2008, Mitchener and Torfs, 1996).
