Erosion of a model cohesive seabed in wave-current flume

Résumé

This study proposes a novel approach for studying effect of rheological properties of cohesive seabed on erosion physical processes under waves and currents. Herein we completely control and adjust rheological parameters by using a model sediment or Synthetic Transparent Cohesive Seabed (STCS) and hydrodynamic forcing in small (15x30 cm2 section) laboratory wave flume. STCS, introduced by Pouv (Pouv, et al. 2014) and Tarhini (Tarhini, Bellanger et Jarny 2016), is manufactured from mixture of synthetic polymers and clay having qualitative rheological similarities to natural muddy seabed.
