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.
