Experimental study of gravity currents moving over a sediment bed: suspension criterion and bed forms

In many natural settings, gravity currents flow over a mobile sediment bed as in fluvial outflows into lakes and reservoirs or in submarine canyons in coastal regions. We present experimental results which clarify the near-bed physical processes of sediment suspension, bed form Experimental study of...

Summary:In many natural settings, gravity currents flow over a mobile sediment bed as in fluvial outflows into lakes and reservoirs or in submarine canyons in coastal regions. We present experimental results which clarify the near-bed physical processes of sediment suspension, bed form Experimental study of gravity currents moving over a sediment bed with the measured wave length being in agreement with criteria given by Lapotre et al. (2017)[2]. An expression for the ripple growth is given in relation with the theoretical criteria of Charru et al. (2013)[3].
