Since gravity current is often observed in many natural systems and has kinetic energy that may favor the horizontal and vertical transport of sediment, we are investigating the horizontal transport of sediment and sediment resuspension caused by the propagation of gravity currents (e.g. Zordan et al., 2018; Adv. Water Resour. and Zordan et al., 2019; Earth Surf. Dynam.). We are analyzing the mixing efficiency and sediment resuspension through laboratory experiments (Fig 1) and numerical models.
