Processes and products of turbidity currents entering soft muddy substrates
Jaco H. Baas et al., School of Ocean Sciences, Bangor University, Menai Bridge, Ynys Mn LL59 5AB, UK. Published online 17 Mar. 2014, http://dx.doi.org/10.1130/G35296.1.

New laboratory experiments reveal that cohesionless underwater landslides, called turbidity currents, are able to enter cohesive, "sticky," muddy seabeds without losing their shape. These intrabed currents are driven by bed shear stress exceeding bed cohesive strength and b
