The means by which fine sediment is transported across low-gradient shelves has been a topic of considerable debate. This work by Kämpf and Myrow addresses mechanisms involved in the cross-shelf transport of suspended mud through a numerical model. The results highlight the fundamental importance of gelling (a change from a water-supporting to sediment-supporting system) and the mechanism of gelling initiation to the dynamics of such flows. The numerical and conceptual insights improve understanding of suspended fluid-mud flows, and to the advanced description and prediction of such flows.
