Abstract

We develop asymptotic solutions for passive suspended sediment transport under a flood surge on a uniform slope. Our solutions provide predictions of the net scour under a surge, and simple estimates of the conditions under which it may ‘bulk up’ into a mud or debris flow, as well as illustrating their sensitivity to sediment entrainment rates.
