Abstract

It is apparent that thresholds of sediment stability are being surpassed in all subaqueous environments of the Mississippi River delta, from the interdistributary bays to the shelf edge. The factors that contribute to stress increase or strength reduction, leading to slope failure, are complex and clearly show that there are several different ways that critical strength/stress disequilibrium can be achieved. One characteristic of this very important method of sediment transport is that movements are sporadic or episodic. A stair-step geomorphic response generally results from these movements. Therefore, within any given deformational system such as a mudflow gully there is a nested array of geomorphic features, each with its own characteristics and stability thresholds.- from Authors
