In the study reported depth profiles and tip velocities were measured for a series of unsteady mud flows generated in a laboratory flume using a dam break scenario. Observation of a wide range of mud flow conditions was achieved through variations of the flume slope, initial fluid depth in the reservoir, and concentration of solid particles. Rheological measurements on samples of mud from most of the flume tests were carried out promptly at the end of each experiment. These rheological data enabled the development of a momentum transport relationship that describes the flow of fluid mud.
