Dam-break flows, whereby a material at rest within a lock is abruptly set into motion by the rapid removal of the lockgate, are of widespread interest, not just because of the generic unsteady flows they generate, but also of their direct application to environmental and engineering problems. In this seminar, I will present results that show how unsteady dam-break flows are arrested by a yield stress (visco-plastic materials) or by the action of drag (similar materials).
