Abstract
In this paper we shall present consistent scaling arguments leading to the development of various distinguished limit models for the study of particle suspension flows as produced in the classic lock-release experiments that are designed to illuminate the mechanisms of rarely observed submarine turbidity currents. We shall show that very dilute suspensions lead to a decoupling of fluid and particle dynamics and allow for a consistent description in terms of two-layer, shallow-water (hydraulic) theory, Moodie et aL [I] and Moodie [2], This class of models, when applied to the study of particle transport and deposition from bottom gravity currents produced by the sudden release of dilute, well-mixed fixed-volume suspensions have been relatively successful in predicting the experimentally observed long- t
