Fluid-particle Coupling In Dilute
Suspension Releases

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-
