Balance Of A Dense Volume Of Fluid

Abstract
The steady-state propagation of cold domes of dense fluid lying beneath a
layer of less dense fluid and overlying a sloping bottom have been studied
previously by Nof [I]. Such research is important in improving the under-
standing of heat and mass transport in the oceans, and much of the present-
day understanding relies on the assumption that the flow is in geostrophic
balance. Such an assumption is not valid either when inertial effects in the
flow dominate, or when the flow is near the equator.
The research presented concerns the initial release problem of a finite
volume of dense fluid underlying a deeper layer of less dense fluid. The
flow is modelled by the shallow-water equations in three spatial dimensions
which are expressed as a system of nonlinear hyperbolic conservation laws.
Numerical solutions are achi
