Studies into the structure and motion of density currents. September 1983.

Abstract

Describes in detail the frontal structure of the head of a density current and the nature of the layer behind the head. The descriptions are based on the results of laboratory experiments in which a dense saline layer flowed beneath a buoyant one in a water tunnel. Data are presented on the volume and density fluxes, frontal celerity and the nature of the dissipative region behind the head of a range of fractional depths. The form drag associated with the head of a density current is alson comp[uted.
