On the mechanics of the deep-water flow in the Bornholm Channel

Abstract

A model for stationary and longitudinally homogeneous 2-layer rotating canal flow subject to friction is proposed for the deep-water flow in the Bornholm Channel. Using parameter values estimated from the results of a field survey carried out in conjunction with a long term program for monitoring the inflow of high-saline water to the Baltic, diagnostic calculations for the position of the pycnocline have been performed. The results correspond to an encouraging degree to those observed in nature and indicate the existence ofa frictional coupling between the down-and cross-stream pressure gradients in deep-water.
