On the Effect of Barotropic Current Fluctuations on the Two-Layer Transport Capacity of a Constriction

Abstract

A simple theory shows that the two-layer transport capacity of a constriction may be increased considerably by barotropic current fluctuations. This is confirmed by laboratory experiments. The effect may be of great importance for the deep-water renewal process in some sill fjords and for the hydrographic conditions in some overmixed estuaries.
