Abstract
Two-dimensional hydraulic and numerical experiments have been performed for clarifying the wind-induced upwelling and mixing phenomena in a two-layered stratified flow system exposed to wind stresses at the water surface. Both experiments make clear that the classification of four flow regimes proposed by Spigel & Imberger (1980) is a good agreement with both experimental results in terms of Wedderburn number and that upwelling phenomena of density interface occur only in the range of We less than 4.0. Both experiments are also carried out in the flume with an open downstream boundary in order to examine the phenomena appeared in semi-enclosed bay such as Tokyo Bay. The numerical experiments are quantitatively confirmed to show a good agreement with the results of hydraulic experiments.
