Abstract

We discuss results obtained from laboratory simulations of gravity-driven coastal surface currents produced when estuarine fresh-water discharges into the ocean. The present set of experiments was conducted using the large-scale rotating Coriolis tank at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway. The goal of the experiments was to begin studying the effects arising when currents interact with the bottom topography. As a consequence of the experimental data collected we became able to extend our geostrophic model (Thomas & Linden 2007, J. Fluid Mech., 578, pp. 35-65) developed for currents flowing along vertical walls to include the effects of the bottom topography.
