Laboratory experiments simulating gravity-driven oceanographic coastal surface currents are described. In the natural environment such currents develop when estuarine fresh-water discharges into the ocean. Results from three complementing experimental studies are discussed and compared to a new geostrophic model. The first study was conducted in a small-scale (1m diameter) water-filled rotating tank. The other two studies were carried out at the large-scale Coriolis turntables at Grenoble (13m tank diameter) and Trondheim (5m tank diameter). Currents were generated by releasing buoyant fresh water continuously from a small source at the fluid surface. The height, width and length of the currents were studied as a function of the background rotation rate, the volumetric discharge rate at the source and the density difference between fresh and ambient fluid. The small-scale experiments and the Grenoble study focused on the simplest case of currents flowing along a vertical coastlines in an, effectively, infinitely deep ocean. The Trondheim study generalised these results by investigating how the dynamics are affected when the currents flow along inclined coastlines with different inclination angles with respect to the horizontal.
