Abstract: In nature, certain connected water bodies produce exchange gravimetric flows due to density differences, caused by variable concentrations of elements such as salt, sediment, or temperature. This study presents a brief description of these kinds of flows, including an experimental study of stratified exchange flows over a submarine sill. The hydrodynamic characterization has been developed using imaging analysis techniques and Particle Image Velocimetry in order to characterize the exchange gravimetric surface and the velocity fields. The results are compared with those obtained with a bidimensional numerical model that applies the finite volume method to the depth-averaged two-layer flow equations (Garcia, 2005).
