Effects of coriolis force and vegetation on jets

In the ocean, the direct effect of rotation on turbulence induced by an obstructed pattern should be quite negligible, because of its small scale. Nevertheless, the mean flow is modified by rotation and consequently the transport and spreading of turbulent kinetic energy and tracers by the mean flow is modified in a rotating frame (Godeferd & Moisy, 2015). Furthermore, the rotational effects are manifested through the development of Ekman boundary layers, effectively increasing friction. Hence, the interplay between rotation and turbulence due to obstacles deserves a thorough study. It is worth noting that obstructions for the jet discharge are not only representative of vegetated canopies,but also include mussels or oyster cultivation farms and mangrove forests in coastal regions. Therefore, the results of such experiments are expected to support environmental planning. Here, we report theexperimental setup and methods and preliminary results, focusing on the average velocity, vorticity and turbulence as observed under various experimental conditions
