JEts through VEegetation in a Rotating Basin

Contaminants, nutrients and sediment particles flow into inland and coastal water bodies often forming turbulent jets. The aim of the present project was to improve our capability to describe how jets interact with the environment in which they discharge, providing useful insights for possible mitigation of undesired and harmful impacts.

We focus on the case of a jet interacting with porous obstructions, mimicking rigid vegetation or marine farms, under the effect of the Coriolis force, as is often the case with large scale rivers discharging into the sea.

The experiments were carried out in the large scale facility 'Coriolis Platform' at LEGI Grenoble (FR), in the frame of the project "H+-CNRS-06-JEVERB" which received funding from the European Union's Horizon 2020 research and innovation program under grant agreement No. 654110, HYDRALAB+.

DETAILS ON DATA

The dataset here provided is the result of the PIV system acquisition, used in the project at LEGI. The data format is 3D Matlab file '.mat'. Each file includes the 3D matrices of the measured velocities with size (314 x 295 x 1999) and the coordinate reference (X,Y). The third dimension is relative to time. The PIV sampling frequency is 33 Hz.

The experiments and the procedure used for data processing are described in 'JEt interacting with VEgetation in a Rotating Basin', Proceedings of HYDRALAB+ Joint User Meeting, Bucharest, May 2019.
