Abstract

RELIABILITY OF LCS DETECTION DEPENDING ON HF-RADAR VELOCITY DATASET

Estimates of Lagrangian transport are important to provide reliable predictions of fate of pollutants in water bodies such as rivers, estuaries and coastal waters. The most recent approach is to understand the behavior of transport of contaminants in complex fluids by means of the detection of Lagrangian Coherent Structures (LCS). In the present work we aim at detecting the time evolution of LCS in the Gulf of Trieste evaluated on the basis of 2D surface velocity fields measured by means of coastal radars. The study is in the framework of the TOSCA research project (Tracking Oil Spills & Coastal Awareness network). Simulation of tracers trajectories have been developed in order to compare numerical results with drifter data released in the TOSCA experiment. Simulated and observed trajectories are consistent when radar data are available. They diverge significantly when, due to bad weather conditions, radar measurements are lacking.
