Abstract

Three different numerical models for shallow water are applied to the Northern Adriatic to investigate wind-driven circulation phenomena. The main differences between the models are their vertical and time discretisation schemes, and the turbulence properties in the vertical, including the approximation of the bottom shear. In the first set of computations the models are run with identical assumptions concerning the vertical diffusion and the bottom friction, in order to find the basic level of agreement for the three models. A second series shows the overall circulation pattern in the Northern Adriatic obtained with model-specific turbulence properties. Two cases for the wind-induced surface shear-stress are considered: a constant wind forcing, and a variable surface (wind) shear-stress along the Northwest-Southeast axis of the basin.
