Abstract

In this paper wind-driven horizontal and vertical large scale circulations in shallow lakes are analysed

As an improved approximation of the external forcing field, the wind speed acceleration due to the abrupt reduction in the surface roughness between the land and the water is quantified along the fetch using a semi-empirical approach which allows the identification of the aerodynamic features and hydrodynamic effects of an Internal Boundary Layer (IBL) growing within the bottom of the atmospheric boundary layer

The consequent fetch-dependence of the wind speed and corresponding wind shear stresses on the lake surface causes the appearance of a wind stress curl, which is responsible, together with changes in bathymetry, for causing strong horizontal circulations. The effects of wind speed changes on the wind-driven flow patterns are analysed both analytically and numerically, showing the need to take these changes into account in order to correctly predict wind-induced water currents in shallow basins
