Περίληψη

A three-dimensional model called VH13D is developed using the vertical/horizontal integration (VHI) approach. The double-logarithmic velocity profile including both the surface and bottom sublayer characteristic lengths is employed to accurately evaluate the bottom shear stress and depth-averaged advective terms. The model is verified using analytical solutions and laboratory data for shear-induced countercurrent flows and is compared with other two- and three-dimensional circulation models in a simplified basin. It is demonstrated that the newly developed model improves the conventional two-dimensional depth-averaged and Quasi-3D models and provides a new approach to the three-dimensional wind-induced circulation model. It can efficiently simulate the wind-induced 3D current structure in lakes and estuaries under isothermal conditions.
