Quasi 3-D Modeling of Nearshore Hydrodynamics
Abstract
In this thesis a depth integrated, shortwave averaged nearshore circulation model, called SHORECIRC, is developed, which includes the current current and current wave interactions over depth. This model belongs to the class of quasi 3D models, which combine the effect of the vertical structure with the simplicity of 2DH models. The present model uses semi-analytical solutions for the 3D current profiles in combination with a numerical solution of the depth integrated 2D horizontal equations. The goal of this model is to gain an enhanced prediction and analysis capability for nearshore circulation on any bathymetry and under any hydrodynamical condition. The current current, current wave induced dispersion mechanism has previously been found to significantly augment the lateral turbulent mixing in the case of a steady, uniform longshore current on a straight coast. In this thesis, the generalized quasi 3-D continuity and momentum equations governing nearshore circulation are presented. These equations are based on the complete Reynolds equations with as few additional assumptions as possible.
