Extended Eddy Viscosity Concept for Wave Breaking in Boussinesq Type Models

Strybny, Jann / Zielke, Werner

This paper deals with the applicability of Boussinesq models in coastal areas in the direct vicinity of beaches and dykes. The improvement of an eddy viscosity concept with regard to modelling of the wave shape in surf zones is discussed. Furthermore the modelling of wave runup based on a newly developed Wet Slope is presented. It allows to determine the water volume associated with wave overtopping. Model calculations of laboratory tests and natural foreshore situations are carried out with the new strategies, and related issues are discussed.
