| Abstract: | The aim of the present work is to analyze in detail flow motions within the swash zone and define suitable Shoreline Boundary Conditions for the longshore flow for wave-averaged circulation models. An analytical solution for the longshore motion representing the drift velocity of the whole swash zone water mass is found. A complete set of Shoreline Boundary Conditions is obtained on the basis of fully-numerical solutions of the Nonlinear Shallow Water Equations. The main focus of the work is to clarify the structure of the Shoreline Boundary Conditions for the longshore flow but care has also been placed on their derivation and assessment from the numerical solutions. The latter have been obtained on the basis of a fairly broad range of input wave conditions. | |
