Prediction of swash motion and run-up including the effects of swash interaction
(2005) In Coastal Engineering 52(3). p.285-302- Abstract
- Modifications to a model describing swash motion based on solutions to the non-linear shallow water equations were made to account for interaction between up-rush and back-wash at the still water shoreline and within the swash zone. Inputs to the model are wave heights and arrival times at the still water shoreline. The model was tested against wave groups representing idealized vessel-generated wave trains run in a small wave tank experiment. Accounting for swash interaction markedly improved results with respect to the maximum ran-up length for cases with rather gentle foreshore slopes (tan beta = 0.07). For the case with a steep foreshore slope (tan beta = 0.20) there was very little improvement compared to model results if swash... (More)

For the case with a steep foreshore slope (tan beta = 0.20) there was very little improvement compared to model results if swash interaction was not accounted for. In addition, an equation was developed to predict the onset and degree of swash interaction including the effects of bed friction. (Less)
