修改的模型描述的非线性浅水方程的解决方案的基础上的斜流运动进行了帐户之间的相互作用，在静水海岸线和斜流区内的上冲和反洗。模型的输入是波高和到达静水海岸线的时间。该模型进行了测试，对波组代表理想化的船舶产生的波列运行在一个小波浪水槽实验。考虑到冲流相互作用，对于前滨坡度相当平缓的情况，最大助跑长度的结果明显改善（tanβ=0.07）。对于具有陡峭前滨坡度（tanβ=0.20）的情况，如果不考虑冲流相互作用，则与模型结果相比，改善非常小。此外，一个方程，包括床摩擦的影响，预测的发病率和程度的冲相互作用。
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 run-up length for cases with rather gentle foreshore slopes (tanβ=0.07). For the case with a steep foreshore slope (tanβ=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.
