NUMERICAL WAVE FLUME SIMULATIONS OF SEAWALL OVERTOPPING

摘要

Realistic simulations of wave overtopping require numerical methods which are able accurately to simulate the shoaling, breaking and possible overturning of waves prior to their impact on the seawall. It is a further requirement that the simulation continues after impact, modelling the formation of the overtopping jet and the reflection of the wave. Research at Manchester Metropolitan University funded under the CLASH project has been working towards the development of such a numerical code. AMAZON-SC, provides a numerical wave flume based on the free surface capturing approach. This paper describes progress on this numerical method and it's application to various cases including: a test problem involving wave overtopping of a smooth sea-dike and wave overtopping at Samphire Hoe near Dover in the UK.
