Design Scour Levels for Dune Revetments and Seawalls

A new method to determine design scour levels for dune revetments and seawalls is presented. The based on the thesis that toe a function of nearshore incident wave energy was calibrated with results from several moveable bed model studies covering large range scales. determines still water level datum defined at wave-breaking location. Therefore, incorporates many more parameters than those pertain existing methods including tidal stage, storm surge, setup, period, seabed slope. However, application not difficult methodology being sensitivity variations in values input examined limits their applicability are Recommendations further research given.
