EFFECTS OF MODELLING LONG AND SHORT CRESTED SEAS ON OVERTOPPING OF A LONG, VERTICAL-FACED BREAKWATER

Physical model tests have been conducted to examine wave penetration into Peterhead Bay on the North-east coast of Scotland as part of a proposed bay calming scheme. The modelling used both long and short crested waves. This paper describes the modelling work and describes key observations with regard to the observed wave conditions and ensuing vessel motions. The nature of the breakwater overtopping under different sea states and its effect on conditions behind the breakwater is also discussed.
