Stormwatch UK Andy Bradbury   

Whats the problem? Unpredictable overtopping of beaches and structures Breaching barriers Seawalls fronted by beaches Eurotop will not predict overtopping in presence of beach

Wave induced flooding much worse than expected - events not forecast Forecasting “misses” for coastal flooding events all related to overtopping gravel beaches often with seawalls

Preliminary Objectives Identify how overtopping responses are related to beach profile and wave and water level conditions Is this systematic? Can we improve prediction methods?

Method- Observations of overtopping events Date Time Location

Method Application of data from regional coastal monitoring programmes Waves Tides Shoreline responses
