Presentation transcript:

Flood gates; closure based on alert levels derived from tidal surge predictions But the driving force behind this research has its roots in much less stormy conditions. Seaton, 24 October 2006, flood gates not closed because Hs did not reach threshold. Anecdotal reports of very long waves surging up the beach. Seaton Beach, Cornwall

Problems A not insignificant number of coastal flooding events have occurred when not predicted Those flooding events have occurred in what might be considered “normal” wave conditions i.e. not storms So, the wave conditions were clearly important
