2. 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.

5. 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
