A pragmatic approach for the numerical prediction of meteotsunamis in Ciutadella harbour (Balearic Islands)

摘要

Ciutadella (Menorca, Balearic Islands, Spain) is well known for the large amplitude seiches of about 10.5 min period registered in its long and narrow inlet, especially during the warm season. This phenomenon, locally referred to as "rissaga", might reach extreme wave heights (in the range 1.5 - 4 m) with a recurrence of only a few years, leading to damaging consequences in the port activities and moored vessels. The provision of as accurate as possible predictions of the rissaga risk, hours or days ahead, appears as a crucial element in helping to mitigate these consequences.
