Kim, T.R., Kang, T.S., Chun, J. and Hong, S.J., 2013. Development of system to countermeasure large swells on the East coast of Korea.

A recent increase in damages from large swells hitting the east coast of Korea has necessitated a system warning people on the shore. This paper introduces the development of a large swell warning system in the east coast of Korea using a wave numerical model in unstructured grids with offshore wave measurement data at the boundary as input conditions. Rapid warning and easy operation by nonprofessional operators in local government on the coast were important considerations. The system built a scenario DB of all the cases of swell hits to the coast, in terms of time and location, related to their detection at an offshore wave measurement site. Once the swell propagation field DB is constructed, whenever a dangerous swell is detected at the offshore site, the time and location for the dangerous shore hit by this swell is immediately picked from the DB and can be used for warning people by blocking the approach to the shore, siren, broadcasting or APP service in the smartphone.
