Abstract
Objectives(s) The wave setup can contribute significantly to abnormal water level during severe storm. So accurate prediction of the wave setup is essential in many coastal engineering projects. It is needed to develop a practical wave setup prediction system that can be conveniently used together with storm surge model for operational forecasting and hindcasting of total water level induced by storm along all the coast of Korea. Material & Method(s) Two types of wave setup prediction systems were established for all the major coastal area of Korea: one by estimating coastal wave condition and then wave setup by using empirical relationship with representative parameters of beach and wave conditions and the other by means of numerical models to estimate surf zone wave, current and wave setup using offshore boundary conditions. For the coastal area with complicated bathymetry where the empirical relationships obtained from field experiment data from plain beaches are not applicable, the new relationships were formulated by means of numerical experiments using the models validated with field experimental data for simple cases. The wave condition that are needed in both prediction methods is also produced by two methods: one by means of simple fast wave transformation using pre-calculated data base and the other using shallow water transformation model considering the detailed interaction among the coastal parameters. Result(s) Wave setup prediction system was established and tested for major coast of Korea and was shown to function reasonably well. Wave setup climate was produced for all the coast of Korea appling the simple prediction method using the long-term continuous wave simulation data for all the coastal waters of Korea. Conclusion(s) The established wave setup prediction system can be used in operational storm surge prediction as well as hindcasting water level to produce the extreme water level along the coat of Korea.
