Influence of Global Greenhouse Effect on Seawall Wave Overtopping at Waterfront

Abstract

In this paper, the following two subjects are investigated.
1) Influence to global greenhouse effect on typhoon action.
2) Increase of wave overtopping rate due to the combined effects of mean sea level rise, intensified typhoon, and beach erosion.
The main conclusions obtained are
1) The possibility of intensifying a typhoon due to mean sea level rise can not be neglected in the treatment of greenhouse effect.
2) Coastal profile eroded by magnified waves can be predicted by eqs.(5), (6), and (7).
3) Rate of wave overtopping is considerably increased by the effect of mean sea level rise and is further increased by beach erosion. the effect of intensifying a typhoon on wave overtopping rate is remarkably large.
