Abstract

In this paper, a method has been developed for estimating the change of nearshore significant waves in response to long-term sea level rise, by extending the method proposed for regular waves by Townend in 1994. The relative changes in wavelength, refraction coefficient, shoaling coefficient, and wave height for random waves are presented as functions of the relative change in water depth. The changes in wavelength and refraction coefficient are calculated by using the significant wave period and principal wave direction in the formulas for regular waves. On the other hand, the changes in shoaling coefficient and wave height are calculated by using the formulas proposed for transformation of random waves in the nearshore area including the surf zone. The results are presented in the form of both formulas and graphs. In particular, the relative change in significant wave height is compared with the result for regular waves.
