We derived analytical solutions for long waves on a circular island with combined topographies. The inner region is a circular island o n a flat bottom and the outer region is a cylindrical island on a shoal . The solution for the circular island on aflat bottom was developed previously by Jung et al. (2010) [13]. The solution for the cylindr ical island on a shoal was developed in the present study using the meth ods of separation of variables, Taylor series expansion, and Frobenius series. The present solution for the cylindrical island on a shoal was verified by comparing with previous solutions which was developed for limited cases. Also, some cases were investigated with different values of wave period, shoal vertex level, and power of the radius. The solutions for two different types of real islands were obtained using the solution for the combined topographies. The present solutio n for the combined topographies can be applied more accurately to the real island than the previous solution for the single bottom topogra phy. (C) 2011 Elsevier B.V.
