홈페이지논문 초록 (Abstract)
A new, finite-element solution of linear water waves, which can be applied to a nonvertical bottom boundary, is introduced in this st udy. The present solution can be applied to regions in which the water depth gradually approaches zero, such as coastlines. To obtain this sol ution, the entire domain is divided into three subregions. In the up-wav e and down-wave subregions, analytical solutions are used. In the middl e region, which occupies most computational domain, the standard Ga lerkin finite-element method is applied. The introduced numerical method is compared with an analytical solution to show its validity.
