碩士 / 國立臺灣海洋大學 / 河海工程學系 / 92 / With the promotion of the concepts of marine environment protection, such as ecological conservation and water purifying, many permeable structures are constructed popularly in these years. Therefore, the main purpose of this thesis is to investigate the scattering problem of water waves by ecological breakwater with internal partition. Nine different geometrical configurations of the ecological breakwater are considered by using the program based on the composite boundary element method, including no internal plates, horizontal impermeable plate, horizontal porous plate, horizontal impermeable & vertical porous plates, horizontal & vertical porous plates, upper vertical porous & other impermeable plates, lower vertical porous & other impermeable plates, upper vertical impermeable & other porous plates, and lower vertical impermeable & other porous plates. The numerical results, concerning the effects of submerged depths of the internal horizontal plate and porous coefficients of internal plates as well as the reflection, transmission and energy-loss coefficients, are presented. Hopefully, the numerical results of this thesis could offer applications & designs for harbor, costal ecology engineering and some consultations for the related scholastic research.
