A Wave Transformation Model for Harbor Planning

The extended mild slope equation was solved using the Gaussian elimination method with partial pivoting and a special book-keeping procedure for simulating water wave refraction, diffraction, shoaling, reflection, and resonance. This finite difference model only requires sufficient hard disk space to handle realistic applications using small computers. Three verification tests were selected to demonstrate the performance of this numerical model. Comparisons between the model results and available experimental or analytical results indicated a satisfactory agreement. Because of the finite difference method and the direct approach to solve the governing equation, this model is simple to maintain. More importantly, it will be easy to upgrade with other processes in the future, e.g., bottom friction, tidal current influence, and spectrum waves. _________________________________________________________________________________________ Assoc.
