碩士 / 國立臺灣大學 / 土木工程學研究所 / 101 / In this thesis, a numerical model based on elliptic mild-slope equation is developed by using a special mesh-less numerical methods, namely, Modified Finite Point Method (MFPM) to simulate nearshore wave field.
Present methoduseaslocal polynomial function to formulateand to be solved with moving least square (MLS) approach. Computational points satisfy governing equation and boundary conditions by giving a weighting factor. Accuracy of numerical computations is improved.
The purpose of this research is to simulate breaking processes with energy dissipation term followed a rule obtained by experimental results. It is intended tosimulate the physical phenomena of water wave,transformation in the coastal areas, withreflection, refraction, diffraction, shoaling, and breaking. Present numerical results are compared with theoretical results, and experiment at measurements. Present model will be extended as a basis for further development of numerical models of nearshore currents and coastal sediments.
