The aim of this work was to develop a numerical program to decompose shallow water waves in order to properly analyze the wave induced forces on ocean vessels. The program was used in conjunction with waves genera ted in a model tank environment. The program identified the known waves in the tank and removed unwanted wave elevations created by imperfect model tank conditions. This will enable model testing and numerical modeling to more accurately analyze wave-ship interaction, thus improving design and prediction for vessels operating in shallow water regions. -- A literature review discusses the theories required in order to create a wave splitting tool as well as the theory used to simulate the theoretical set-down wave. The results we re validated in the time and frequency domain against a report from Maritime Research Institute Netherlands (MARIN) and the National Research Council (NRC) results, respectively. Result s we re generally acceptable; test cases became less favorable as wave frequency decreased. Potential future work on this topic includes using improved input wave data to compute wave-induced forces on vessels.
