Decomposition of Incident and Reflected Waves Using a Single Moving Wave Gauge

Abstract

A new method of splitting regular or irregular waves into reflected and transmitted waves using a single moving wave gauge was developed. Water surface elevations at several locations and times were measured with one wave gauge, and the incident and reflected wave heights were obtained using the fast Fourier transformation and the least-square method. The accuracy and efficiency of the proposed method were validated using numerical tests for regular and irregular waves. Good agreement was observed between the target and the prediction values.
