Abstract

Reflection and transmission characteristics of regular surface waves from a semi-circular, flexible breakwater, mounted on the bottom of a wave tank have been investigated experimentally. The main objective of this paper is to implement the continuous wavelet transform for digital time series in order to obtain the optimum conditions of the flexible breakwater for minimum wave transmission. The study is restricted to the two-dimensional cases of regular waves approaching normal to the obstacle, which is fixed and submerged in water of constant depth. The structure is filled with water. The important variables controlling the coefficients of reflection and transmission are the water depth, the internal pressure of the breakwater and the wavelength. It was found that using wavelet technique we can decompose a partial standing wave, which is established in front of an obstacle. This can be done using only one wave probe upstream of the model.
