Wave Data Analysis for Wave Energy Power in Namae Coast

Abstract

In order to install the wave power facilities in ocean and coastal area, it is very important to determine the properties of wave data. Discrete wavelet packet transform was applied in this study and was used as a tool to find out the basic properties of waves around Namae coast. Important features of hydrodynamic pressure such as frequency and magnitude were investigated in different observation time. Also the idea of measuring the noise rate was introduced and applied to both stationary and non-stationary time spans for the comparison. These methods would be useful to check the feasibility of wave energy extraction in various types of coasts.
