Abstract

A new system for directional wave spectrum observation was developed by improving the Nationwide Ocean Wave information network for Ports and HArbourS (NOWPHAS). Either Doppler Type Wave Directional Meter (DWDM) or Wave Gauge Array System is adopted for wave observations. Directional spectra are estimated by EMLM method for DWDM and EMEP method for array system. For the convenience, the obtained directional spectra are expressed as the frequency banded wave heights and directions corresponding to the wave spectrum. Examples of annual statistics of the directional wave spectra at three typical NOWPHAS wave stations are introduced in this paper.
