Pohang New Port, located on the east coast of Korea, has suffered from serious downtime problems. Infragravity waves incorporated with swells or locally-generated wind waves are presumed as an important factor for affecting the downtime, but little investigation has been made to estimate the infragravity waves inside the harbor. In this study, fundamental characteristics of the infragravity waves were investigated by utilizing the wave monitoring data collected inside and outside Pohang New Port as well as the downtime occurrence records. In order to find a relationship between infragravity and gravity waves, regression analysis was conducted for the wave records obtained at each measurement station. To complement the analysis, additional regression was also made between the heights of infragravity waves inside the harbor and those of gravity waves outside the harbor. This provides a better correlation of the quantities, indicating possible use of the information for estimating infragravity waves.
