Miyazaki Sun Marina has been suffering from a sedimentation problem at the entrance of its navigation channel. One of the reasons of this problem is assumed a sediment transport from the north side of the marina. In this study, two sets of data are used to investigate the sedimentation problem. One is a set of long-term depth data that has been measured inside the Miyazaki Port annually from 2008 to 2018. The other is also a set of short-term depth data that has been measured along the marina navigation channel every day from 2018 to 2020. Characteristics of depth change obtained from those data are investigated based on a linear regression analysis. This study suggests an area that causes the sedimentation problem in the marina navigation channel.
