Abstract: In port planning, one of the important aspects to consider is determination of harbor location and its orientation. The purpose of this study is to analyze the location and orientation of the harbor due to waves conditions at west of Borneo. The previous work has focused on the less dominant wind-induced water levels (waves) which are comparatively important but more challenging for accurate predictions. It addresses the application of ocean-atmosphere coupling through non-tidal barotropic numerical modelling and studies the cause and effect relations between regional meteorological features and observed water levels at different scales. It has previously been shown that a fine-resolution grid which is nested online in the basin scale model, is able to capture the trend of the observation. A basin-scale model is constructed to be able to properly model the waves which are caused by wind and pressure fields in the open ocean based on ECMWF numerical weather forcing conditions. The present work focuses on statistical analysis of 5 (five) years simulated waves dataset which is carried out to find the waves distribution around the area of interest. The study indicates the benefits of the systematic approach in which long term statistical analysis can be effectively carried out for port planning purposes.
