Study of ocean wave characteristics in Lembasada, Donggala District, Central Sulawesi

This study discusses the characteristics of ocean waves in Lembasada waters, Banawa Selatan, Donggala District, Central Sulawesi. The characteristics of ocean waves are related to significant wave height and peak period. This study was conducted by utilizing the reanalysis data from ECMWF 1996, 2008, 2015 and bathymetry data from Seamap. The analysis is done by observing seasonal variability in the presence of ENSO and ordinary effects. Based on the results obtained, indicating that in the normal year without any ENSO influence, the wave height in these waters is likely to follow a seasonal pattern, with significant wave height lower than the ENSO effect.
