Abstract:

This study aims to determine the vertical pressure distribution of waves when tides occur simultaneously with ocean waves obtained by wave forecasting based on wind data. Changes in water level elevation due to tides coupled with waves can impact the occurrence of abrasion when the wave energy is large. The research was located in the Manembonembo Girian beach Bitung of North Sulawesi. It begins with data collection in the form of bathimetric data, tidal data, and wave forecasting based on wind data at the research site. Tidal data is based on data from Lantamal VIII Manado; wind data is sourced from Bitung BMKG data. The pressure obtained on the wave is the summation of the hydrostatic pressure and the hydrodynamic pressure. The results of the simulations in the study showed that tidal waves working together with waves obtained from wave forecasting based on wind data would increase the magnitude of the wave's vertical pressure distribution. Based on the case of a comparison between wind wave and wind combination tidal, the wave pressure was obtained at 11.662 t in the crest and 2.607t in the trough of wave affected by wind, and 45.34t in the crest and 2.918t in the trough of wave combination tidal. It indicates that the tide can enlarge the vertical pressure distribution of waves.
