ANALISIS TINGGI GELOMBANG SIGNIFIKAN BERDASARKAN MODEL WAVEWATCH-III DI PANTAI ALAU-ALAU , KELURAHAN WAY URANG, KALIANDA, LAMPUNG SELATAN.
2020
Alau-Alau Beach is a coastal area that used for tourism and fishery such as boat lift net. The estimation of wave height is very useful to avoid events or accidents that potentially happened in the beach. The aims of this study are to analyze the significant wave height in the Alau-Alau Beach area, Way Urang Village, Kalianda, South Lampung and to analyze the accuracy of the Wavewatch-III BMKG (Climatology and Geophysics Meteorological Agency) with field data. Data of Wavewatch-III Model was visualized by using GrADS software, then compared it with field measurement data that was carried out for 7 days, from 20-26 November 2019. RMSE (Root Mean Square Error) was used in seing the accuracy of the model. The results from the field measurement showed that significant wave heights at Alau-Alau Beach ranged from 0.082 to 0.405 meters. The significant wave height from the Wavewatch-III model ranged from 0.027 to 0.118 meters. The results from the RMSE Wavewatch-III model on field data was 0.28.
