Abstract

The accurate prediction of ocean waves is crucial for various coastal and marine applications. In this paper, we focus on verifying the performance of the WaveWatch III (WW3) numerical wave model in simulating wave conditions using in situ buoy observations. The survey has been conducted to capture a comprehensive dataset of Acoustic Doppler Current Profiler (ADCP) measurements for one month period in the Karimunjawa Island area. The study area in this paper is determined in two areas, shallow and deep waters. To assess the WW3 model^s performance, a set of statistical metrics is conducted, including root mean square error (RMSE), bias, and correlation coefficients. The data obtained from the model simulations are compared against the ADCP measurements to determine the overall model skill and identify potential discrepancies. The results of this verification contribute to our understanding of the WW3 model^s suitability for predicting wave conditions in Karimunjawa Island and provide valuable insights into local wave behavior in shallow and deep waters to develop more reliable and efficient wave prediction systems for coastal management and marine operations.
