Pemodelan Gelombang di Perairan Jambi

Abstract

Waves spread from deep water to shallow water. Wave propagation is a form of disturbance in a medium, in this case the air medium. One form of disturbance is wind friction. So the direction and speed of the wind can be used to determine the height and period of the waves produced. The SPM 1984 method is used in this analysis to determine the height and period of significant waves in shallow waters, especially Jambi waters. Wind data used to estimate high temperatures and wave periods were obtained from the National Oceanic and Atmospheric Administration (NOAA) for 10 years (2010-2019). Duration correction is carried out to obtain hourly average wind data. Next, carry out stability corrections and determine the value of the wind pressure factor, where this value, effective retrieval, and water depth are used to obtain significant wave height and period values. The analysis results show that the significant wave height is 5,739 with a return period of 50 years
