Tide Prediction for the Persian Gulf Coasts based on Harmonic Analysis

Abstract

This study employs two subprograms of the IOS package, including tidal height analysis and tidal height prediction, to predict tidal levels in multiple stations at the coastal area of the Persian Gulf for which the measured data on water levels are available. At first, the data measured in the stations under concern underwent harmonic analyses using the tidal height analysis subprogram of the IOS package. The analyses were performed in different phases for annual, semiyearly, trimonthly, and monthly periods. Next, working with the height prediction subprogram in the IOS package, the tidal levels in the stations were predicted separately for years wherein the measured data were accessible based on the results of various analyzes conducted in the previous phase (i.e., annual, semiyearly, trimonthly, and monthly periods). The investigations affirmed the performance of the method and its subprograms. Furthermore, the accuracy of forecasting made based on the annual harmonic analysis results was much higher than analyses conducted for other periods.
