Evaluation of the Computation of Wave Direction with Three-Gage Arrays
Abstract
A description of the collection and analyses of data obtained with an array of five pressure sensors near Pt. Mugu, California, is presented. The 10 three-gage arrays possible with five gages are used to compare redundant values of the direction of wave propagation. The dependence of directional determination on array orientation relative to incident wave direction and wavelength at the array site is shown by calculations based on simulated narrow- banded wave trains. Directional results from the field study indicate the maximum accuracy of wave direction determinations with a three-gage arrays is on the order of + or - 20 degrees. This level of accuracy may be expected only for narrow-banded wave trains with periods longer than a lower limit determined at each location by array dimensions and water depth. The field study also indicates narrow-banded wave trains are frequent at this coastal location.
