A compact representation of ocean wave directionality

Higgins, Alan L. / Seymour, Richard J. / Pawka, Steven S.

AbstractThe spectrum of the longshore component of shoreward directed momentum flux ( $S xy$ ) due to ocean waves, taken with the energy spectrum for the same wave field, is shown to provide a compact and useful representation of ocean wave directionality. Records of orthogonal surface slope components are demonstrated to yield an unbiased estimate of $S xy$ . One method for estimation of $S xy$ using this relationship is investigated. Error analysis provides means for optimal selection of measurement parameters. Experimental verification is provided from laboratory tests and from field comparison with a five-element linear array.
