Wave kinematics and fluid loading in irregular waves
Abstract
The ability of a Gaussian random wave model to describe wave kinematics in a natural sea for engineering applications was investigated. Surface elevation and horizontal and vertical velocities were measured simultaneously in a flume. Nine wave spectra, covering a wide range of sea states, were studied. Measurements and prediction agree well for unidirectional waves, and the influence of directional spreading in multidirectional seas can be accomodated. Model representations of the kinematics in the free surface zone, and predictions of the tails of statistical distributions of surface elevation and velocities must be improved.
