A classification based on wave steepness, height and period, allowed swell and wave growth situations to be distinguished

An intercomparison of wave measurements from in-situ instruments and radars in SCAWVEX demonstrated the need to account for currents when estimating waves from bottom pressures. Preliminary analyses of X-band radar wave data suggested that useful estimates water depth in the area just outside the surf zone, difficult to survey by other means, might be possible, though a better transfer function, relating wave height to radar return, and improved treatment of dispersion including currents were required.
