RR621 Wave mapping in UK waters: Supporting document

This work updates the contour map of 50-year extreme significant wave height that is provided in OT 2001/010 (previously Section 11 of the Guidance Notes). The updated map, now presented for the 100 year return period, presents extreme significant wave height in UK waters derived from 373 data sets from the NEXTRA hindcast, calibrated against measured wave data and verified against established criteria.
