Abstract:A common application of joint probability in coastal engineering is to the simultaneous occurrence of a large wave height and a high still water level, and its consequent effect on sea defences. If two or more variables are either completely independent or completely dependent, then the joint probability calculations are relatively easy: however, this is rarely a good approximation in practice. In the past, the fitting and extrapolation of the dependence function between large wave heights and high water levels has involved complicated and/or subjective approaches unsuitable for use by non-specialists. We present a new approach to the joint probability of large wave heights and high water levels. The first part of the report written by HR Wallingford summarises the new developments and their range of applicability, and tests them against a number of field data sets. The second and longer part, written by Lancaster University gives full technical details of the new methods and a more rigorous comparison of alternative approaches based on synthetic sea state data. A shorter companion report TR 71 is intended for day-to-day application as a user manual for the associated JOIN-Sea joint probability software.
