Description: Technical note
Introduction: WIS has supplied wave climate information at locations along the U S Atlantic coast based on the 20 year period 1956-1975, (Corson, et. al., 1981), (Corson, et. al., 1982), (Jensen, 1983). This information meets a critical need for wave information in coastal engineering studies. Wave measurements made by the National Oceanic and Atmospheric Administration (NOAA) and Corps of Engineers (CE) during the 1980's makes a better verification of the WIS results possible by comparing statistics for the two different time periods, for example (Miller and Jensen, 1990), and (Hagerman, personal communication, b1988). These comparisons (both for the North Carolina coast) indicated that the distribution of hindcast wave heights and periods differed from the distributions of measured data. The directional distribution of wave energy from a year's measurements by a directional buoy at Kingsbay, GA was compared to WIS results by CERC. Again differences were noted. Others,(Weggel, Douglass, and Tunnell,. 1988) also noted "unrealistic" behavior in some of the WIS results. A one year hindcast for the Atlantic was done for 1988, using as nearly the same technique and model as in the original hindcast, (Lin and Wang, 1990). Hindcast results were compared to NOAA buoy and nearshore CE wave gage measurements. Heights compared well, but periods and directions differed more significantly. The present version of the WIS wave model WISWAVE improved the comparisons. These comparisons led to the decision to revise the WIS information for the Atlantic coast for the period 1956-1975. This CETN briefly summarizes the procedure used in the revision, verification of the model prior to and after the calculations, and available results. A more detailed discussion and the tabular summary of results will be available in WIS Report 30, (Hubertz, Brooks, Brandon, and Tracy, in preparation).
