Atlantic Coast Hindcast, Phase II: Wave Information 
Corson, W. D., et al., WIS Report 6 
Publication Date: March 1982 
Location: 33 stations along US Atlantic coast 
Period of Coverage: 1956-1975 
Contents: Using numerical hindcast techniques, significant wave data (height, 
period, and direction) are computed under deepwater and intermediate water 
depth conditions (continental shelf) for the 20-year interval, 1956-1975. The 
wave data are presented for 33 stations in 9 data products: 
(a) Seasonal percent occurrence tables. 
(b) Percent exceedance diagrams. 
(c) “Over duration table (duration of waves over a specific height). 
(d) "Under" duration table (duration of waves under a specific height). 
(e) Wave rose diagrams. 
(f) Height, period, direction histograms. 
(g) Return period diagrams. 
(h) Wave steepness diagrams. 
(i) Mean and largest wave-height tables. 
Description and method of use of the products are given in the report. 
The hindcast data are generated for deepwater and/or intermediate water 
depths where the geometry of continental shelf-shoreline configuration effects 
on waves become important. This report summarizes the results of Phase II of 
the Atlantic Coast Wave Information Study (ACWIS) conducted by the US Army 
Corps of Engineers. Since waves generated from tropical storms or hurricanes 
are excluded in the analyses, caution must be exercised when the data are 
applied for design or analysis purposes.
