Atlantic Coast Hindcast, Shallow-—Water, Significant Wave Information 
Jensen, Robert E., WIS Report 9 
Publication Date: January 1983 
Location: 166 stations along the US Atlantic coast 
Period of Coverage: 1956-1975 
Contents: Using a numerical transformation technique, significant wave data 
are computed for the 20-year interval, 1956-1975, for the US Atlantic coast. 
The hindcast wave data are presented for 166 stations in six data products: 
(a) Geographical variation in the wave climate (including mean wave 
height, period, and direction). 
(b) Twenty-year percent occurrence tables. 
(c) Wave rose diagrams. 
(d) Mean and largest wave-height tables. 
(e) Return period table (including wave parameter statistics). 
(f) "Over" duration tables (duration of waves over a specific wave 
height). 
Description and method of use of the products are given in the report. 
This report presents the results of Phase III of the Atlantic Coast Wave 
Information Study (ACWIS) conducted by the US Army Corps of Engineers. The 
hindcast data are generated by the transformation of ACWIS Phase II wave data 
into shallow water where the depth is 10 m. Furthermore, straight and paral- 
lel bottom contours have been assumed in the analyses. Waves generated from 
tropical storms (hurricanes) are excluded in the study.

Additional Information: A computer-based system (SEAS) has been designed 
to provide direct access to the hindcast wave 
data produced by the ACWIS. The use of SEAS 
is described in the report entitled '"Sea-State 
Engineering Analyses System (SEAS)," by D. S. 
Ragsdale, WIS Report 10, August 1983. For more
