20^ ABSTRACT (XJaatfnue mat rev9rm* aMe fl n e c eea a ry aaii Idenllly by block number) 



Digital wave analyses for 3 to 12 months of data from each of 11 U.S. 

 coastal gages are summarized and discussed. Water depths at tlie gage sites 

 were typically between 5 and 9 meters. The gage designs included step resist- 

 ance, continuous wire, pressure, and accelerometer buoy. The analysis for 

 each record included computation of the energy (or variance) spectrum and the 

 distribution function of sea-surface elevations. Parameters of the spectrum 

 and distribution function of sea-surface elevations were also computed.
