stroke time-history record that produced a water surface elevation time series conforming to the input 

 spectral representation and having significant height and peak period as specified. For regular waves, data 

 were collected at a rate of 50 Hz whereas irregular wave data were collected at a 20-Hz rate. Wave data 

 analysis was accomplished using a Vax 11-750 computer and software developed in-house^. Appendix A 

 gives a summary of the analysis package used. 



Prototype Condition 



76. The prototype data modeled in the tests described in this report were provided by Dr. H. Dette of 

 Technical University of Braunschweig and Dr. K. Uliczka of the University of Hannover in the Federal 

 Republic of Germany. These data resulted from prototype-scale tests conducted during 1985 in the large 

 wave tank (GroBer Wellenkanal or GWK) facility at the University of Hannover. The GWK has 

 dimensions of 324-m length, 5-m width, and 7-m depth and can generate regular and irregular waves at 

 prototype scale. The laboratory procedures used and some test results were presented at the International 



'Developed and modified by K. Turner, C. Long, and D. Ward, CERC, WES.
