A series of 36 unidirectional spectral waves was generated to determine the relationship between wave generator control signal and measured response at seven locations in teh model basin. Control signals consisted of combinations of three peak periods ranging from 1.0 to 2.0 sec, two zero-moment wave heights from 1 to 3 in., three spectral peak enhancement factors from 3.3 to 15, and two peak directions of 0 and -30 deg. Seven resistance or capacitance wave gages were centrally located 20 ft in front of the wave generator about its center line in a combination cross and 2-3-1-7 linear array. Descriptions of the spectral simulation and generation, time series and spectral analysis, frequency response, and wave grouping analysis are presented. Comparisons of predicted and measured peak period, zero-moment wave height, peak wave direction, frequency spectra, and directional spreading are presented and discussed. Frequency response and wave grouping statistics are calculated for each test case. This report consists of two volumes: Volume I consisting of the main test and Appendix A and Volume II consisting of Appendixes B-H.
