Abstract : A series of 111 monochromatic waves was generated to determine the relationship between the directional spectral wave generator control signal and the measured response at nine locations in the model basin. Control signals consisted of combinations of five wave periods ranging from 0.75 to 3.0 sec, five strokes from 1 to 11 in., and five wave directions from 0 to 60 deg. Nine resistance wire wave gages, spaced 10 ft apart within a 20 x 20 ft measurement area, were centrally located 10 ft in front of the wave generator about its center line. Comparisons are presented for measured versus predicted wave profile, period, height, and direction using linear, shallow water wave theory; these comparisons reflect the influence of water leakage around and under the wave paddle due to the portable design. Thus, future monochromatic wave control signals can be corrected to obtain the desired wave conditions at different locations within the basin.
