Abstract : A quantitative study was made of long-crested regular waves in the tenth-scale model of the Taylor Model Basin maneuvering basin. The eight wavemakers which constitute one short side of the basin were 'balanced' to produce uniform sinusoidal waves. The nature of the wave field, in time and space, was investigated for a variety of wave lengths and wave heights. It is demonstrated that a sufficiently large area of the tank remains homogeneously stationary to satisfy most test conditions. The observance of high-frequency reradiation from the sidewalls of the tank is discussed and remedial measures, based on experimentation, are suggested. It is shown that variable depth and removal of one side barrier do not materially affect wave propagation in the range of wave lengths and wave heights tested. The wave-absorbing beach was found to be highly effective. (Author)
