SHALLOW WATER PHENOMENA AND SCALE MODEL RESEARCH -- SOME EXPERIENCE FROM THE SSPA MARITIME DYNAMICS LABORATORY

After a brief survey of shallow water phenomena this paper presents some features of a new laboratory at SSPA in Gothenburg, designed with special attention to shallow water problems. The arrangement of height-adjusted wave flaps is discussed in the light of pre-design wave form experiments. In 1977, before the installation of the wave-generators and the wide-span multi-motion carriage, the basin was used for a variety of special studies of ship behaviour in shallow water, mostly by means of remotely controlled 5 m models. The description here includes some results of definite model trail maneuvres with the subsequent identification of hydrodynamic parameters, of the motion of a model past a short bank and a comparative simulation, of the additional squat experienced due to a local shallow, and of the wave-making of a model at near-to-critical speed.
