WAVE-TANK STUDY OF INTERNAL WAVES.

Abstract

Internal waves, generated in an approximate two-layer system of miscible fluids by flow over a submarine ridge, were examined. The investigation was conducted in a wave tank 3.0 m long and 0.3 m wide in which total water depth varied between 7.3 cm and 15.2 cm. The observed motions were compared with those predicted by internal wave theory. Observed phase velocities differed from the theoretical phase velocities in all cases, with a maximum difference in one case of 44% of theoretical value. The discrepancies may be due either to the superposition of the observed progressive wave on a standing wave or to the observation of non-conserved wave crests in a dispersive medium. However, observed phase velocities did decrease in magnitude with a decreasing layer density difference as predicted by theory. (Author)
