Abstract : The analogy between small amplitude wave propagation in shallow water and acoustic wave propagation in a uniform medium is discussed. A simplified first order theory is derived, based upon space-time techniques, in order to predict the magnitudes of the transmitted and reflected waves arising due to the incident wave encountering a small area change. Theoretical calculations agree favorably with experimental results. Photographs obtained from motion pictures of the unsteady phenomena are also presented. (Author)
