Abstract
Two computer models using the method of images to
determine the pressure amplitude and phase distribution in a
wedge shaped medium overlaying a fast fluid bottom were
studied. WEDGE used a source at infinity and was
constrained to upslope, on axis predictions, while CROSS
SLOPE, using a source at finite distance, made predictions
anywhere within the medium. Comparison of the two programs
suggest that an infinite source is not approached until the
source exceeds six hundred dump distances from the apex.
CROSS SLOPE predictions of pressure amplitude were in
agreement with experimental data obtained in the upslope
direction, and with sound fields similar to that described
by the theory of Buckingham but of much richer variety.
