Abstract
An image model was used to predict the sound pressure
field everywhere within isospeed water overlying a sloping
absorbing bottom. All lengths scale with the dump distance,
which is the distance from the apex of the wedge to the
point where the depth is equal to the minimum uniform depth
that can support propagation of the lowest normal mode.
Measurements made in a laboratory tank with a 9.5° sand
bottom with density and speed of sound 2.0 and 1.1 times
those of water showed qualitative agreement with the
predictions of the model for receiver distances up to
10 dump distances from the apex and 50 dump distances along
the shore.
