Sloping Seabed Profile

 		Previous pageNext page

Overview

If the sloping seabed option is invoked, a uniformly sloping seabed is modelled which passes through the global origin of co-ordinates. The seabed slope is specified in degrees, and a positive slope defines a seabed sloping upwards in the positive global Y direction, while a negative slope gives a seabed sloping in the opposite direction.

In addition to being able to specify the slope, elastic sloping seabed profiles can also be arbitrarily oriented about the global X axis. By default, the profile of a sloping seabed lies in the global XY plane. The orientation can be changed so that the sloping elastic seabed is rotated anti-clockwise about the global X axis by a user specified amount, ϕ, as shown in the figure below.
