Retrieval of the shape of the bottom surface of a channel when the free surface profile is given
Two-dimensional, steady, inviscid, irrotational, incompressible and gravity influenced free surface fluid flow in a channel, over a step of an unknown shape, was investigated when the free surface profile is given. A combination of the boundary integral method, the minimal height method and the application of a minimum plot procedure were employed in order to give an optimal solution to the problem.
