Abstract
Two-dimensional, steady, inviscid, irrotational, incompressible and gravity influ-
enced free surface fluid flow in a channel over a solid step of an unknown shape
has been investigated when the free surface profile is given. A combination of
the boundary integral technique and the minimal height method have been devel-
oped. By the application of an L—curve procedure, it is possible to predict the
best regularization parameter which can give an optimal solution to the problem.
1 Introduction
The problem of free surface fluid flow in a channel for which the
free surface profile is given, but the shape and position of the solid
bottom boundary are unknown a priori, is a field of research where
we have found no previous publications. The difficulty
