Flow Problems

Abstract
Since its first development by Kansa in 1990, the radial basis function collocation
method gains increasing interest recently. In this paper we apply this truly meshless
method to both 1-D and 2-D unsaturated ow problems, which are time-dependent
and highly nonlinear. Our numerical results demonstrate that the Kansa's method
is accurate and efficient to solve such nonlinear problems.
1 Introduction
Prediction of fluid movement in unsaturated soils is very important in soil science
and groundwater hydrology. The governing equation is the classical Richards
equation, which can be written in several forms, with either pressure head, moisture
content or mixing of them as the independent variable. In this paper, we consider
the pressure head based form:
