Abstract EN
By constructing a radial basis function collocation method combined with a difference method, a two-dimensional mathematical model with boundary conditions of soil water movement under irrigation is proposed.
The nonlinear term is dealt with a difference method and the equation is solved using an implicit scheme.
In addition, the existence and uniqueness of the solution to the soil water movement equation are proven.
Numerical results show that the proposed method has high precision and is easier to use than traditional methods.
Moreover, the selection of parameter c plays an important role in guaranteeing calculation precision.
It lays the foundation for the numerical solutions to high-dimensional soil water movement equations.
