Dear all,

i am working on twodimensional simulation modeling of unsteady overland flow. My govering equations are unsteady, non-linear parabolic Partial differential equations. For the interpolation in grid, i want to use cubic interpolation spline functions for interpolation to avoid the problem of stability, usually faced in explicit finite difference problems.

I want some help in getting the relevent references and souce code in fortran.
