Look for instance at http://www.csit.fsu.edu/~burkardt/cpp_src/spline/spline.html
There is also a matlab version.
However, splines are sometimes hard to use for extrapolation purposes.
A simple inverse distance weighting method could also be used.
I think the most difficult part is the fusion and segregation within a network of canals?
Isn't there specialised software available (do you know http://www.dhisoftware.com).
HTH, cheers Wolfram
