What about a spline interpolation? 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
