For heterogenous input data I'd try the nn algorithm in nnbathy, through r.surf.nnbathy (http://grass.osgeo.org/wiki/Addons#r.surf.nnbathy).
It is great for sparse points, but for contour lines + hydrological modeling it is not the best. See nn valley staircase effect in http://grass.osgeo.org/wiki/Contour_lines_to_DEM
Interpolating from contour lines has always been a nightmare for me :). What is the best approach in your opinion?
