New channel following existing topography profile in 2D

[DMoran]

I am modelling a surface in 2D and want to add in a V-shaped channel 1m deep that follows the profile of the existing ground topography. Is there a way to set up one XS and subtract it from the surface along a river centerline? Or what is the best way of completing this?
