Lauren-
Not directly. However, you could “build” the cross section incrementally in the HD/Uniform Flow calculator in RAS (Run…Hydraulic Design Functions, Type…Uniform Flow). With each incremental addition of a station elevation point, run the uniform flow computations to solve for discharge. Save the station and the resulting discharge in an excel table. As you “build” the cross section you should have a cumulative discharge going across the cross section. Then don’t forget to divide all of those discharges by the square root of the energy slope to get conveyance. I haven’t tried this myself, but in principle it should work. If you already have the cross section in RAS, it would be easier to “deconstruct” it as you collect normal discharges, rather than build it (i.e. compute normal discharge, then remove the last sta-el pair from the table then repeat).
