channel gradient calculated as elevation of upstream segment endpoint/elevation of downstream segment endpoint/segment length.
Potential issues:
-streamlines not burned in to DEMs and elevations may be in or out of channel. potentially use nearest neighbor averaging to get a local endpoint elevation
