I am now to the point where I have a stream, banks, xsections, and bridges/culverts. I have two questions really.
I know I can download a land use map from ArcGIS, but have yet to figure out how to combine that with manning's equations. Can anybody offer some pointers.
The other problem I have is when exporting the model to HEC RAS it just makes the stream a straight line starting at 0,0. It doesn't geo reference it. It keeps distance and elevations, but not the actual x/y data. Not sure how that happens either, but would love a few pointers.
[EDIT]
Deleted all the files in that folder, ran the RAS Geometry again, and it exported just fine. It looks like it was trying to export a random line as the centerline. Would still love help with the land use though
