I would recommend drawing a separate “way” for the highway. I imagine that the route taken by vehicles or people walking is a few meters off of the center of the waterway, and perhaps a little straighter. If you are coarsest tracing the waterway and road, then the two ways might share most of their nodes.
Drawing separate ways for highway and waterway but sharing the same nodes will also lead to problems - there's no way that data consumers will know that this highway is also a waterway. If you're going to do that then you'll need to add some other tag to the highway to say "you may get wet".
Highways and waterways using exactly the same route is pretty common where I am in the UK - they're called "long fords" (we don't have many wadis), and a ford=yes tag allows renderers to process them. I'd imagine for wadis some other tag (maybe some sort of "hazard"?) would be more appropriate, but it needs something.
