Rivers are highly lossy (lots of friction and turbulence) so an assumption of inviscid flow seems very questionable.You probably want to use a constant velocity and assume that the potential energy from going down hill goes directly to viscous dissipation. Also, the concept that you've drawn from the heat equation is correct, but the eqn. itself is inadequate for flowing media (needs advection). | |

| Feb 11, 2015 at 20:24 | comment | added | Sparkler | @DanielSank, the "sub-questions" I listed are meant to describe the main questions -- they are not separate questions but rather different aspects of the same thing, and I believe it would be more beneficial for everyone to have it all "under one roof" in this case. | |
