Thank you!! Great explanation!!

[@elispot17]

How do you run the model using the diffussion equation in Hec Ras?

In the unsteady state plan editor select options, and then select computations options and tolerances. In the 2D tab you will notice RAS has by default, the Diffusive wave equations selected.
