Here’s an example of the output from the 2-D model for the Easton Reach. It is for depth only at a flow of 300 cfs. Understand that there are maps like this for all of the simulated flows. Also, these maps are generated for water velocity, Froude number (which is the ratio between kinetic and potential energy, often used as an index of turbulence), and water surface elevations.

The next step is to get these maps to tell you something about habitat availability. You do that through the application of the HSC which translate the hydraulic elements of streams in to indices of habitat quality. I should mention that the determination of suitable habitat was based on water depth and velocity only. It would have been nice to have substrate in there, particularly for spawning, but these floodplain reaches were between 5-10 kilometers long and it apparently was not practical to collect detailed data on the substrate composition.
