I'm trying to produce a time-area curve from a dem. After processing the dem using ArcHydro, I can create a Flow Length raster using the

Spatial Analyst Tools>Hydrology>Flow Length tool.
The attached jpg shows my project with distance "contours" that show the distance from the outlet in 100 ft intervals. I'd like to create a discrete raster like this that I can they use to work toward making a time-area curve from. The time-area curve would be used for estimating unit hydrographs (or unit graphs as they were first called by F. Snyder. See page 3 of this pdf
http://www.cccounty.us/DocumentView.aspx?DID=3709).


Can anyone direct me to a tool that will create a

discrete raster in equal intervals?
