I attended a HEC-RAS class given by the National Highway Institute, and I asked the instructors about this permanent ineffective areas business. They said that it was not applicable to steady-state modeling, and they would never recommend using it in a steady-state model. “Absolutely not” was one instructor’s reply.

The reason that permanent ineffective areas are included in RAS is for use in unsteady flow applications, when a model is crashing or otherwise acting squirrelly and you need to ‘put your thumb on it’ in order to make it resolve.

Straight from the horse’s mouth. 😉

Thanks y’all. When I next have time I may try to put the data into the data file itself instead of entering on the input screen.
