Document how results pfc vs r.pfc are calculated for open channels

in the long plots we ask for two capacities, we get pfc vs r.pfc for pipes they are the same , but for open channels such a trapezoidal they are different. there seems to be no literature on this.

    PFC is just full pipe capacity, and it is not part of the ICM InfoWorks solution. It is a reference value that users can easily understand as it is based on Manning's equation. Regarding your question, it is probably a case where the PFC calcuated on the link grid uses a different cross-sectional area than the cross-sectional area during the simulation.
