| Active | If true, then the reach will control the underlying reach's Manning number. |
| DesignFactor | Current value of the design factor |
| Diameter | The current diameter of the underlying circular reach (the diameter of the cross section in the first h-grid point). |
| InitialDesignFactor | The control of Manning number is indirect in that the control acts on a factor that is multiplied onto the Manning number (the actual Manning number is the original Manning nubmer times this factor). InitialDesignFactor controls the value of the factor at the beginning of the simulation. |
| MaxManning | Maximum value of the manning number |
| MinManning | Minimum value of the manning number |
| OriginalDiameter | Original diameter of the reach (really of the first (upstream) cross section) |
| ReachId | ID of the underlying EngineReach |
| Results | List of results from previous simulations |
| UpstreamNodeId | ID of the upstream node |
