Channel-Physical
Manning's n is not a property of a channel but a property of the cross-section nodes along the channel. The cross-section defines the shape and other physical properties of the channel (except for length). The properties between two cross sections are interpolated. For more information, see "Cross Section—Physical" .
Channel-Physical Attributes
| Attribute | Description |
|---|---|
| Flow (Maximum User Defined) | Maximum flow allowed in link. Use 0.0 if not applicable. |
| Invert (Start) | The start, or upstream, invert of the currently highlighted element. |
| Set Invert to Stop Node | Sets the stop invert of the current element to the elevation of the stop node (downstream). Set this to False to enter a value for the elevation of the invert, or set this field to True to use the stop-node elevation. |
| Invert (Stop) | The stop, or downstream, invert of the currently highlighted element. |
| Slope | The difference between the start invert and stop invert divided by the length of the channel. This is a calculated results field and is not editable. |
