B.6 2D Junction Properties
| Name | Automatically assigned by 2D tool |
| X Coordinate | Horizontal location of the junction on the Study Area Map. If left blank, then the junction will not appear on the map. |
| Y Coordinate | Vertical location of the junction on the Study Area Map. If left blank, then the junction will not appear on the map. |
| Description | Click the ellipsis button (or press Enter) to edit an optional description of the junction. |
| Tag | Optional label used to categorize or classify the junction. |
| Invert Elevation | Invert elevation of the junction (feet or meters). |
| Maximum Depth | Maximum depth of junction (i.e., from ground surface to invert) (feet or meters). If zero, then the distance from the invert to the top of the highest connecting link will be used. |
| Initial Depth | Depth of water at the junction at the start of the simulation (feet or meters). |
| Surcharge Depth | Additional depth of water beyond the maximum depth that is allowed before the junction floods (feet or meters). This parameter can be used to simulate bolted manhole covers or force main connections. |
| Ponded area | Area occupied by pond water atop the junction after flooding occurs (sq. feet or sq. meters). If the Allow Ponding simulation option is turned on, a non-zero value of this parameter will allow ponded water to be stored and subsequently returned to the conveyance system when capacity exists. |
