B.5 Junction Properties
| Name | User-assigned junction name. |
| 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. |
| Inflows | Click the ellipsis button (or press Enter) to assign external direct, dry weather or RDII inflows to the junction. |
| Treatment | Click the ellipsis button (or press Enter) to edit a set of treatment functions for pollutants entering the node. |
| Invert El. | Invert elevation of the junction (feet or meters). |
| Max. 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. |
| *Active | Junctions in between 1D closed conduit will be active and junctions which are in between open 1D conduits will be inactive. In quasi 2D model, open channel will be represented by 2D mesh hence junctions fall within the open channel will become inactive. Only active features will be used for calculation. |
| *1D-2D Connectivity | Indicate the junctions which are connected to 2D junction through any structure. If “Yes” it is connected, if “No” it is not connected. |
*only applicable for GeoSWMM 2D Modeling
