Renumber Interconnected Junctions Command

The Renumber Interconnected Junctions command allows the user to automatically renumber routing junctions and connected routing reaches along a defined flow path.

Follow the steps below to use the Renumber Interconnected Junctions command:

  1. From the Input ribbon menu, click the Routing Junctions dropdown menu and then select the Renumber Interconnected Junctions.
    Renumber Interconnected Junctions command
  2. The Renumber Interconnected Junctions dialog box will be displayed.
    Renumber Interconnected Junctions dialog box

The following sections describe the Renumber Interconnected Junctions command and how to interact with the above dialog box.

Selecting Reaches

The Select Reaches panel allows the user to select reaches that define the flow path.

Selecting Multiple (Interconnected) Reaches

The Select Multiple (Interconnected) Reaches section is used to sequentially number reaches and junctions along the selected flow path that has reaches connected end-to-end with each other.

If a reach(s) is already selected on the Map View before running the command, the same reach will be shown selected within the data table. The user can also select/unselect the desired reach by checking/unchecking the checkboxes corresponding to each reach that defines the flow path.

Alternatively, the user can click the [Pick] button to manually select the downstream most and upstream most reach on the Map View, and the software will then automatically determine all the junctions and reaches that connect with each other and form a river path.

Once the downstream and upstream reaches are selected, the dialog box will be redisplayed and the total number of selected reaches will be displayed in the Total selected read-only field.
Selecting Multiple (Interconnected) Reaches

Notes:

  • The user can select multiple reaches from the Map View before running the Renumber Interconnected Junctions command by holding the [Ctrl] key while selecting the desired reaches.
  • Only those reaches that contain irregular cross sections are listed.
  • Multiple reaches that reference the same irregular cross section geometry are not listed.

Manual Editing

This section contains a data table that lists the IDs of the selected reaches and junctions. The data table also lists the reach distance and total reach distance in miles and feet. The user can enter new reach and junction IDs in the table columns. Alternatively, the user can use the Reach Renumbering and Junction Renumbering panels to generate new reach and junction IDs as per the defined naming specifications.

Junction Renumbering

This panel allows the user to number the junctions based upon river chainage or incrementally.
Junction Renumbering

Junction Stationing

This section contains the following junction stationing options:

  • Junction ID prefix: This option allows a prefix to be added to the start of the junction ID.
  • Junction ID suffix: This option allows a suffix to be added to the end of the junction ID.
  • Junction ID preview: This entry provides a preview of the junction naming specifications defined above.
  • Numbering direction: This dropdown combo box defines the direction in which the junction IDs are increasing. The following options are available:
    1. Increasing Downstream
    2. Increasing Upstream (HEC-RAS style)

Use Reach Distance

The Use reach distance subsection is used to number the junctions by using the river chainage along the defined flow path. By default, this radio button option is selected.

The following options are provided in this subsection:

  • Downstream junction ID: This entry provides a junction ID that will be used as the downstream most reach station.
    Note that if the Increasing Downstream option is selected from the Numbering direction dropdown combo box, then the Downstream junction ID entry will change into Upstream junction ID. In addition, the numbering methodology will be altered to account for the selected direction.
  • Distance units: This dropdown combo box defines the unit of reach length. The available options are:
    1. Feet
    2. Miles
  • Decimal precision: This optional checkbox entry defines the decimal precision that will be used in determining the reach stations. By default, this checkbox is unchecked. If checked, then the user can enter a value ranging from 0 to 15.

Clicking the [Preview] button will cause the software to automatically fill in the junction IDs in the New Junction ID column of the Manual Editing data table.
Use Reach Distance

Use Auto Increment

The Use auto increment subsection is used to number the junction using a fixed increment. The user can select the Use auto increment radio button option to enable the content of the subsection.

The following options are provided in this subsection:

  • Junction ID digits: This option allows the user to set the number of digits to be used for junction ID. For example, using 3 digits causes the junction ID to be of the format 001, 002, etc.
  • Next available Junction ID: This entry defines the next element ID number to be used.
  • Junction ID increment: This entry defines the increment to use when numbering elements. The default value is 1.

Reach Renumbering

This optional panel allows the user to number reaches based upon river chainage or incrementally. By default, the checkbox on the Reach Renumbering panel is checked. If this panel is unchecked, then the content under this panel will be disabled (i.e., grayed out) and the reach renumbering cannot be performed.

Reach Stationing

This section contains the following reach stationing options:

  • Reach ID prefix: This option allows a prefix to be added to the start of the reach ID.
  • Reach ID suffix: This option allows a suffix to be added to the end of the reach ID.
  • Reach ID preview: This entry provides a preview of the reach naming specifications defined above.
  • Numbering direction: This dropdown combo box defines the direction in which the reach IDs are increasing. The following options are available:
    1. Increasing Downstream
    2. Increasing Upstream (HEC-RAS style)

Use Reach Distance

The Use reach distance subsection is used to number the reach by using the river chainage along the defined flow path. By default, this radio button option is selected when the Reach Numbering panel is checked.

The following options are provided in this subsection:

  • Downstream reach ID: This entry provides a reach ID that will be used as the downstream most reach station.
    Note that if the Increasing Downstream option is selected from the Numbering direction dropdown combo box, then the Downstream reach ID entry will change into Upstream reach ID. In addition, the numbering methodology will be altered to account for the selected direction.
  • Distance units: This dropdown combo box defines the unit of reach length. The available options are:
    • Feet
    • Miles
  • Decimal precision: This optional checkbox entry defines the decimal precision that will be used in determining the reach stations. By default, this checkbox is unchecked. If checked, then the user can enter a value ranging from 0 to 15.

Clicking the [Preview] button will cause the software to automatically fill in the reach IDs in the New Reach ID column of the Manual Editing data table.
Use Reach Distance

Use Auto Increment

The Use auto increment subsection is used to number the reach using a fixed increment. The user can select the Use auto increment radio button option to enable the content of this subsection.

The following options are provided in this subsection:

  • Reach ID digits: This option permits specification of a set number of digits to use for reach ID. For example, using 3 digits causes the reach ID to be of the format 001, 002, etc.
  • Next available Reach ID: This entry defines the next element ID number to be used.
  • Reach ID increment: This entry defines the increment to use when numbering elements. The default value is 1.

Once all the required data inputs have been defined, click the [Apply] button and the software will assign the user-defined changes along a defined flow path.
