Junctions Summary
- Abraham Toribio II
The Junctions Summary Results shows a summary of how each Junctions in the current phase performed.
Filtering the Results
When the All Items radio button is selected, the summary shows the maximum flow rates entering and leaving together with details of the volumes for each of the Junctions in the Phase for the current storm/event as highlighted on the Storm Selector on the Status Bar. The Select Filter drop down filters the results to show All Items or a selected Flow Paths.
When the All Storms radio button is selected, the summary shows the maximum flow rates in and out of the Junctions selected in the Select Item drop down, together with details of the volumes for each of the storms run. This is of most interest when Rainfall with multiple storms is selected on the Analysis Criteria.
Critical Storm
When pressed, the Critical Storm toggle button will display the critical storm in the following ways:
- When the All Items radio button is selected, the critical storm and its results for each Junction are displayed, rather than the selected storm.
- When the All Storms radio button is selected, the row containing the critical storm for the currently selected Junction is highlighted in orange. If two or more storms are critical only the first one will be highlighted.
The critical storm for a Junction is defined to be that storm that has the largest Max Depth result.
Spreadsheet Preferences
Fields can be turned on or off using the Spreadsheet Preferences form that is accessed from the toolbar at the top of the form. The full set of columns available are shown and can be turned on or off using the check boxes. These settings will be remembered between sessions.
Simulation Health
If the results of the analysis are showing issues for the current storm, or one of the storms if showing critical/all storms, a message will be shown at the top of the form. More information can be found in the Simulation Health section.
Results
Cover Level - The cover level of the Manhole is shown for reference.
Invert Level - The invert level of the Junction is shown for reference. Note: if abstract connections (No Delay, Lagged Flow) are connected to a simple junction then this will be left blank).
Max Level - The maximum water level (above datum) reached in the item for the selected or displayed rainfall event. Note: if abstract connections (No Delay, Lagged Flow) are connected to a simple junction then this will be left blank).
Max Depth - The maximum water depth (above invert level) reached in the item for the selected or displayed rainfall event. Note: if abstract connections (No Delay, Lagged Flow) are connected to a simple junction then this will be left blank).
Max Inflow - The maximum inflow (totaling all inlets) reaching the item for the selected or displayed rainfall event. This does not include Bypassed inflow.
Max Resident Volume - The maximum volume in the item for the selected or displayed rainfall event including flooded volume. Note: if abstract connections (No Delay, Lagged Flow) are connected to a simple junction then this will be left blank).
Max Flooded Volume - The maximum volume above the exceedence level or cover level in the item for the selected or displayed rainfall event. Note: only Manholes can flood.
Max Outflow - The maximum outflow (totaling all outlets) leaving the item for the selected or displayed rainfall event.
Total Discharge Volume - The total volume leaving the item, through all outlets for the selected or displayed rainfall event.
All numeric columns are shown to a default number of decimal places based on the unit. If you want to see more or less decimal places, you can select Increment Decimal or Decrement Decimal from the right click menu. This setting will not be saved between sessions.
Status - Based on the level in the Junction, the following status will be shown:
- OK - The maximum water level is below the outgoing Pipe Soffit or for other connection types the level is below the Cover Level.
- Surcharged - The maximum water level is below the Cover Level but is above the outgoing Pipe Soffit.
- Flood Risk - The maximum level is above the outgoing Pipe Soffit but is below the Cover Level by the Flood Risk Margin depth.
- Flood - The maximum water level is above the Cover Level.
