Junctions - Item Results shows a summary of how the selected Junction performed for the current storm/event as highlighted on the Storm Selector.


Provides 4 graphs showing different aspects of the result, each of which can be turned on and off as required. For more information, see the Graph Tools  and Results Graphs pages.

 Flows - shows the Rainfall, Total Approach Flow (entering the inlets), per Inlet (Continuation and Bypass), Total Inflow (After inlet restriction) and Outflows (Total and per Outlet) into and from the Junction against time.

 Volumes - Shows the Volume of water in the Junction against time. Note that this option is not available for Simple Junctions.

 Depths - Shows the water Depth in the Junction against time. The Exceedence Depth (Cover Level - Invert Level) is shown for reference to identify when flooding occurs.

 Pollution - Shows the Pollutant concentrations in the Junctions against time. Note that this option is not available for Simple Junctions.


Shows the minute by minute data from the analysis of the system for Inflows, Outflows, Depths, Volumes and Pollutants. The toggles can turn on and off columns as required.

 Component Inflow - when turned on, the Inflow per Inlet and Total Approach Flow are shown in addition to the Total Inflow.

 Component Outflow - when turned on, the Outflow per Outlet is shown in addition to the Total Outflow.

 Pollutant Concentrations - when turned on, the Pollutant Concentrations are shown. Note that this option is not available for Simple Junctions.

The information is 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.

Output Interval

The output interval comes from the value selected in the  Analysis Criteria. The results are averaged over the output interval period, for example if the Output Interval is 5 minutes and the Analysis Interval is 1 minute, the results calculated for the 1 - 5 minutes intervals are averaged to produce the 5 minutes result.


Provides a break down of the Pollutant loads entering and leaving the system as well as details of the Concentrations.
