The Stormwater Controls Summary Results shows a summary of how each Stormwater Control 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 Stormwater Control 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 Path.

When the All Storms radio button is selected, the summary shows the maximum flow rates in and out of the Stormwater Control 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.

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.

Results

Max Level - The maximum water level (above datum) reached in the item for the selected or displayed rainfall event.

Max Depth - The maximum water depth (above base level) reached in the item for the selected or displayed rainfall event.

Max Inflow - The maximum inflow (totaling all inlets) reaching the item for the selected or displayed rainfall event.

Max Resident Volume - The maximum volume in the item for the selected or displayed rainfall event including flooded volume.

Max Flooded Volume - The maximum volume above the exceedence level or cover level in the item for the selected or displayed rainfall event.

Total Lost Volume - The total volume lost to infiltration, interception and evapotranspiration.

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.

Half Drain Down Time - A measure of the time it takes for a Stormwater Control to drain down from its maximum depth to half its maximum depth at the average outflow rate as measured at the maximum depth and half maximum depths. 

Percentage Available - The percentage of the total volume of the Stormwater Control available above the maximum water level measured to the exceedance level.

Status - Based on the level in the Stormwater Control, the following status will be shown:

  • OK - The level is below the Exceedence Level minus the Freeboard.
  • Flood Risk - The level is below the Exceedence Level but is within the Freeboard.
  • Flood - The level is above the Exceedence Level.

An asterisk * may be shown next to the status if the outflow is blocked by the DS level. This means the DS water level has met or exceeded the level in the stormwater control and therefore water has been prevented from moving forward. When the DS level drops, flow will continue again.
