You can carry on from the previous Chapter or switch to the Sizing of Treatment Phase by selecting from the drop-down list on the left Tree View panel if you have not already done so. After switching to this Phase, Run the simulation by selecting Go under the Analysis tab.
The Stormwater Controls Summary result table appears automatically after an Analysis has been run. These results indicate at a glance how oversized or how close to overtopping a SWC may be. The Stormwater Controls Summary result table can also be selected on the Results ribbon.
The different storm events simulated can be selected by using the Storm Selection list at the bottom of the screen or on the Results ribbon. Note the Percentage Available volume in the SWCs and if there are any Flood Risk or Flooded status for each Storm.
Viewing a long section Profile of the entire Treatment Train is often the easiest way to check the volume performance on a site. The Profiles > Train can be selected under the Viewribbon. The Profile animation playback is located at the bottom of the Profile view.
All objects shown within the Profile view can be edited by double-clicking an individual item. The image below shows editing the Swale SWC.
A quantified comparison between the Existing and Developed Phases can be made using the Phases Report option under the Results ribbon.
Select the Update Preview option in the lower left of the Phases Report dialog to provide both tabular and graphical comparisons. By scrolling down through the three storm events, you will find whether or not the Developed conditions design meets or exceeds the Existing site discharge. Depending on how the initial Treatment Train was laid out, small differences between the comparison shown below may be observed.
As shown with the Phases Report comparison, the Developed phase is largely over discharging flow compared to the Existing phase. Facility sizing and further outlet configuration is required to adequately reduce offsite impacts.
