Stormwater Controls Tab (Analysis Results Dialog Box)
Use the Stormwater Controls tab to review individual analysis of stormwater basins, such as ponds, in your drainage system.
- Use the Status filter at the top of the page to isolate objects with specific statuses as detailed below.
- Use the Zoom to Object
tool to locate the object and correct any drawing issues such as connections, location, object type, sizes, and elevation. - Use the Object Properties
dialog boxes to update any parameter issues for the object.
Name. Displays the name of the element.
Status. Reports if the flow in the pipe is OK, Flood Risk or Flooded, based on the maximum water elevation in the Junction.
OK. The maximum water elevation is below the Freeboard elevation (top of pond elevation minus freeboard depth).
Flood Risk. The maximum elevation is below the top of pond, but within the Freeboard.
Flood. The maximum water elevation is above the top of pond.
Exceedance Elevation. Reference parameter for the top of the pond or stormwater control when viewing status and flow depth.
Invert Elevation. Reference parameter for the bottom of the pond or stormwater control when reviewing other elevations and depths.
Max US Elevation. Displays the maximum upstream water elevation (above datum) reached in the pond for the selected or displayed rainfall event.
Max DS Elevation. Displays the maximum downstream upstream water elevation (above datum) reached in the pond for the selected or displayed rainfall event.
Max Avg. Elevation. Displays the maximum average water elevation (above datum) reached in the pond for the selected or displayed rainfall event.
Max Avg. Depth. Displays the maximum average water depth (above base elevation) reached in the pond for the selected or displayed rainfall event.
Max Inflow. Displays the maximum inflow (totaling all inlets) reaching the pond for the selected or displayed rainfall event. This does not include Bypassed inflow.
Max Resident Volume. Displays the maximum volume in the pond for the selected or displayed rainfall event including flooded volume.
Max Flooded Volume. Displays the maximum volume above the exceedance elevation or cover elevation in the pond for the selected or displayed rainfall event.
Max Outflow. Displays the maximum outflow (totaling all outlets) leaving the pond for the selected or displayed rainfall event.
Total Discharge Volume. Displays the total volume leaving the pond, through all outlets for the selected or displayed rainfall event.
Half Drain Down Time. Displays the 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. Displays the percentage of the total volume of the Stormwater Control available above the maximum water elevation measured to the exceedance elevation.
