Inspect visually and check data for the hydraulic and energy grade-lines for a selected pipe run. Identify surcharged pipes and flooded manholes. Adjust AEP setting to model performance under different storm level conditions.
- Run Size Drainage Network if you have not run it since making changes to the drainage network.
Click
- Click
, Inspect Performance.
- Optionally, before selecting the first pipe connector, adjust the AEP setting, as needed. Default setting = 1/10.
- Follow tool tip instructions at bottom of canvas.
- Select a first pipe connector. (Selection highlights yellow.)
To change a selection of a pipe connectors before analysis starts, click the connector again to deselect it, then select a different one.)
- Select a second connector from the eligible connectors. (Highlighted purple.)
- The pipe run to be analyzed is now marked between two yellow connectors.
- Click Enter to start the analysis.
Note: You cannot select underground drainage structures from (through) the road or terrain surface. Navigate beneath the surface to select the structures.
Inspect Performance returns:
- Labels a surcharged inlet or a flooded manhole.
- Visual analysis of the hydraulic and energy grade-lines, measured against the obvert of the pipe. To check the data, move the cursor over the vertical bar along the hatched bounding box.
Blue bar: the depth of water in the pipe (not the flow); that is, the hydraulic gradeline.
Green line: the obvert, or inside, of the pipe.
Yellow line: the energy gradeline.
