How to:

Model Gradually Varied Flow in Bentley FlowMaster and hydraulic jumps

Steps to Accomplish

Programs like StormCAD and SewerCAD use Gradually Varied Flow as part of the analysis process. Bentley FlowMaster also has the ability to model gradually varied flow for an individual conduit.

The steps to use this are similar to the Uniform Flow. In fact, you would still enter data for Uniform Flow.

 

In the screenshot above, you see data input for Uniform Flow in a circular pipe while solving for "Discharge". The results for Discharge and on the right side of the worksheet are for such a case. If you want to see gradually varied flow results, click the Gradually Varied Flow tab and enter the appropriate data. You will then see results related to gradually varied flow.

Note that the Profile Description in this case is "Composite S1 -> S2". This signifies that a hydraulic has occurred. If you click the GVF Profile button, you can see a graphical depiction of this jump.
