How do I set a minimum shear stress to ensure the tractive forces are large enough to scour the pipes?
Note: This only applies in SewerGEMS if you are using the GVF Convex Solver
You can set this in the calculation options in the location shown below
You can also specify local tractive stress on a per-pipe basis:
Then, after computing the model (GVF Convex Solver), you can see the calculated tractive stress and whether or not it met the target. These results are found in the properties of the conduit under the "Results (Tractive Stress)" section or in a Flextable.
You can also color code by "tractive stress target exceeded" or "tractive stress target ever exceeded" to visualize:
