Inlet summary results not available for non-street conduits

Open dapaez270 opened this issue 2 years ago • 2 comments

SWMM5.2 allows to assign custom inlets to any kind of conduit (i.e., any type of cross-section including non-streets) and drop inlets to open rectangular and open trapezoidal conduits, besides the regular inlets for the street conduits. However, in the Summary Results tables, the Inlet Location, Peak Flow Capture, Average Capture, Bypass Frequency, and Backflow Frequency results are only reported for street conduits.

I think these results should be reported for any conduit with an inlet assigned, independently of their cross-section.

will it work with any cross section type? maybe it needs a street shape to compute the capture values.

SWMM will compute the captured flows for all inlets that are consistent with their cross section. In this example there is a rectangular open channel with a drop grate inlet that produces a lateral flow to its capture node:

One could compute manually those summary statistics based on these plotted results, but they would be based on the reporting time step and not the computing time step, making it inconsistent with the results for Street conduits.
