  • Thank you Robert.
    Is it possible to get a reply on a question not directly related to SWMM?
    I apologize if I broke the forum rules with it.

  • it's easy... all you need to do is write like you talk and think... slow your thoughts down so you can capture it on paper!

  • Okay.  Thanks for your help Bob.  I'll adjust my width and see how that affects the graph.

  • Hi Bob, Could you tell me why I have such a sharp corner at the point where the falling limb starts on this hydrograph?  I have set up a 'dummy' model with one subcatchment and one conduit just to see the effects of different parameters.  For this setup, however, I would expect that the top right corner of the hydrograph would match exactly the top left corner.  I have set no infiltration.  Thanks!  Flow%20Graph%20showing%20discontinuity.PNG

  • Thanks.... :)

  • Thanks for your reply Bob.  I have now just encountered a - " is not a valid integer - error message.  All my subcatchments no longer show in the model!  Do you have any suggestions as to what this error is and how I can retrieve my work?  Thanks.

  • Thank you Bob

  • Hi Bob,

    Question for you regarding overland flow travel time from subcatchments to nodes.  Does EPA SWMM 5 measure the overland distance from the farthest point of the subcatchment to the centroid of the area?  If so, how can I get an accurate flow distance if my desired subcatchment outlet node is on the edge of the subcatchment, not near the centroid?  Thanks in advance.
