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!

BMDOkay. 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!

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.
