Stormwater Management Model (SWMM) Information for watershed water quality, hydrology and hydraulics modelers (Note this Blog is not associated with the EPA). You will find Blog Posts and Twitter Embeds on the Subjects of SWMM5, InfoSWMM, InfoSewer, SWMMLive, InfoSWMM SUSTAIN, SWMM4 and SWMM in general.
Note: Area Scaling Factor in #INFOSWMM and #H20MAPSWMM is needed if you want to update the DB from the Map after drawing a Subcatchment. The Auto Area Calculation Flag has to be turned on for this to work. Why did I write this blog? The USA conversion is really hard to remember!

I first started using twitter in 2008 thanks to our daughter @boonsri and my love of timelines. My goal is to reach 100,000 tweets if I last long enough and Twitter lasts enough years. I would have over 100,000 tweets now if I had started in 1980 and tweets were possible in the 80's
Questions after a
Main Break | Webinar on Smart Asset Planning Water main breaks
are prevalent in all cities. As engineers and planners, we do
everything we can to avoid them and mitigate damages when they occur.
Communicating those plans and educating the general public is another
story. Having a clearly defined and defensible rehabilitation plan
is the foundation for better education of stakeholders. They want
Why did this water
main fail? What was the likelihood of this water main to fail?
Was there an assessment (financial, environment, and social) on this
pipe failing? Was this pipeline planned to be repaired/upgraded in the
Take a look at a

made this example to show how oscillations occur for legitimate reasons and
the best ways to test the oscillations in InfoSWMM and SWMM 5: Oscillations
due to downstream obstructions, downstream mixed solutions and downstream
boundary conditions: In
this case the oscillation in some links is due to the culvert comparison which
limits the flow based on the inlet equation. You can see the flow changes
if you turn on show control actions in the run manager. The program will
then show the changes in the HTML report file. The flow oscillation is
due to the water being stored at the upstream node of the culvert followed by
the excess flow going into the culvert. How
to check the validity of the solution: Use a Map Display of the Link
Result Variable Link Volume. If you do a map display of the link total
volume you will see that the total volume passing through each link is in
balance. You were using a 30 minute report time step, you can see and
understand the oscillations better if…
