Oscillations in SWMM 5 and InfoSWMM

I 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 you use a 1 minute report step.   In the culverts even though the flow in the culvert oscillates the mean flow is being passed downstream – that is why the downstream flows are constant.  I am trying a different way of modeling the steady state flow = this model does not have a continuity error but since the inflow to the culvert is oscillating between two solutions you are getting an uncertain flow.

A Top Ten List of Advantages of InfoSWMM over SWMM 5 (IMO)

Introduction:  I have been working on the various versions of SWMM since 1980 when I was a co-author and co-developer of SWMM3, a co-author and co-developer of SWMM4 in 1988 and a co-developer of SWMM 5 from 2002/2006.   I have worked at Innovyze as a Product Sector Leader since 2008 and have grown to love the power and ability of InfoSWMM and all Innovyze software such as InfoWater, ICM, H2OMap SWMM and InfoSewer.  This blog post explains based on my experience why  InfoSWMM makes you a better modeler or modeller for the SWMM 5 engine rather than just directly using the SWMM 5 engine and GUI available from the USEPA.  I am still an almost daily user of SWMM 5 so I have a constant comparison between the ability of the InfoSWMM Modeling Platform over the SWMM 5 GUI. 

First a  brief Introduction to InfoSWMM or a reminder of the history of InfoSWMM: InfoSWMM for ArcGIS (Esri, Redlands, CA). InfoSWMM  enables engineers to work more efficiently and reliably with very large and complex network models, thanks to improvements in such areas as built-in 64-bit simulation, enhanced water quality modeling, and batch run scenario management using many of the Arc Map tools developed for InfoWater and InfoSewer.. All operations of a typical sewer system — from analysis and design to management functions such as water quality assessment, pollution prediction, sediment transport and deposition, urban flooding, real-time control, and record keeping — are addressed in a single, fully integrated geoengineering environment. The program’s powerful hydraulic and water quality computational engine is based on the current SWMM 5 version, which is endorsed by the USEPA and certified by FEMA.  You can also get almost 24/7 support for InfoSWMM from Innovyze by emailing us at support@innovyze.com 

My Top Ten Reasons for preferring InfoSWMM over SWMM 5 based on my experience

These are the top ten expanded reasons I have found over the last ten years for using InfoSWMM over the SWMM 5 GUI. I will start at the beginning that all of these fantastic features in InfoSWMM are due to our wonderful programmers in Monrovia (CA), Broomfield, Denver(CO) and Wallingford (UK).
