Subject:  Infiltration Data in SWMM 5 Infiltration Data in SWMM 5 by  dickinsonre Subject:  Infiltration Data  in SWMM 5 If you are using Non linear Reservoir Modeling in SWMM 5 there are 1.     Five parameters for Horton Infiltration, 2.     Three parameters for Green-Ampt and 3.     Two parameters for CN infiltration, one parameter (conductivity) has been deprecated by the EPA in SWMM 5.   The Drying Time is used to regenerate the Infiltration Rate for continuous simulation.  Only two parameters are now used for CN infiltration:  The CN value itself and the drying time.     via Blogger  http://www.swmm5.net/2013/08/ infiltration-data-in-swmm-5. html

A feedback loop involves four distinct stages

Image
A feedback loop   involves four distinct stages. First comes the data: A behavior must be measured, captured, and stored. This is the evidence stage. Second, the information must be relayed to the individual, not in the raw-data form in which it was captured but in a context that makes it emotionally resonant. This is the relevance stage. But even compelling information is useless if we don’t know what to make of it, so we need a third stage: consequence. The information must illuminate one or more paths ahead. And finally, the fourth stage: action. There must be a clear moment when the individual can recalibrate a behavior, make a choice, and act. Then that action is measured, and the feedback loop can run once more, every action stimulating new behaviors that inch us closer to our goals, From Wired Magazine http://www.wired.com/magazine/2011/06/ff_feedbackloop/all/1

SWMM 5 Slope Rules are Critical to Understand for Short Pipes

Subject:   SWMM 5 Slope Rules are Critical to Understand for Short Pipes If you have a short pipe and an significant offset depth for the pipe at either the upstream or downstream end of the pipe then the difference between the arithmetic method of calculating the slope and the SWMM 5 method can be noticeably different.

How to Make a Small Model out of a Large Model in H2OMAP Sewer

Subject:  How to Make a Small Model out of a Large Model in H2OMAP Sewer How to Make a Small Model out of a Large Model in H2OMAP Sewer and InfoSewer by  dickinsonre Subject:   How to Make a Small Model out of a Large Model in H2OMAP Sewer The process is easy if you use Domain and Facilities.   Step 1.  Use the Trace Upstream Network Command in Utilities to find the upstream network from your node of interest.  The upstream network is saved to a Domain. Step 2.  Use the Facility Manager to 1 st  deactivate the whole network and then 2 nd  to add the Domain to your Facility or the nodes and links that you will simulate You now have a smaller network to examine in Detail.  You may have to make a temporary Outfall node to run the model if there are no Outfalls in the model. via Blogger  http://www.swmm5.net/2013/08/ how-to-make...
