How to Model Tracers for RDII, Runoff, GW and DWF in #SWMM5, #InfoSWMM and #PCSWMM

Image
A quick note:  A really nice feature of the way #SWMM5 models water quality is the easy ability to model tracers for the contribution of the major processes.  You can set up a concentration of 100 (for example) for DWF, RDII Flow, Runoff and Groundwater to find the percentage contribution of the process in link flow.  For example, if you model RDII using the RTK UH procedure the percentage of the RDII Water Quality Constituent is the flow from the upstream RDII nodes.  This technique can be used to show how important DWF, Separate Sewersheds and Combined Sewersheds to the WWTP flow or Outfall flow.
The following two images are from the Innovyze Products InfoSWMM and InfoSWMM SA


Figure 2.  RDII Concentration is the Percentage Contribution from RDII for the Linke Flow.

How  to approximate a Steady State Model in #SWMM5 and InfoSWMM using the Full Dynamic Wave Solution The five core components of making this work correctly are: Short Period of Time,Constant inflowEither use a hot start file or delay the results by time period in the Run MangerGraph the ResultsThe link and node components should be constant as shown in this image

World Class Software Documentation for SWMM5 from Lew Rossman and Wayne Huber (Hydrology)

I posted this on the SWMM Group on LinkedIn World Class Software Documentation for SWMM5 from Lew Rossman and Wayne Huber (Hydrology) I have noticed based on email questions and postings to the SWMM LIst Sever (a great resource hosted by CHI, Inc.) that many SWMM 5 users do not know about the really outstanding documentation on SWMM 5 posted on the EPA Website https://www.epa.gov/water-research/storm-water-management-model-swmm It consists of two now and in the near future three volumes on Hydrology, Water Quality, LID’s and SuDs and Hydraulics. The documentation is fantastically complete with detailed background on the theory, process parameters and completely worked out examples for all of the processes in SWMM5. It is truly an outstanding aid to modelers and modellers worldwide. It would benefit you to read them (if you have not already downloaded the PDF files). Thanks for reading this post

Innovyze Releases RDII Analyst Generation V14.5

Innovyze Releases RDII Analyst Generation V14.5,
Setting New Standard for Managing and Operating Sewer Systems

New Version Fully Supports Sewer Condition and Rehabilitation Priorities and Sewer Capacity Assessment
Broomfield, Colorado, USA, June 6, 2017 – Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the release of RDII Analyst (Rainfall-Derived Inflow and Infiltration) Generation V14.5 for InfoSWMM and InfoSWMM SA. The new version delivers both new and expanded functionalities for the quantification of RDII and help capacity analysis and the condition assessment of sewer systems. The release confirms Innovyze’s commitment to giving the world the most complete toolset for managing, operating and sustaining high-performing sewer systems.
Excessive wet weather flow from rainfall-derived manhole and pipe defect inflow and infiltration is a major source of sanitary and combined sewer overflows. Controlling t…

Extran Hydraulics Master from #Extran3 and #SWMM4 converted to #SWMM5

This is part of the #Inside_#SWMM5 series of blogs and is intended as a visual aid and code developer for the Storm Water Management Model Reference Manuals on https://www.epa.gov/water-research/storm-water-management-model-swmm  I always think images (and some words) are best at explaining the internal working of code.  I do encourage you to read the wonderfully written Storm Water Management Model Reference Manuals.
The following is a combined #Extran3 and #SWMM4 reference manual models in #SWMM5 format.  Examples 1 through 6 were combined together in one #SWMM5 model.

How Do the TimeOpen and TimeClose Controls Work in #SWMM 5.1.012

Image
This is part of the #Inside_#SWMM5 series of blogs and is intended as a visual aid and code developer for the Storm Water Management Model Reference Manuals on https://www.epa.gov/water-research/storm-water-management-model-swmm  I always think images (and some words) are best at explaining the internal working of code.  I do encourage you to read the wonderfully written Storm Water Management Model Reference Manuals.
The controls we are examining are the TIMEOPEN and TIMECLOSED commands in #SWMM5.  These commands are defined in the SWMM5 help file as TIMEOPEN is the duration a link has been in an OPEN or ON state or have its SETTING be greater than zero; TIMECLOSED is the duration it has remained in a CLOSED or OFF state or have its SETTING be zero.
Here is an example rule,
RULE COUNT1 IF SIMULATION TIME > 0.0 THEN PUMP PUMP1@82309e-15009e SETTING = 1.0 PRIORITY 1
RULE COUNT2 IF PUMP PUMP1@82309e-15009e TIMEOPEN >= 2 THEN PUMP PUMP1@82309e-15009e SETTING = 0.0 PRIORITY 5
