How InfoSWMM uses Calibration or monitored data during a Simulation

How InfoSWMM uses Calibration or monitored data during a Simulation

The calibration data is used in the Calibrator Addon (which uses a Genetic Algorithm  to calibrate RDII, Subcatchment, Infiltration, Groundwater, Pipe, Node or Pump input data to calibration data) by running a model many times to optimize the fit (Figure A).  The fit between measured and simulated results can be viewed in the Output Report Manager with comparison statistics on the graph (Figure B).  The monitored data is linked to your model using the Calibration Tool (Figures C, D and E) and the GA Calibration process is controlled by many best fit options (Figure F).

How to Define Green Ampt Infiltration in ICM

Here are the steps to make a Subcatchment with Green Ampt Infiltration in ICM:

1.       You use the Subcatchment, Land Use and Runoff Surface Tabs in the Subcatchment Grid (Bullet 1)
2.      The Subcatchment Tab has three Runoff Areas for Impervious with Depression Storage or Initial Loss, Impervious with no Initial Loss and Pervious Area (Bullet 2)
3.      The Runoff Surface percentages on the Subcatchment are connected to the Land Use Tab by the Land Use ID, in this example we are using Runoff Surfaces 22, 23 and 24 (Bullet 3)
4.      The Runoff Tab defines the Runoff Surfaces defined in the Subcatchment Tab and Land Use Tab (Bullet 4)
5.      You can define the Routing Model per Runoff Surface or SWMM in this case (Bullet 5)
6.      The type of Runoff Surface and Surface Type for each Runoff Surface or GreenAmpt for Runoff Surface ID of 24 (Bullet 6)
7.      The Depression Storage or Initial Loss Value for each Runoff Surface in the Runoff Surface Tab (Bullet 7)
8.     The Green Ampt Infiltration Parameters are defined to the right in the Runoff Surfaces Tab (Bullet 8)
a.      Suction in inches or millimeters
b.      Saturated Hydraulic Conductivity in inches/hour or mm/hour
c.       Deficit as a fraction

Hazen Williams and Force Mains in SWMM 5

A few tips for using Hazen Williams and Force Mains in SWMM 5.   A key fact is to remember ONLY one flow in the middle of the link is computed in SWMM 5 so you may have to add Break nodes, use a smaller time step and use a flap gate depending on how often your pumps turn on.  If you do not have numerical problems with the time step you should get exactly the same head loss as you do in steady state Hazen Williams calculators when you use InfoSWMM, H2OMap SWMM and SWMM 5.

Figure 1.  Larger Tip Image 
Figure 2.  SWMM 5 compares well to the Hazen Williams Head loss calculators



Ganesh ji and Modelling

I have always thought that Ganesh ji is an ideal God or Symbol for modellers or even modelers.    Here are a few of his characteristics including a large stomach, which you can combat by exercise - I love walking but find what works best for you.

Knowing How to Change Your Mind: A Three Minute Guide to Bayesian Reasoning       

NEW LESSON

with Julia Galef

Since you cannot really be 100 percent certain of a theory, a better way to put it to yourself is to say "I think this is very likely to be true."     http://bigthink.com/big-think-mentor/knowing-how-to-change-your-mind-a-three-minute-guide-to-bayesian-reasoning

My History with Various Versions of SWMM: SWMM3, SWMM4, SWMM5, XP-SWMM and InfoSWMM

Subject:   My History with Various Versions of SWMM: SWMM3, SWMM4, SWMM5, XP-SWMM and InfoSWMM

I first learned about SWMM in a brochure from the University of Florida when I was just a 17 year old senior in High School.  Water resources and the description of SWMM seemed to be worthy career goals at the time and I have been extremely lucky to have the opportunity to work and develop many SWMM related products in my working life.   I am especially proud that SWMM 3, SWMM 4 and SWMM 5 are both public domain and open source software.  You can open up and look at the code and add features and internal tests on your own.   You can customize the input and output of SWMM 5 if you want to but most importantly you have direct access to the source code so you can verify the computational algorithms.


InfoSWMM is an Arc GIS extension that works in Arc Map but we at Innovyze are proud that we have superb import and export features to SWMM 5 from Arc Map and use the SWMM 5 engine as our engine solution.   You can look at the internal workings of the InfoSWMM engine by downloading the current SWMM 5 C code from the EPA website http://www.epa.gov/nrmrl/wswrd/wq/models/swmm/   InfoSWMM also has all of the Arc GIS programming tools, Python programming,  editing and drawing features and Table of Contents attribute features to make a better model but that model will still use the open source SWMM 5 engine inside of InfoSWMM.    When you use InfoSWMM you are using the SWMM 5 engine  but with many extra input and output features to help prepare the data for the current SWMM 5 engine and analyze the SWMM 5 engine output  in maps, tables and graphs.


The following was edited to reflect the passage of time:
PS in 2013/2016. I am now at my 45th anniversary of 1st hearing about SWMM, my 41th anniversary of seeing Wayne Huber or Jim Heaney mention SWMM in an Introduction to Environmental Engineering Course at UF, my 39th anniversary of 1st seeing the SWMM 2 punch cards for a mainframe computer, my 37th aniversary of meeting Bill James of UG and the Future CHI and Larry Roesner of CDM and now with CSU, my 36rd anniversary of being a coauthor and coprogrammer of SWMM 3, my 28th anniversary of being a coauthor of SWMM4, my 24st anniversary of being a XP-SWMM developer, my 18th year anniversery of being a Visual SWMM developer at CAiCE, 18 years since I first heard of Paul Boulos and MWH Soft, 17 years since I first meet Lew Rossman, 16 years since I first started working on SWMM 5 while at CDM with all of my great CDM colleagues (Jim Smullen, Ted Burgess, Carl Chan, Khalid Khan etc) and Lew Rossman and Trent Schade at the EPA and now 9+ years at Innovyze with our worldwide network and dedicated engineers and developers.   I have also learned very much from our really good customers and their important/interesting models.


Odd, I thought I had a lot of experience before I joined Innovyze in 2008 but dealing with the synergy of support, development, sales and training for multiple software products around the world brings it with another level of understanding and insight into modeling and model development.  Thanks very much to all my Innovyze customers, Innovyze Management, Innovyze CSM's, Innovyze Developers, Innovyze Support Engineer and Innovyze in general. My special thanks to Paul Boulos, Roger Ro, Fayu Lai and Chun-Hou Orr for their support, brilliance and creativity.  I could also thank hundreds or customers but Stewart and MJ stand out in my mind as being the best and most creative and I wish them both well in their future.  Keith Hodsden and Paul Hsiung are also standout CSM's at Innovyze and I owe them a lot as does the engineering community in general.



I would be amiss if I did not mention my wife and three children/offspring who have had to live with the world SWMM for her whole married life or literally their whole lives in the case of my children.  I could not have done it without my wife's organizational skills, hard work and patience.  We have learned from our children their whole lives - they are also hard working, brilliant engineers and writers/developers who have always impressed me as being smarter their parents, which made them easy to raise.  Here is a short video about how they helped me with SWMM: A Short Film: What Is The Meaning of Life? http://www.youtube.com/watch?v=lRQAIRBDVxw&feature=youtu.be … [inspired by @RDickinson & shot with @googleglass & edited w/ @givit] Thanks @boonsri

Edward Burtynsky's Water

Edward Burtynsky's Water  

Burtynsky Water 01
Burtynsky Water 02
Photographer Edward Burtynsky's latest project is called Water.
While trying to accommodate the growing needs of an expanding, and very thirsty civilization, we are reshaping the Earth in colossal ways. In this new and powerful role over the planet, we are also capable of engineering our own demise. We have to learn to think more long-term about the consequences of what we are doing, while we are doing it. My hope is that these pictures will stimulate a process of thinking about something essential to our survival; something we often take for granted -- until it's gone

How the Steady State option works in H2OMap SWMM and InfoSWMM

How the Steady State option works in H2OMap SWMM:
1.       Use Keep, a Time Step lengthening of 10 seconds, a time step of 60 seconds and iterations as shown in Bullet 1
2.      Use the Steady State Option of Skip Steady State Period when the total inflow between time step is less than 0.05 cfs or the equivalent in lps or cms units
3.      A time step of 10 seconds will be used during Wet Weather, a time step of 60 seconds will be used during the transition between dry and wet weather or Bullet 3
4.      You should be able to speed up your by a factor of 10 to 2o to 1 depending on the frequency of rainfall  or Bullet 4
5.     This was 10 year simulation using the dynamic wave option of SWMM 5

The Effect of the Wrong Raingage Interval in H2OMap SWMM and InfoSWMM

Here is an example showing the Runoff, Rainfall and Infiltration losses when you use the wrong interval based on the hyetograph time series.
1.       Figure 1 shows the Rainfall, Runoff and Infiltration for a time interval of 5 minutes which matches the hyetograph interval, the raingage has units of mm and is the total volume over the interval
a.      The volume of rainfall is 20.03 mm as it the total rainfall over the interval
b.      The rainfall, runoff and infiltration graphs are smooth
2.      Figure 2 shows the Rainfall, Runoff and Infiltration for a time interval of 1 minutes which does NOT match the hyetograph interval, the raingage has units of mm and is the total volume over the interval
a.      The volume of rainfall is 20.03 mm as it the total rainfall over the interval
b.      The rainfall, runoff and infiltration graphs are not smooth as there is a gap of no rainfall between minute 1 and 5 for all of the hyetograph time intervals
c.       The peak rainfall is higher as the rainfall is over 1 minute instead of 5 minutes
d.      The peak runoff and infiltration rates are also higher but this difference depends on the roughness, depression storage and infiltration parameters of the catchment
e.      The slower the runoff the more Figure 1 and Figure 2 runoff will look alike even though the rainfall is the spiky versus smooth (Figure 3).



Figure 1.  The Rainfall, Runoff and Infiltration loss for a gage interval of 5 minutes which matches the Time Series Interval

Figure 2.  The Rainfall, Runoff and Infiltration loss for a gage interval of 1 minutes which does not  match the Time Series Interval


Figure 3.  The Rainfall, Runoff and Infiltration loss for a gage interval of 1 minutes which does not  match the Time Series Interval, the Subcatchments Width is smaller than was used in Figure 1 and Figure 2
