Arc Map If Statements for Showing Flooding in InfoSWMM

You can use a combination of the Map Display in InfoSWMM and the Arc Map Label Properties to show the Maximum Ponded Volume at a node during amInfoSWMM simulation. 

The label function in VBSCRIPT to show just non zero flooded volumes(Figure 1) is:

Function FindLabel ( [PONDED_VOL] )
If [PONDED_VOL] > 0 THEN
  FindLabel = "" & FormatNumber([PONDED_VOL],2) & ""
END IF
End Function

and the values of Flooded Time,  Maximum Flooded Rate and Maximum Ponded Volume can be found in the Junction Attribute Table(Figure 2)  but not the Junction Summary Table of the InfoSWMM output report manager tables. 

A VBSCRIPT function to show both ponded volume and flooded rate (Figure 3) is:

Function FindLabel ( [PONDED_VOL], [FLOOD_RATE]  )
If [PONDED_VOL] > 0 THEN
  FindLabel = "" & FormatNumber([PONDED_VOL],2) & " / "   & FormatNumber([FLOOD_RATE],1)
END IF
End Function



Figure 1.  InfoSWMM Map Display of Ponded Volume which is the integral of node flooding over the flooded time.

Figure 2.   If you use the Map Display feature in InfoSWMM then the total flooded time, flood rate and maximum ponded volume will be shown in the Junction Attribute Table.

Subject:  Advanced SWMM 5 import into InfoSWMM and H2OMAP SWMM
The current version of InfoSWMM and H2OMAP SWMM not only imports the latest SWMM 5 version but it has built in flexibility that allows the user to import selected data sections, model data sections or auxiliary file information such as calibration data files.  This allows you the choice of importing non specific network data that can used in the model of any city, county, shire, town or watershed.  For example,  you can import only these sections without affecting the geometry of your network:
1.      Calibration File Information,
2.      RTC Rules
3.      Aquifers
4.      Snowpacks
5.      Buildup for Water Quality,
6.      Washoff for Water Quality,
7.      Evaporation,
8.      Time Series,
9.       DWF,
10.        Patterns,
11.        RDII
12.        Loadings,
13.        Curves,
14.        LID Controls,
15.        LID Usage,
16.        Pollutants,
17.        Land Uses
Possible uses of this feature would be to have a city wide or company wide library of LID controls, RTC Rules or RDII values.

Subject:   InfoSewer to InfoSWMM Import Tips
The direct import of InfoSewer to InfoSWMM (Figure 1) is both direct and robust but you need to be aware of Run Manager changes to optimize the InfoSWMMmodel:
1.       Make sure that the Flow Units in InfoSWMM Run Manager match the default flow units in InfoSewer so that the DWF values are comparable,
2.      Make sure that the Output Flow Units in InfoSWMM match the Output Flow Units in InfoSewer so direct comparisons are easier,
3.      Add a Pump On and Pump Off depth to the Pumps in  InfoSWMM so that the pumps work better in a fully dynamic solution,
4.      The Fixed Pump Curves of InfoSewer should be checked in the Pump Curve section of InfoSWMM to make sure they are comparable,
5.      The InfoSWMM conduit step lengthening option should be used to speed up the model if you have short links in InfoSewer,
6.      You can check the overall balance in the two modeling platforms by comparing the System Load Graph in InfoSewer to the Total Inflow Graph inInfoSWMM.

How to use the Flow Splitter in InfoSewer for Dendritic Networks

by dickinsonre
Subject:  How to use the Flow Splitter in InfoSewer for Dendritic Networks

InfoSewer, which is an extension in Arc Map, does need to have slit split defined where gravity mains merge together to determine the amount of flow in each of the downstream conduits (Figure 1).   The options for the flow splitterin each of the downstream links are:
1.       Automatic Allocation
2.       Fixed Flow Percentage
3.       Variable Flow Percentage and
4.       Inflow-Outflow Curve 
At an outfall where the invert of the outfall pipe is raised compared to the inverts of the incoming and outgoing pipes a flow split of Variable Flow Percentage or Inflow/Outflow curve may work better (Figure 2).

You Don't Work as Hard as You Think You Do

You Don't Work as Hard as You Think You Do

| Fri Oct. 19, 2012 8:14 AM PDT
Via Matt Yglesias, here's an interesting BLS study from David Yanofsky about how many hours people say they work vs. how many hours they actually work. This is actually sort of a pet topic of mine. My experience is solely with white-collar offices, but for years I noticed that my colleagues routinely overestimated how many hours they worked. As it happened, I frequently worked a little late and a little on weekends, so I had a good sense of just how many people were in the building after 6 pm or on Saturdays. Answer: virtually no one. You could fire a cannon through the place and not risk hitting anyone. And yet, people routinely thought they worked something like 50 hours a week.
But guess what? 50 hours a week is actually a lot. It means working until 7 pm every night. Or it means working until 6 pm every night and then working a solid chunk of hours on Saturday. And there just weren't many people who did that. (Nor was much work being done at home. You'll just have to trust me on that.) The numbers are even worse for 60 hours a week. You'd have to work 10-hour days routinely and a good chunk of hours on both weekend days. There are people who do this, but honestly, not all that many.
Anyway, the chart below demonstrates this graphically. It shows the gap between hours reported and hours actually worked:
As you can see, people who report working 50 hours a week typically overestimate by about 5 hours. My take on this has always been simple. If you stay late a couple of days a week, itfeels like a strain. You feel like you've really put in the hours. And since, in the modern work environment, 50 hours sounds only moderately hardworking (60 hours is the lower bound for real workaholics), that's what you convince yourself you worked that week. But the truth is that two or three late nights actually adds up to maybe 45 hours or so.
At the high end it gets even worse: 75 hours is 10-11 hours every day, or 12-13 hours six days a week. Not many people really do that. But if you work 60 hours a week, the truth is that you're working a helluva lot of hours. That's 10-hour days six days a week. But since 60 hours is just your basic workaholic level, and you feel like you're doing more than basic workaholic hours, you figure you must really be working 70 or 80 hours a week.
There are some people who really do work these kinds of hours, of course. And there are people who work multiple jobs and put in lots of hours. But among your typical hardworking office types, bragging on your hours comes with the territory. As with other kinds of bragging, however, you should take it with a grain of salt.

Nobel economics prize goes to two Americans: Lloyd Shapley, Alvin Roth

Nobel economics prize goes to two Americans: Lloyd Shapley, Alvin Roth

By Updated: Monday, October 15, 8:46 AM

Two researchers whose work has made for better matchups among students and the schools they wish to attend, and between kidney donors and recipients, were awarded the Nobel Prize in economicsMonday.
Lloyd Shapley and Alvin E. Roth will share the $1.2 million prize for work that broke new theoretical ground (in the case of Shapley) and resulted in concrete uses for that theory (developed by Roth). It is an award that is not terribly relevant to the great macroeconomic crises of the day but that honors work that provided a deeper understanding of how markets work and put that knowledge to use for the practical benefit of humanity.
“The combination of Shapley’s basic theory and Roth’s empirical investigations, experiments and practical design has generated a flourishing field of research and improved the performance of many markets,”the Nobel committee said in its announcement awarding what is formally known as the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel.
Shapley, a professor emeritus at UCLA, developed a theory of “matching methods,” for how to best to match people up in large groups of, for example, men and women considering marriage. The goal is to ensure that the system is “stable,” that both partners feel that they have gotten the most attractive possible match; otherwise, they might separate in search of something better.
Shapley and colleague David Gale developed a process for ensuring that those matches are as stable as possible. In the process, known as the “Gale-Shapley algorithm,” there are a series of rounds in which men and women rank potential mates, and matches are made until everyone finds a spouse and the system is stable.
That work was purely theoretical — no marriages were arranged through the algorithm. But years later, Roth, now at Stanford University, developed ways to apply Shapley’s work to practical uses. The earliest and most widespread was in the system used to match new medical residents with hospitals that wish to employ them.
Roth first recognized that the National Resident Matching Program, which attempts to ensure that new doctors and the hospitals looking to hire them can get as good a match as possible, closely matched the Gale-Shapley algorithm. After all, an employer and employee trying to find the best match are in many ways similar to a hypothetical husband and wife looking to match up.
Roth then helped the resident matching program adapt its process to deal with couples who wished to ensure that they be hired by hospitals in the same city and to make the system less prone to manipulation by participants trying to game the system.
New York City schools faced similar problems in their old system for matching students with schools; students listed their preferred schools, but the system was prone to manipulation when less-qualified students could improve their odds of getting into a school by ranking it higher than they really viewed it.
Roth helped the schools revamp the system, using the lessons from the resident matching program and the theoretical work by Shapley. The result, according to materials from the Nobel committee, was a 90 percent drop in the number of students who were assigned to a school for which they had expressed no preference.
The field of “matching” has life-and-death consequences as well. Research is underway on applying the Gale-Shapley algorithm to the challenge of matching up kidney donors and those who need a transplant. This is a field with particular complications, as many willing to give a kidney to a loved one are not a match, so multi-direction trades can be useful — but that requires a complexity far beyond the original Shapley work in the 1960s or Roth’s efforts to put it to work in the 1980s.
“Some say economics has all kinds of good tools and techniques, but it has an absence of interesting problems,” Roth, 58, told Forbes magazine in 2010. “I look around the world, and I see all kinds of interesting, important problems we ought to solve with the tools we have.”

SWMM 5 Control Rules for Pumps

Subject:  SWMM 5 Control Rules for Pumps

If you want to define the setting for a pump between the Pump On and Pump Off depths then an IF statement based on the Pump flow will work better as in this example, which changes the setting for the pump between a depth of 18 and 20 meters.   The IF statement based on flow will ensure the rule only applies when the Pump Control depth is moving from the Pump On depth to the Pump Off depth and NOT between the Pump Off and Pump On depth.  Figure 1 shows how the Pump Flow is related to the Pump Setting.

RULE CONTROL_Rule2
IF PUMP PUMP1 FLOW > 0.000000
AND NODE WELL HEAD > 18.000000
AND NODE WELL HEAD < 20.000000
THEN PUMP PUMP1 SETTING = 0.700000
PRIORITY 2.000000
