Two new parameters and a modified table in InfoSWMM 11 and H2OMAP SWMM

Subject:  Two new parameters and a modified table in InfoSWMM 11 and H2OMAP SWMM that does the following:

 

1.   Allows you to control the maximum number of iterations in the solution,

2.   Controls the Stopping tolerance (units of feet) for node iterations, and

3.   Shows not only the percent continuity error at a node but the error in million gallons (Mgal)

 

If you have a high continuity error or want to reduce your existing continuity error then you can increase the number of iterations or lower the stopping tolerance so that at each time step there is less continuity error.

 

 

 

Iterative Hot Start File

Subject:  Iterative Hot Start File

 

1.       If the continuity error is due to the lack of a hot start file,

2.       You should make the hot start file iteratively,  or successively Save and Use two hot start files until the initial and final stored volume is about the same in the flow routing continuity table,

3.       1st Step: Save Hot Start File 1,

4.       2nd Step: Use Hot Start File 1 and Save Hot Start File 2

5.       3rd Step: Use Hot Start File 2 and Save Hot Start File 1 and

6.    Repeat until the initial and final storage volume is about the same

 

The Economics Of Attention

Subject: A good post from Matt Yglesias about trades which do NOT become more productive over time - trades that involve paying attention to your fellow humans

The Economics Of Attention

One of the most important things about the health care and education segments of the economy is that part of what customers want is attention. Parents like the idea of small class sizes, and patients like the reassuring face-to-face presence of a doctor with a good bedside manner. But personal attention has the pretty special characteristic of being immune to productivity enhancements. This creates the following trilemma as economy-wide productivity rises:

— One: The wages of teachers and doctors can fall relative to average wages, because teachers and doctors aren’t increasing their productivity as rapidly as the average worker.

— Two: Paying the salaries of teachers and doctors can account for an ever-growing share of national output, because the rest of our output is getting more efficient and teaching and treating isn’t.

— Three: The amount of attention provided by teachers and doctors to students and patients can decline.

It’s not that you need to pick one of those three things, but you can’t pick zero of them. And it’s not that three necessarily needs to mean declining educational and health outcomes. Attention is important to people, subjectively, but it’s hardly the only thing that matters for learning and it’s definitely not the only thing that matters for health. If doctors spend less time with their patients but are able to prescribe more effective drugs, that’s a net benefit. And it’s possible to increase reliance on less-trained kinds of medical professionals who are paid less than doctors but may still be competent to perform attention-paying functions. On instinct, though, people’s preferences are for smaller classes, more face time with doctors, and more of a sense of personalization and customization. I still hear older people sometimes reminisce about the doctors of yore who’d pay house calls, hardly noticing that this inefficient use of medical professionals’ time just reflects low economy-wide productivity.

I find that a frustratingly large share of discussions of these issues involves too much talk of dollars and cents and not enough qualitative talk along these lines. That allows people to avoid saying what they mean. Hold the growth of federal health spending to the rate of inflation? Sounds great! But what does it look like? If the bottom third of the income distribution stops being able to afford to see the doctor, that frees up more doctors’ time to pay attention to richer people. So that’s one possible answer. But if that’s what you mean, that’s what you should say. And if you think we need to increase the relative wages of teachers while further shrinking class sizes and sustain that policy over time, it’ll mean steadily increasing taxes, no one-off increase will undue the Baumol Effect. That’s one possible answer—America is lightly taxed compared to other rich countries—but you owe it to yourself at least to face up to that.

 

InfoSWMM Map Display of Scenario Differences

Subject:  InfoSWMM Map Display of Scenario Differences

 You can also make a table and map of the differences between the existing and future scenario.  The red in the image shows the pipes in which the flows have increased and the blue shows the pipes in which the flows have decreased between the existing and future scenarios.  You make the table by

 1.       Making a conduit report for both scenarios at the same date/time,

2.      Copy the flow in the link for all links to Excel and make a new column with the difference between the future and existing conditions,

3.      Make a new column in the Conduit Information Table of InfoSWMM for real data and  paste the new column from Excel into the  Conduit Information Table,

4.      You then can use Map Display for links and show a Map Display of the flow differences at that particular date/time for all the links. 

  

MWH Soft Changes Name to Innovyze


MWH Soft Changes Name to Innovyze 

New Name Reflects Company’s Unique Water Modeling and Management Offerings and History of Innovation

Broomfield, Colorado USA, March 27, 2011 — MWH Soft is pleased to announce it has a new name, Innovyze. The new name and logo more accurately reflect the company’s rich history of creating innovative, technically advanced modeling and management solutions for the world’s water and wastewater communities.
