Two Pass InfoSewer Solution

Two Pass InfoSewer Solution
The d/D you are Mapping is from the 1st pass or the solution in which the manhole loads are calculated and the program estimates the flow in the links – the flow gives the value of d/D which you are mapping.The HGL plot is plotting the adjusted d/D which is the result of the 2nd pass of the solution, this pass estimates backwater, surcharge and pressure and often the value of the Adjusted d/D is higher than the 1st pass value of d/D.The Adjusted d/D is a better way of finding those pipes that are more than 0.75 full.

Massive Flooding In Alberta Canada Forces 75,000 To Flee By Rebecca Leber posted from Climate Progress on Jun 22, 2013 at 3:00 pm
Alberta, Canada. Credit: AP Parts of Alberta, Canada were hit by extreme flooding the size of New York State on Friday, forcing 75,000 to evacuatetheir homes. Hit by heavy rain, people have abandoned their cars and low-lying residences in flooded waters Mayor Naheed Nenshi described as “an ocean at the moment.”
Across the world, cities in Germany have also been wrecked by flooding — one estimate puts the damage as high as $7.7 billion. Climate science explains that global warming leads to a 5 to 10 percent increase in rainfall, and subsequently leads to a higher risk of flooding. As Climate Central notes in its reporting on the Calgary floods: “A study published in the journalNature Climate Change on June 9 found that flood frequency as well as the number of people at risk of inundation from flood events are both likely to increase as the world continues to…

How to Find Duplicate Links in InfoSWMM

1.Make a table of all  From Nodes for all of the links using Conduit Information,
2.Made an output DBF table using the summary command of the Open Attribute Table of Arc Map
3.Joined the output DBF table to the Junction layer
4.Labeled all Nodes that had more than one outgoing link
5.You can see on the screen the possible duplicate links and decide which are valid and which are not allowed How to Find Duplicate Links in InfoSWMM pic.twitter.com/BUJvhIkGnd

If you have a SWMM 5 file without any X, Y  coordinates you can assume an X and a Y and then use Excel to make each pair random by using the RAND() function.  You at least will see each of the nodes on the screen with associated links.

Wikipedia Traffic for the SWMM versus EPANET Articles

Image
Subject:WikipediaTraffic for the SWMMversusEPANETArticles
Wikipedia has one article for EPANET and three articles for SWMM 5 (two are redirected to the Stormwater Management Model Main Article).  The statistics for the last three years (data before 2007 is unavailable) show an average of 28 visitors per day to SWMM and 16 per day to EPANET).  The search name has switched from the word SWMM to Stormwater Management Model starting in 2009.
