Two Pass InfoSewer Solution

Two Pass InfoSewer Solution

🔰The Two-Pass InfoSewer Solution method refines the estimation of flow within sewer networks by employing a dual-stage analysis. Initially, in the first pass, the system calculates the loads at each manhole and subsequently deduces the flow in the connecting links. This initial flow estimation is utilized to determine the preliminary depth-to-diameter ratio (d/D), the values of which you are presently mapping.

🔰Subsequently, the second pass of the solution process takes place. This stage is critical as it accounts for complex hydraulic phenomena, including backwater effects, surcharge conditions, and pressurized flow. It is during this phase that the depth-to-diameter ratio is adjusted, often resulting in an increased d/D value compared to the initial pass. This adjusted d/D is depicted in the Hydraulic Grade Line (HGL) plot.

🔰Utilizing the adjusted d/D from the second pass provides a more accurate indication of pipeline capacity and performance, particularly identifying pipes operating at or above 75% fullness. This metric is essential for effective sewer system management, offering a clearer insight into the potential for overflow and the need for infrastructural intervention.

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

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 warm.”

Heavy precipitation extremes, which sometimes result in river flooding, have been increasing in much of the U.S. east of the Mississippi River. Credit: Climate Central.

Alberta is home to controversial tar sands development, where the city of Calgary happens to be a source of climate denier arguments: The Calgary Herald, an influential paper in western Canada, has spouted climate denier points on its editorial page. The University of Calgary, meanwhile, was once paid to distribute resources opposing climate change science.

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 Use Excel to Make Random X, Y Coordinates in SWMM 5

Node	X	Y	Rand X	Rand Y
A	2465753425	-1799501868	1114137518	-1734364827
B	1220423412	-915317559.2	959332294.5	-427183555.6
C	1207970112	-2970112080	939805860	-417442286.9
D	-485678704.9	2970112080	-172000249.5	1835904922
E	-2789539228	1388542964	-2050647732	326604825.1
F	-4221668742	-130759651.3	-3537896272	-59872442.99

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

Subject:  Wikipedia Traffic for the SWMM versus EPANET Articles

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.
