Manhole Elevations in InfoSWMM and SWMM 5

Manhole Elevations in InfoSWMM and SWMM 5
Subject: Manhole Elevations in InfoSWMM and SWMM 5
Starting from the bottom of the manhole you have these regions of computational interest:
1.   Manhole Invert to the lowest link invert – the node continuity equation is used with the area of the manhole being the default surface area of a manhole,
2.   Lowest Link Invert to the Highest Link Crown Elevation – the node continuity equation is used with surface of the node being normally half of the surface area of the incoming and outgoing links,
3.   Highest Manhole Pipe Crown Elevation to Manhole Rim Elevation – the node surcharge algorithm in which the surface area of the manhole is not used and the surcharge depth is iterated until the inflow and the outflows of the node are in balance,
4.   The region above the Manhole Rim Elevation which can use one of four options to calculate the depth and/or flow out of or into the manhole:
1.   No Surcharge Depth is entered and No Ponding area is used – the excess water into the manhole is lost to the network and shows up as internal outflow in the continuity tables,
2.   A Ponding Area is used and the excess flow will  pond on the surface of the manhole and later go back down into the conveyance pipes.
3.   A Surcharge Depth is used and the depth will continue to be calculated using the node surcharge algorithm in which the surface area of the manhole is not used and the surcharge depth is iterated until the inflow and the outflows of the node are in balance,
4.   A Dual Drainage system is simulated and the excess flow of the manhole is simulated in the street gutters or the actual street,
5.   You use a 1D/2D linkage between the 1D manhole and 1D links to a 2D Mesh and simulate the flow out and the flow into the manhole using a bottom outlet orifice that switches automatically between weir and orifice flow based on the depth on top of the manhole.

How to Import the SWMM 5 Report File as a Layer in infoSWMM


How to Import the SWMM 5 Report File as a Layer in infoSWMM


Subject:  How to Import the SWMM 5 Report File as a Layer in infoSWMM
The idea of this blog of note is to show how one may extract information from the SWMM 5 or InfoSWMM RPT file and import the Excel  File as a feature in InfoSWMM.  This blog has an example Excel file to illustrate the linkage. The steps are:
Step 1:  Copy the whole row  from Conduit Summary from the InfoSWMM Browser  
Step 2:  Add the two columns length and  slope from the Link Summary Table and the InfoSWMM Browser  
Step 3:  You need a few calculations based on the table values from SWMM 5 to estimate the CFL  time steps in the .  
Step 4:   Add the Excel Spreadsheet as a layer in InfoSWMM – the Named Range should be added to insure valid numbers and not Nulls after the join  
Step 5:  You can now plot the CFL Time Step for the Links using the Layer Properties command in Arc Map 
Step 1:  Copy the whole row  from Conduit Summary
Step 2:  Add the two columns length and  slope from the Link Summary Table
Step 3:  You need a few calculations based on the table values from SWMM 5 to estimate the CFL  time steps.
The CFL Step      = Length / (Full  Velocity + (Gravity * Full Depth)^0.5)
Full Velocity        = Full Flow / Full  Area
You also need to create a Name A Range for you data so that the data does not show up as Nulls
 Step 4:  Add the Excel Spreadsheet as a layer in InfoSWMM – the Named Range should be added
Step 4:  Join the Excel  Table to the InfoSWMM Conduit Feature Layer
Step 5:  You can now plot the CFL Time Step for the Links using the Layer Properties command in Arc Map

World-Renowned Urban Drainage Modeling Authority Robert Dickinson Joined Innovyze in January, 2008

World-Renowned Urban Drainage Modeling Authority Robert Dickinson Joined Innovyze in January, 2008

Broomfield, Colorado USA, January 16, 2008/altered 2014

2008/2014 Robert E. Dickinson, one of the world’s leading experts in wastewater and urban drainage modeling, has joined Innovyze as Product Sector Leader. Dickinson, who comes to the company from CDM now CDMSmith, will be charged with maintaining, enhancing and supporting Innovyze's flagship SWMM5-based product line (InfoSWMM and H2OMAP SWMM as well as the GIS based InfoSewer and H2OMap Sewer), which are some of the industry’s leading wastewater and urban drainage systems design and modeling software. He will also be responsible for coordinating vital collaborative research and technology transfer with key universities and government organizations as well as developing business strategies that advance Innovye’s overall growth objectives in wastewater and stormwater systems management and heighten its initiatives in both U.S. and international markets.

Mr. Dickinson brings over thirty-five years of experience in software development and management of wastewater and stormwater planning and design projects to Innovyze. A principal developer of the industry-standard and FEMA-certified SWMM5 software, he has a distinguished background in computational hydraulics and high level simulation programming. He holds an M.E. degree in Environmental Engineering from the University of Florida, Gainsville.

“We are thrilled to bring Robert’s formidable talents and expertise to our company,” said Innovyze's President and COO Paul Boulos. “As one of the world’s leading experts in hydraulic and hydrologic modeling, he has made significant contributions to the field of water resources engineering. His unique combination of proven project engineering expertise, management skills and high-level technical capabilities is coveted in our industry.
“A number of factors make Robert the ideal leader to help Innovyze advance the state-of-the-art in dynamic sewer network modeling and spearhead the continued development of our SWMM5-based products family. They include his impressive record of leadership, impeccable reputation, key role in the USEPA Storm Water Management Model (SWMM5) redevelopment program, strong expertise in both numerical methods and hydrology/hydraulics, and in-depth knowledge of the wastewater industry.

“While he will be based in Tampa, Florida, Robert will work closely with our product development team and our clients as we step up our efforts to help communities around the world manage urban runoff and wet weather water quality problems in combined, sanitary and storm sewers and protect the ecological health of our waterways.”

“I am truly excited to be joining Innovyze,” said Dickinson. “For the past five years, I have followed the company’s rapid growth and development of an impressive product portfolio. I have always admired Innovyze’s unparalleled technical expertise and its steadfast commitment to research, innovation, product quality and customer care. I believe a breakthrough approach to systems modeling is a critical key to helping communities better manage and operate their buried hydraulic infrastructures and protect the environment. I look forward to playing a pivotal role in advancing Innovyze’s comprehensive urban drainage design and modeling product line and maintaining its leadership in the global wastewater industry.”

2014 - That was fun - an update of an announcement from the past.  The original is on our website. I changed my name from Bob to Robert, the company name from MWHSoft to Innovyze and list my my actual job or jobs I have been doing at @Innovyze from 2008.  I left the title alone - sometimes it is best to have a goal in life and trying to achieve the title of the announcement is something I would like to approach in my remaining Innovyze years.  I probably will not reach it but I appreciate the mastery of the Paul Boulos announcements - he writes the most creative and wonderful press releases. You should subscribe to them from www.innovyze.com if you want to read about the future of water, sewer and stormwater.  A final mention of Alight Tsai who manages http://www.innovyze.com/ and is always helpful with great images for our software and help files.  I would be remiss if I did not mention our great R/D product development teams in Monrovia and Wallingford. I am proud to be a small part of the Monrovia team.  Other history mentions about SWMM3/4/5 in my past can be found here http://www.swmm5.net/2012/05/my-history-with-various-versions-of.html

Another update for May 2015 - we are making great strides in social media led by our Director of Marketing Rajan Ray who can be found at @InnovyzeRaj and in general at @Innovyze. You can see all of our tweets by searching for Innovyze on Twitter
