Tip for The Ponding Allowed Option in SWMM 5

Tip for The Ponding Allowed Option in SWMM 5

Normally, it is better to have smaller ponding allowed area in SWMM 5 due to considerations outlined in this earlier blog and 2nd Blog but if you have a low lying area with ponding allowed it is better if you have a larger ponding area so that the depth above the rim elevation of the node is small and you do not set up reverse  flow and cause flooding at other modes due to the  higher HGL.  Figure 1 illustrates a typical HGL profile and Figure 2 shows the better flooding  graphs as you increase the ponding surface area for the low lying node.

How to Make an InfoSewer or H2OMap Sewer Model from SWMM5

Innovyze has a broad range of programs which you can see on but each of our programs has many ways to import and export model data between programs.  All of our products have CSV and shapefile import and export.  One way to use a SWMM 5 model in H2OMap Sewer or InfoSewer is to import CSV files from H2OMap SWMM or CSV file constructed using SWMM 5.  In H2OMap Sewer you can import:
1. Manhole
2. Pipe
3. Outfall
4. Pump
5. Wet Wells
6. The DWF values can  copied to the Other Loading DB Table
7. DWF Patterns can be copied and pasted into the Pattern Tables in H2OMap Sewer and InfoSewer

Older SWMM3 and SWMM 4 Fortran Engines on Box

For the sake of history and future student reconstruction of the past of SWMM  modeling I have put on Box many copies of SWMM3 and SWMM 4 FORTRAn engines, SWMM 3 to SWMM 4 converters - updated from the EPA download page version, SWMM 4 DOC files (they are annotated text files)

How to Search Twitter for Links connected to SWMM5, #nfoSWMM or InfoSewer via @RDICKINSON for @INNOVYZE

If you have a lot a tweets as I do you can get lost in the tweets despite hootsuite, tweetdeck and other helpful aids.  You can search for a topic using Advanced Search in Twitter (Figure 1) or use a search URL with the search terms and the twitter source in the name to see the found links (Figure 2)

In addition we also have a PDF file in the InfoSWMM Help File directory called InfoSWMM Applications Guide.pdf which will help from the EPA SWMM 5 applications manual

CSV File DWF Suggestion for Importing SWMM5 Flows to ICM

If you are importing a SWMM 5 File into InfoWorks ICM one problem you will have how to deal with difference in dry weather flow generation (DWF):

1. SWMM 5 has DWF enter at a node and ICM has DWF as part of the Subcatchment Loading
2. Thee Import and Export From ICM needs manual adjustment of the DWF
3. One way to do this is to make an ICM CSV file to import the DWF Section of SWMM 5 (Figure 1)
4. Which allows you to manipulate the flow DWF in SWMM 5 to the population based DWF in ICM and IWCS.

Here is one example
hw_subcatchment,  S012-010 ,4.14841
hw_subcatchment,                   S005-005#1,7.8094
hw_subcatchment,                   S005-006#1 ,7.8094

2014 Stormwater & Urban Water Systems Modeling Conference, Toronto, Canada, February 26-27, 2014

47th Annual International Conference
Toronto, Canada
February 26-27, 2014

Interested in any aspects of urban drainage or watershed engineering? Do you use computer models in your work?
If so, you should consider attending this conference, where you will hear about 50 presentations related to your interests, and talk to over 100 like-minded, friendly and thoughtful professionals.

The annual International Conference on Urban and Rural Water Systems Modeling is a forum for professionals from across North America and overseas to exchange ideas and experience on current practices and emerging technologies. This is the 47th annual SWMM Users Group Meeting, the 23rd in the current series of annual Toronto conferences, and the 34th to be held in Canada. The atmosphere is relaxed, presentations are of a high standard and by accepting papers up to the last few weeks before the event, a spontaneity is achieved which gives this conference special character.

InfoSWMM 2D Inflows and Mesh Element to 1D Node Linkages

The 2D Output HTML file of InfoSWMM 2D shows the Total 2D Inflows at each node by Mesh ID.  You can either graph, report use the 2D Graphs in InfoSWMM to also see these flows but in addition there is a Section in the 2D InfoSWMM input file (Hydqua.inp) that shows the 1D Node Name followed by the Mesh Element ID (Figure 1)

Net inflow in 1d nodes Node id : 2919 // Net Inflow (m3) : 15244.2504 Node id : 2946 // Net Inflow (m3) : 7429.7630 Node id : 7405 // Net Inflow (m3) : 0.0000 Node id : 7451 // Net Inflow (m3) : 699.8173 Node id : 4022 // Net Inflow (m3) : 4026.5423 Node id : 2370 // Net Inflow (m3) : 2076.7189 Node id : 1083 // Net Inflow (m3) : 5697.8787
