H2OMAP Sewer and InfoSewer Water Quality Options
The SWMM 5, 1D Components in InfoSWMM 2D
Note: The SWMM 5 1D Components in InfoSWMM 2D
Note: The SWMM 5 1D Component
InfoSWMM 2D uses standard SWMM 5 components to connect the 1D Nodes to the 2D Mesh. A bottom outlet orifice at the maximum depth of the node drains to a SWMM 5 Outfall at the fixed elevation equal to the Node Rim Elevation. Flow can go into or out of the Outfall from the 1D element from or to the 2D Mesh. InfoSWMM 2D
The HYDQUA.inp is very similar to the Excel Tab formatted file of SWMM 5 with a few additional sections and added features:
1st Difference: The Flood Node Data Section tell the 2D engine which Node has a 1D-2D connection and which 2D mesh element the 1D Node drains to when it is flooded.
[Flood_Node]
10309D 848
80408 131
2nd Difference: Outfall Nodes are created for the 2D Mesh Element connected to the 1D Node, the outfalls are Fixed Outfalls and the fixed head is the Node Rim Elevation of the 1D node listed in the Flooded Node Section
[OUTFALLS]
10208 89.900000 FREE NO
10208A 89.900000
10208B 89.900000
10208C 89.900000
10208D 89.900000
10208E 89.900000
10309D_OUTFALL 101.
80408_OUTFALL 120.
3rd Difference: Bottom Outlet Orifices are created to connect the 1D node to the 2D Mesh Element Outfall with the Flood Discharge Coefficient entered by the user and a crest height equal to the maximum depth of the node
[ORIFICES]
OR1@82309B-15009B 82309B
OR1@82309D-82308D 82309D

How to Compare the Output Manager Statistics in H2OMAP SWMM to the SWMM 5 Output Text File
Subject: How to Compare the Output Manager Statistics in H2OMAP SWMM to the SWMM 5 Output Text File
Subject: How to Compare the Output Manager
The value of the total inflow in the text output file is the integrated total for the whole simulation including all time steps. This is the total volume that is shown in Map Display for Nodes and Links or in the Summary Tables for Nodes and Links. If you graph the flow or depths in Output Report Manager and use the FieldStatistics tool it will only show you the statistics for the SAVED time steps. However, if you multiply the Sum (Total) Value by the saved interval in seconds you will have another estimate of the total node of link statistic. For example, a Sum Total of L/s times seconds yields liters which divided by 1,000 yields ML.
Figure 2. Map Display of the total link volume in the model run comes from the Node Inflow Summary Table in the Text Report File

How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM from the Model Results
Note: How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM from the Model Results
Note: How to Calculate the Freeboard of a Node in InfoSWMM/H2OMAP SWMM
The freeboard for a node in InfoSWMM/H2OMAP SWMM
1. Copy the Node Rim Elevations from the DB Tables for Junctions to Excel,
2. Run the model and then copy the Maximum HGL from the Junction Summary output table to Excel,
3. Calculate the Freeboard
4. Create a new column called Freeboard in the Junction Information DB Table and paste the Freeboard from Excel.
You will be able to perform Map Displays or Map Queries now using the new Freeboard information column.

Node Comparison in InfoSWMM and InfoSewer
Note: Node Comparison in Info
1) Is there an option to set the manhole sealing method (i.e. locked
or unlocked) in InfoSWMM? You set the Surcharged depth to a positive value to prevent flooding and keep the pipes under pressure. You will still have flooding once the water surface elevation reaches the maximum depth + surcharge depth. Unlike inInfoSewer the depths are not unlimited.
2) Is defining manhole diameter in InfoSWMM available? You can set the default surface area of a node or make it a storagenode.
3) Does InfoSWMM allow me to create parallel pipes with the same
attributes similar to InfoSewer? You can set the number of barrels in the attribute browser of DB Editor in InfoSWMM.
4) Can you please confirm that the only element allowed to leave a
storage unit in InfoSWMM is a pump? No, this is not true. You can have a gravity main, orifice or weir leave a storage pond or lake.
5) Is there a tool to check for pipe diameter discrepancies in
InfoSWMM similar to InfoSewer? Yes, we have a similar Engineering Review and Network Audit Tools
6) For load patterns, I do not see an option between stepwise and
continuous in InfoSWMM, or is there? InfoSWMM really only has stepwise linear DWF pattern though you can have a time series of inflows as well which gives you complete flexibility.
7) Does InfoSWMM offer modeling I&I using pipe length, pipe surface
area etc… like in InfoSewer? You can but there in not an easy translation, You have Rainfall Induced Infiltration at a Node. You can relate this to the pipe length but it is not straightforward.
8) Is steady state simulation and design simulation available in
InfoSWMM similar to InfoSewer? You can do Steady State easily but design uses a Genetic Algorithm technique if you have InfoSWMMSuite.

Subject: InfoSewer and H2OMAP Sewer New Features in 2011
Subject: InfoSewer and H2OMAP
InfoSewer for Arc GIS 9 and 10 and H2OMAP Sewer had a many engine and GUI enhancements during 2011 to allow the programs to work better for models up to 50,000 elements that simulate water quality and hydrology. The improvements now allow large models to be run with smaller report and simulation time steps and provide a Mass Balance Check at the end of the report file for the user to easily check the model results. The new ForceMain
