Note:   How to Understand the OUT directory in InfoSWMM and H2OMAP SWMM This is how you understand the files in the .OUT directory: .OUT                         OUT directory of the InfoSWMM project Scenario                    Location of all Scenario Output Files Base                         The Base Scenario in this case JOB                           The temporary output file for inp, out and txt files during the simulation –                             ...

Note:    The minimum travel distance in an InfoSewer or H2OMap Sewer model can be related to the mean link length in the Pipe DB Table.  Here is a table of the Mass balance check for one network versus the minimum travel distance in feet for the default values of network accuracy, minimum time length and maximum number of segments at a report time step of 1 hour.   As you can see making the Minimum Travel equal to the mode of the length histogram yields the best results even for the default model parameters. Minimum Travel Distance Mass Balance Check: Label 1 10.50 (%) 5 3.25 (%) 10 6.25 (%) 20 17.34 (%) 25 7.05 (%) 30 1.38 (%) 40 1.07 (%) 50 1.07 (%) 55 1.05 (%) 58 3.87 (%) 60 3.34 (%) 75 0.55 (%) 80 3.09 (%) 90 11.60 (%) 100 17.20 (%) 200 17.34 (%) 1000 17.34 (%)

Note:   InfoSWMM Solution Options in Windows 7 1.    32 bit or 64 bit solution engine based on SWMM 5.0.022 selected using the Tools/Preferences/Operation Settings command 2.    Number of dynamic solution threads for parallel processing selected using the Run Manager, 3.    Single or batch runs selected using the Run Manager, and 4.    DLL or the Simulation Task Manager using the Tools/Preferences/Operation Settings command. You have control over the type of engine, the number of threads, the number of runs and whether the run is started right now or scheduled to run later or in batch mode (Figure 1).

------------------------------------------------------ EPA SWMM 5 Build 5.0.022 (04/21/11) ------------------------------------------------------ Engine Updates 1. The following fixes and updates were made to the LID module of the code (lid.c): a. The Drain Delay time for a Rain Barrel LID is now correctly converted internally from hours to seconds. b. The meaning of the Conductivity property of an LID's Storage layer has been changed. It is now defined as the saturated hydraulic conductivity of the native soil below the layer instead of the conductivity of the layer itself. c. Storage layers are now optional for Bio-Retention Cells and Permeable Pavement LIDs by allowing the layer height to be zero. One should still enter a non-zero conductivity for the layer if infiltration into native soil is allowed. d. If the top width of the overland flow surface for an LID is zero then any excess water above the surface storage depth simply spills out instantaneously. e. The calculation of i...

Innovyze Launches New Product and New Name at Asia Pacific Conference IWLive Introduced to Rave Reviews at the Asia Pacific Water and Sewer Systems Modeling Conference Broomfield, Colorado USA, May 3, 2011  —  Innovyze, a leading global innovator of wet infrastructure modeling and simulation software and technologies, recently concluded its annual Asia Pacific Water and Sewer Systems Modeling Conference in the Gold Coast, Australia. The conference was the first public event for the company under its new name, Innovyze. It also introduced the firm’s newest product,  IWLive , to the Asia Pacific water community.  “The Asia Pacific 2011 conference was great. Very well organized and executed. [The] team did a fantastic job.  The atmosphere and culture were great and this made the conference very enjoyable, informative, and motivating,” commented Stuart Sargent, Services Development Engineer for Marlborough District Council in New Zealand. The highlight of the confer...

Problem:   The network looks very small when you zoom out to the maximum extents of the window Step 1:   Zoom out a few times to a visible network Step 2: ArcGIS View/Data Frame Properties/Other / Current Visible Extent will fix your network view.  

Note:  Why isn’t the “Ground Elevation” of the Junctions listed in the “Junction Information” table of the DB Editor? The ground elevation is listed in the Junction Hydraulic Data DB Table under: 1.    Max Depth if Store Absolute Junction Rim is off in Tools/Preferences/Operation or 2.    Junction Rim Elevation in the same column of the DB Table if Store Absolute Junction Rim is on in Tools/Preferences/Operation 3.    It is not listed in Junction Information which is designed for user extra input data. Figure 1.  Rim Elevation for Nodes instead of Maximum Depth Figure 2. Maximum Depth instead of Rim Elevation for Nodes.
