How to Draw the Top Width in @INNOVYZE #InfoSWMM for Transects OR HEC-RAS Open Channels

Here is a procedure that works for me to draw the top width for transects from the InfoSWMM model results: Make a map display of the maximum top width during the simulation, the variable is MXTOP_WIDH and will added to the Arc Map TOCUse the Buffer Command in Arc Map and a field of MXTOP_WIDH the Buffer Command in Arc Map and the Pipe or Link feature classI have Arc Map Standard so I cannot use Create Polygons from Lines or Advanced Editing which might work for you is a buffer polygon made with a different width for each link

Weekday and weekend hourly time patterns for Dry Weather inflows are now correctly applied in a mutually exclusive manner in #SWMM 5.1

This is a code note about change 52 in the newer EPA SWMM 5.1.x C code

52. Weekday and weekend hourly time patterns for Dry Weather inflows are now correctly applied in a mutually exclusive manner.

 Here is the code from SWMM 5.0.022
double inflow_getDwfInflow(TDwfInflow* inflow, int month, int day, int hour) // //  Input:   inflow = dry weather inflow data structure //           month = current month of year of simulation //           day = current day of week of simulation //           hour = current hour of day of simulation //  Output:  returns value of dry weather inflow parameter //  Purpose: computes dry weather inflow value at a specific point in time. // {     int    i,                          // pattern type index            p;                          // pattern index     double f = 1.0;                    // pattern factor
    for (i=0; i<4 i="" o:p="">     {         p = inflow->patterns[i];         if ( p >= 0 ) f *= inflow_getPatternFactor(p, month, day, ho…

GUI Compilation Note for the #SWMM 5.1.x Delphi Code

This is for Students who want to make their own customized version of the SWMM5 GUI Interface. You can use the Embarcadero Starter Version for XE2 to XE7.  Here are the main files you download from the EPA There may be a problem with teechart and the starter version - see the note here  I got it work in XE7 but I did have to remove XPPRINTER references from the Delphi code.  


Note from the EPA: This archive contains source code for the Windows graphical user interface portion of Version 5.1.007 of the Storm Water Management Model (SWMM). The interface was written using Embarcadero's Delphi XE2 ( The name of the Delphi project containing the code is Epaswmm5. All of the files for the project can be found in the GUI5_1_007.ZIP file within this archive.

Before the Epaswmm5 project can be loaded into Delphi's Integrated Development…

EPA SWMM Build 5.1.007 (9/15/2014) with New Feature Images

SWMM 5.1 Update History ======================= Build 5.1.007 (9/15/2014)
Engine Updates, more information and code shown on the EPA Website:
1.   A new feature that provides monthly adjustments for      temperature, evaporation rate, and rainfall was added.

2.   Support for reading the new GHCN-Daily climate data      files available from NCDC's Climate Data Online service      was added.
3.   In addition to lateral groundwater flow, a custom      equation can now also be used for seepage flow to      a deeper groundwater aquifer.

4.   The [GW_FLOW] section of the project file was renamed      to [GWF] and its format was changed to accommodate      both lateral and deep groundwater flow equations.
5.   A new Weir parameter was added that specifies if the      weir can surcharge using an orifice equation or not.      Surcharging was the only option in SWMM 5.0 but was      switched to no surcharging in earlier 5.1 releases.      This new parameter accommodates both closed top weirs      that can surc…

Transects in InfoSWMM and SWMM5

Transects in #InfoSWMM and #SWMM5
There is only one transect per link and the shape stays the same from the  upstream to the downstream nodeThe links are irregular channels with the name of the imported HEC-RAS transect defining the shape of the transect (Bullet 1)The transects are converted from the station/elevation pairs to normalized depth and width tables (Bullet 2)The inverts used for the links are independent of the station/elevation pairs, if the offset is zero then the  invert of the link equals the invert of the upstream or downstream node (Bullet 3)The normalized tables are shown in the text report file (Bullet 4)If the node depth or rim elevation is lower than the depth of the transect the depth is increased internally in the engine (Bullet 5)If you only have one transect for the culvert you can assign the same transect name to both the upstream and downstream irregular links
