InfoSWMM v11.1 Changes to Date

InfoSWMM v11.1:

Support ArcGIS 10.1.
InfoSWMM or H2OMAP SWMM import: corrected the typos in error messages. (HsHxfSvr.dll, N/A, 6/22/2012)
Improvement: for better hours/minutes listing in Report Manager Report Table for Continuous Simulation with Odd Report Time Step Intervals.  For example, this fix improved the output time display for irregular (in

60 minute sense) output time steps.  Now it displays 00:50, 01:40, etc. more correctly than before (00:49, 01:39, etc). (HsOutPkg.dll, N/A, 6/21/2012)
Improvement or Bug Fix:
Added an IF statement to the RDII Unit Hydrograph Convolution for the  rare instances in which the user sets the time base of the UH to zero by setting either T or K to zero.  The Time Base is T*K in the

convolution integral and zero values are not allowed.  This bug was also forwarded to the EPA for a future SWMM 5.  The convolution uses the value of R and the Time Base to estimate the amount of Infiltration and

Inflow in the Sewer Network.  The short, medium and long term UH’s are estimated at each Wet Hydrology time step to make a smooth hydrograph out of the R, T and  K parameters of the Rainfall Dependent Infiltration

and Infiltration Method. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/21/2012)

Improvement: More information for the user when one of nine SWMM 5 warning messages are listed in the HTML Output File. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/21/2012)
                These are the nine SWMM 5 Warning Messages
                "WARNING 01: wet weather time step reduced to recording interval for Rain Gage"
                "WARNING 02: maximum depth increased for Node"
                "WARNING 03: negative offset ignored for Link"
                "WARNING 04: minimum elevation drop used for Conduit"
                "WARNING 05: minimum slope used for Conduit"
                "WARNING 06: dry weather time step increased to the wet weather time step"
                "WARNING 07: routing time step reduced to the wet weather time step"
                "WARNING 08: elevation drop exceeds length for Conduit"        
                "WARNING 09: time series interval greater than recording interval for Rain Gage"
                And Here is the Extra Information Now Saved to the HTML Output File in case the user wants to know what is used internally in the engine.  This is especially handy information when moving a SWMM 5 model to

                IWCS or ICM.
Application Framework: introduce the new “Inherited” Facility Set option.  Scenario can now inherit facility selection from its ancestor which possesses a non-inherited facility definition. (HsCadPkgPkg.dll,

HsUI2Pkg.dll, and HsDBBPkg.dll, N/A, 6/21/2012)
                                       New Option in DB Tables for Scenarios

The export to the hydqua.inp file when you solve a H2OMAP SWMM model now includes the infiltration data even if the Subcatchment DB Infiltration column is blank after the import of a SWMM 5 file.  The blank row

defaults to the global Infiltration option in Base Simulation Options. (HsDataPkg.dll, N/A, 6/14/2012)
Eliminated a duplicate graph of storage infiltration in the Low Impact Development. (HsOutPkg.dll, N/A, 6/14/2012)

Implemented a future EPA fix for infiltration loss on a pervious surface if snowmelt is being simulated.   This fix will be part of SWMM 5.0.023. (HsEngPkg64.dll and HsEngPkg.dll, N/A, 6/13/2012)
The error was the double counting the accumulation of snow cover as infiltration in the mass balance table – here is the mass balance without the fix in SWMM 5.0.022

Fixed the problem of Edit Domain Attribute.  It was caused by a table relate issue in DB engine. (HsMapSrv10.dll, N/A, 5/29/2012)
Recompiled to fix a compatibility issue of the validation tool. (HnUtl.dll and HsUtlSrv.dll, N/A, 5/29/2012)

Fix flowchart run issue. (HsCIPSrv.dll, N/A, 5/29/2012)

InfoSWMM v11 Update 10:

Changes & Improvements

Fix subcatchment vertex export issue for EPS-SWMM. (H2OSWMM.exe, N/A, 4/18/2012)
Scenario Comparison: Now, the “Hide Unchanged Column(s)” right-click command works correctly. (HsUI2Pkg.dll, N/A, 4/17/2012)
Netview Storage/Wet-Well Output: Fixed an invalid output data field problem. (HsOutPkg.dll, N/A, 4/12/2012)
Scenario Comparison: Fixed Duplicated ID Alias problem. (HsUtilPkg.dll and HsDBBPkg.dll, N/A, 4/11/2012)
Crashed Project Restoration: Now, active scenario ID could be reliably restored

Check negative GA Hydrograph solution value during export back to InfoSWMM or H2OMAP SWMM. (HsRDIIPkg.dll, N/A, 5/3/2012)

InfoSWMM v11 Update 9:

Changes & Improvements

Simulation Run Report : Added a Scenario data source reference to the title notes section of the RPT file. (HsEngPkg.dll, HsEngPkt64.dll, and HsDataPkg.dll, N/A, 3/15/2012)
Simulation Run Output Data Access: Improved 64-bit access reliability for simulation run output data. (HsEngPkg.dll, HsEngPkg64.dll, and HsOutPkg.dll, N/A, 3/19/2012)
Small Time Base fix for RDII flow to match an upcoming SWMM 5 version (HsEngPkg.dll, HsEngPkt64.dll, and HsDataPkg.dll, N/A, 3/16/2012) :
Description: SWMM 5 makes the time interval used for convoluting the unit hydrographs within a group the smaller of the wet runoff step and the smallest time to peak for the

hydrographs in the group. This works OK when all the hydrographs have rising limb durations no longer than that of the falling limb (i.e., K >= 1.0). For example, the short term

UH has a K value of 0.3, with rising limb time of 42 minutes and falling limb time of  12.6 minutes. As a result, the time interval selection rule stated above was producing too

large a time step for a wet runoff step of 30 minutes causing the convolution to ignore a good portion of the UH.  The rule was modified to compare the wet step to the SMALLER of

the time to peak and time to recede.
Importance of this  for past and future InfoSWMM and H2OMAP SWMM models:

1.            Again, it is a significant and BETTER reason to use the current SWMM 5 engine over v13 of the SWMM 5 engine,
2.            It makes the convolution more robust for a small time base in the RTK method or the Time Base= T*K
3.            It may cause RDII flow differences in this engine if T*K is small over past engines

Add Vertical Roughness to preferences dialog. (HsMapSrv.dll, N/A, 4/4/2012)


InfoSWMM v11 Update 8:

Changes & Improvements

Retain the compatible size for dialog boxes with fixed frame when user changes the screen resolution (DPI) in Windows 7. (HnUtilPkg.dll, N/A, 2/15/2012)
Support upcoming Innovyze application data folder and new product configuration file location. (HxLoader.dll, N/A, 2/15/2012)
Fix:  Improved the Change ID beep interval  for a change to the element ID using the Change ID Command. (HsUtilPkg.dll and HsCadPkg.dll , N/A, 2/4/2012)
Import of a SWMM 5 File with a Duplicate ID now tells you the name and class of object that is duplicated so it can be edited in SWMM 5.(HsDataPkg.dll, N/A, 1/31/2012):
New Feature (HEC_HMS_HYETOGRAPHS.inp, N/A, 2/2/2012): 
How to import the 44 possible SCS Storms from HEC-HMS.  The file HEC_HMS_HYETOGRAPHS.inp is imported into  InfoSWMM using the command Import EPASWMM 5 Data to import just the Raingage and Timeseries data from SWMM5.  The Timeseries data is a copy of the HEC-HMS data for each of the possible SCS Storms for SCS Type1, Type1A,  Type2 and Type3 for 1 minute, 2 minute, 3 minute, 4 minute, 5 minute, 6 minute, 10 minute, 15 minute, 20 minute, 30 minute and 1 hour intervals, respectively.   This is done so that the user of InfoSWMM has the option of using the exact HEC-HMS dimensionless precipitation for every interval and every SCS Storm Type.
New Feature (huff.inp, N/A, 2/2/2012):
How to import a dimensionless Huff distribution into InfoSWMM from using the SWMM 5 Import Command and a simple SWMM 5 file with Huff Distribution Rainfall.

Fix Final Summary Report Field Offset. (HsCIPSrv.dll, N/A, 2/29/2012)
Fix database compatibility after version upgrade for Final Condition calculation (HsCIPSrv.dll and HsCIPSrv10.dll, N/A, 3/2/2012)

InfoSWMM v11 Update 7:

Changes & Improvements

Altered the last cumulative rainfall value to use exclusively the polynomial value. (HsUI4Pkg.dll , N/A, 1/18/2011)   
The ending value for example for a 10 inch hyetograph is now

SCS1         9.9 inches
SCS1A     10.008 inches
SCS2        10.0  inches
SCS3        10.0  inches

For the 4 types of SCS Hyetographs, instead of setting the ending rainfall value to 10 inches which caused a small spike in the SCS Type 1 hyetograph for the last point in the SCS hyetograph

Fix FlowChart Analysis when project does not have CCTV data. (HsCIPSrv.dll, N/A, 1/20/2012)

InfoSWMM v11 Update 6:

Integration of Arc GIS 9.3 and Arc GIS 10.0 Installs

InfoSWMM v11 Update 5:

Changes & Improvements

SWMM 5 Export of Dry Weather Flow (HsDataPkg.dll , N/A, 10/25/2011) :
                1.            Many of our users use our DWF Allocator to assign dry weather flow to nodes based on meter data or loading areas
                2.            If they do this improperly then they may get many rows of DWF with zero flows in H2OMAP SWMM
                3.            This does not matter to H2OMAP SWMM as unlimited loads can be assigned to a node but
                4.            This is a problem in the export to SWMM 5 as SWMM 5 has a limitation of one DWF load per node
                5.            Zero DWF loads at a node are now NOT exported to SWMM 5 which makes this more compatible with the internal rules of SWMM 5
                6.            Only Non Zero DWF’s are now Exported
Fixed Dialog Display Issues for Annotation Dialog – moved label frames for overlapping frames.  Annotation is the 3rd Tab in the InfoSWMM Attribute Browser. (HsMapSrv10.dll, N/A, 10/24/2011)

Fix Validation Rule Buffer issue. (HsUI4Pkg.dll, N/A, 10/21/2011)

Fix:   A Change to the  Rule Control Status from Open/Close to On/Off for EPA SWMM 5 Control Section Compatibility. (HsUI4Pkg.dll, N/A, 10/20/2011)

                RULE LS-32_PMP-1
                IF PUMP LS-32_PMP-1 STATUS = ON
                AND PUMP LS-32_PMP-1 STATUS = ON
                THEN PUMP LS-32_PMP-1 SETTING = 0.100000
                PRIORITY 1.00000

                RULE LS-32_PMP-1A
                IF NODE LS-32 DEPTH > 6.250000
                AND PUMP LS-32_PMP-1 STATUS = ON
                THEN PUMP LS-32_PMP-1 SETTING = 0.750000
                PRIORITY 1.0000

Fix dialog boxes display issues for Win7. (HsMapSrv10.dll, HsCIPSrv10.dll, and HsCIPSrv10.dll, N/A, 10/21/2011)

Improve Scoring Speed for Pipe Condition Scores. (HsCIPSrv.dll, N/A, 12/5/2011)

InfoSWMM v11 Update 4:

Changes & Improvements

DB Editor: Newly Added Information Field won’t appear until the table is re-opened.  It is now fixed. (HsUtilPkg.dll and HsDBBPkg.dll, N/A, 10/5/2011)
Attribute Browser:  Edit Junction Tables All, Domain and Selection were not loading – it is now fixed. (HsHxfSvr.dll and HsDBBPkg.dll, N/A, 10/2/2011)
Fixed a Windows 7 display issue of Preferences dialog.

Attribute Editor: Prevented the dialog switching to the first tab when users sort a data column.   This is now fixed. (HsMapSrv9.dll and HsMapSrv10.dll, N/A,10/2/2011)
                Edit Selection Attributes
                Edit Domain Attributes
                Group Editing on Selection
                Group Editing on Domain

Subcatchment Manager:  Improved the Exception Handling for Creating Subcatchments. (HsSubcatchSrv10.dll , N/A, 10/11/2011)

InfoSWMM v11 Update 3:

New = A very important feature in InfoSWMM and H2OMAP SWMM is the ability to have Network Scenario’s.   Each Network Scenario is either a Base Scenario or a Child Scenario of the Base Scenario or other Child Scenario’s.    The Child Scenario’s may have different Data Set’s associated with them but previously in InfoSWMM and H2OMAP SWMM you could only use the DB Editor with the Data Sets in the Active Scenario.  
You can now use the DB Editor to edit ANY Data Set from any Scenario by using the new Data Set Selection Command at the bottom of the DB Open Table Dialog or by clicking on the ellipsis at the bottom of the dialog. (HsDBBPkg.dll, N/A, 8/26/2011)
An Internal Engine Feature in SWMM 5 and of course in H2oMAP SWMM and InfoSWMM is the automatic raising of the node rim elevation when any connecting pipe crown, weir or orifice is above the existing rim elevation.   Many users of our software use this feature to eliminate the need for entering node maximum depths.  The input HGL profile for would show the zero maximum depth of the node – this is now fixed and the program will plot the highest connecting link crown as the node rim elevation. (HsUI3Pkg.dll and HsOutPkg.dll, N/A, 8/26/2011)
HGL Visual Representation of Weirs, Orifices and Outlets in Input and Output HGL Plots
- Weir, Orifice and Outlets Inverts and Crest Elevation are now shown flat to correspond to the SWMM 5 internal Engine Convention
Link[j].offset2 = Link[j].offset1;. (HsUI3Pkg.dll and HsOutPkg.dll, N/A, 8/26/2011)
The infiltration or evaporation storage node or pond in InfoSWMM may be simulated using Green Ampt Infiltration and Pan Evaporation using options in the Attribute Browser. (HsEngPkg.dll and HsEngPkg64.dll, N/A, 8/31/2011)
                The fixes are:
                1.            The System Evaporation is now in units of inches/day or millimeters/day
                2.            Extra Decimal places were added to the Storage Summary Table

Fix buffer unit conversion so that the proper judgment about the closeness of two pipe defects so that the program may consider merging them. (HsCIPSrv10.dll , N/A, 9/12/2011)
Fix cost lookup with Max. Depth and Min Depth. (HsCIPSrv10.dll , N/A, 9/19/2011)

Trying to color code 2D results might crash the program after mesh data was manually deleted.  Now it has been fixed. (HsSDServices.dll , N/A, 9/14/2011)
DB Editor: Allow the user to edit data table of any desired DATA SET. (HsDBBPkg.dll , N/A, 8/22/2011)

InfoSWMM v11 Update 2:

Exchange\Import EPA SWMM 5 Command:
The Offsets Elevation Flag in a SWMM 5 import data set is now both imported and translated to the Store Absolute Condit Invert Flag in Tools Preferences/Operation in InfoSWMM.  This allows more SWMM 5 compatibility for the InfoSWMM flags using the Import EPA SWMM 5.0.001 to EPA SWMM 5.0.022 Command. (HsDataPkg.dll, N/A, 7/29/2011)
HGL Profile for Small q/Q values:
The output report manager HGL Profile no longer sets the color of the link fill  to white when the value of q/Q and the velocity are both small.  A value of d/D of 1 will still show a blue fill color in the HGL Plot. (HsOutPkg.dll, N/A, 7/29/2011)
Fix of a Hyetograph Name Typo and Reordering. (HsUI4Pkg.dll, N/A, 8/8/2011)
SCS Hydrology CN Printout Clarification: CN in the Output Text File and Output Report Manager. (HsEngPkg.dll and HsEngPkg64.dll, N/A, 8/4/2011)
Trace Network: Insufficient memory allocation for model with long IDs caused the program to crash in Arc GIS.  It is now fixed. (HsUI2Pkg.dll, N/A, 8/4/2011)
Just a reminder as well for Joe – all of Chun-Hou’s recent changes for SCS Hydrology are NOT in the most recent install.  8/11/2011 hsnetviewsrv10.dll
Project Init & Save: support the new ESRI File Geodatabase project. (HeUtilPkg.dll, N/A, 8/18/2011)
Add Risk Tile to report and summary. (HsCIPSrv.dll, N/A, 8/19/2011)

InfoSWMM v11 Update 1:

Output Relate: Fixed Output Relate generation problem for the Junction Summary report. (HsOutPkg.dll, N/A, 6/23/2011)
Increased Mix Graph Options for Outfall Data and System Data. (HsUI2Pkg.dll and HsEngPkg.dll, N/A, 6/6/2011)
Name change for Innovyze-SWMM LID Report File
Importing EPA SWMM file was using an incorrect file selection dialog.  Now it has been fixed.
An update to the DWF Pattern Calculation at Hour 24 when using Variable Time Step.  The pattern is now set at the pattern at hour 23 based on pattern hours from 0 to 23. (HsEngPkg.dll, N/A,

Previously, the Variable Time Step would have an undefined pattern value at hour 24 when the variable time step option was used but fixed time step was properly set to the pattern at hour 23.
Missing file (HnFileMonitor.dll, N/A, 6/7/2011)
Enhanced Low Impact Development (LID) Water Quality Graphics and Report. (HsStatPkg.dll,HsOutPkg.dll HsEngPkg.dll, HsEngPkg64.dll, N/A, 6/7/2011)

Fix the Low Impact Development LID (HsUI4Pkg.dll, N/A, 7/21/2011)  M
Underdrain Height Offset Dialog Unit.
The Underdrain Process Layer consists of:
                1.            Drain Coefficient (inches/hour or millimeters/hour)
                2.            The Void Ratio as a Fraction (0 to 1),
                3.            Drain Exponent
                4.            Drain Offset Height (inches or millimeters)

Changed the name of the Checkbox for Saving Output in the Low Impact Development (LID) Usage Editor for Subcatchments.  The Checkbox if checked saves the detailed LID Control Pathways for each

Control in a Subcatchment (HsUI4Pkg.dll, N/A, 7/20/2011)  M

Output Report Manager: A Change to the Output Report Manager to better handle 1 second time steps in the Report Table Section.  This was added to better see the output for Pumps and Force Mains when the Pumps turn on for only a few seconds.  It also allows the user to see the output data and graph a subset of a  long simulation run.  For example, if the user saves at a one second time step for a week this will allow him or her to see all 604800 data points and graph or perform statistics on 5 second  intervals if needed.  It was needed for those simulations in which the Maximum and Report Time Steps are the Same and the time step is small.  If you do save a million or more data points it would behoove you to use the Domain only as the Output Scope in the Run Manager to cut down on graphing time and the Out Folder Size. (HsOutPkg.dll, HsEngPkg.dll, N/A, 7/15/2011)  M

Browser Simulation Report: Added the Outfall Loading Summary to the Browser Simulation Report to be compatible with the SWMM 5.0.022 Status Report; this information has been and is also available as a Tabular Report in the Output Report Manager
The change is for both the 32 and 64 bit Engines as well as the Output Report Manager. (HsEngPkg64.dll, N/A, 7/15/2011)  M

Put in the LID Help ID and Help Topics connected to the Help ID. (HsUI4Pkg.dll, N/A, 7/26/2011) 

Increased Mix Graph Options for Outfall Data and System Data. (HsUI2Pkg.dll and HsEngPkg.dll, N/A, 6/6/2011)
Name change for Innovyze-SWMM LID Report File
Change MWH Soft to Innovyze in Preferences/Operation Settings tab. (HsMapSrv.dll and HsMapSrv10.dll, N/A, 6/2/2011)
Importing EPA SWMM file was using an incorrect file selection dialog.  Now it has been fixed.
An update to the DWF Pattern Calculation at Hour 24 when using Variable Time Step.  The pattern is now set at the pattern at hour 23 based on pattern hours from 0 to 23. (HsEngPkg.dll, N/A,

Previously, the Variable Time Step would have an undefined pattern value at hour 24 when the variable time step option was used but fixed time step was properly set to the pattern at hour 23.
Missing file (HnFileMonitor.dll, N/A, 6/7/2011)

Subject:  How is the Orifice Setting Used in SWMM 5 RTC Rules?

The Real Time Control Rule for Orifice Setting can be a function of a Setting constant, Setting from a Curve, Setting from a PID controller and a Setting from a Time Series (Figure 1).    The Setting affects the Full Depth of the Orifice at each time step.  The setting which ranges from 0 to 1 can either completely close or open theorifice (Figure 2).   You will have to use the equivalent in ICM or else the settings derived from the SWMM 5 time series need to be multiplied by the orifice depth to have the same effect in ICM that it had in SWMM 5.

How to Simulate Pipe Blockage in InfoSewer Emoji version

Subject:  How to Simulate Pipe Blockage in InfoSewer

For making one or more of your pumps inactive you just need to use the Facility Manager and make the pumps inactive (the grey lines in Figure 2).   The other method of making the gravity mains have a really small diameter will not work as the flow is pushed through anyway and the value of q/Q full is very high.   One way to do what you want to do is to use a Flow Split and make the flow in the blocked link very small as a fraction of the incoming flow.   You will need to add a new link and out fall to handle the excess flow from the pipe blockage (Figure 1). 

InfoSWMM Version 12 Revs Up Modeling Performance With HEC-22 and 64-Bit Support

InfoSWMM Version 12 Revs Up Modeling Performance With HEC-22 and 64-Bit Support
Latest Software Release Supports Faster Time to Design and Lower Analysis Costs
Broomfield, Colorado USA, July 25, 2012 — In its ongoing quest to equip the wastewater industry with the world’s most comprehensive and innovative smart network modeling and management solutions, Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced the worldwide availability of the V12 Generation of its industry-leading InfoSWMM for ArcGIS (Esri, Redlands, CA). InfoSWMM V12 enables engineers to work more efficiently and reliably with very large and complex network models, thanks to improvements in such areas as HEC-22 inlet support, built-in 64-bit simulation, enhanced water quality modeling, and batch run scenario management that will positively impact modeling teams each and every day.
The only urban drainage modeling solution certified by the National Association of GIS-centric Software, the full-featured InfoSWMM analysis and design program delivers the highest rate of return in the industry. All operations of a typical sewer system — from analysis and design to management functions such as water quality assessment, pollution prediction, sediment transport and deposition, urban flooding, real-time control, and record keeping — are addressed in a single, fully integrated geoengineering environment. The program’s powerful hydraulic and water quality computational engine is based on the current SWMM 5 version, which is endorsed by the USEPA and certified by FEMA. These features and more result in an enhanced modeling experience and greater realism of displayed results — advantages that translate to increased productivity, reduced costs, higher accuracy, better efficiency, and improved designs.
InfoSWMM also serves as a robust base platform for advanced modeling, operational, capital planning, and analytics-driven asset management extensions. Some of these critical applications include InfoSWMM 2D (two-dimensional surface flood modeling), CapPlan (risk-based capital planning and asset performance modeling),InfoMaster (GIS-centric asset management), and RDII Analyst (rainfall-dependent inflow and infiltration planning and analysis).
The release of InfoSWMM V12 extends previous generations’ capabilities with significant modeling enhancements and groundbreaking innovations in geoengineering productivity and efficiency. These improvements greatly simplify, accelerate, and integrate urban drainage network engineering, helping wastewater engineers develop better designs and operational improvements faster. Key new built-in modeling and computational tools include:

  • ability to explicitly model five HEC-22 inlet types connecting overland and underground systems (continuous grate inlet, continuous curb-opening inlet, sag grate inlet, sag curb-opening inlet and sag combination inlet),
  • complete 64-bit functionality resulting in faster simulation runs,
  • enhanced hydrogen sulfide and corrosion modeling,
  • flexibility in run time scheduling, 
  • direct control of the number of dynamic solution threads or cores for parallel processing, and
  • ability to run multiple scenarios in batch mode at one time or to schedule the model runs at future times.

“Our priorities have always been to advance the frontiers of smart network modeling technology and support our customers’ successes by helping them be more productive and competitive,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President and Chief Operating Officer of Innovyze. “This major InfoSWMMrelease delivers on our promise to equip our customers with the ultimate ArcGIS-centric decision support tool for sewer collection and urban drainage systems. Like its predecessors, InfoSWMM V12 sets a new standard for quality and high-performance network modeling and management with unrivaled power, cutting-edge capabilities, rich functionality, and ease of use. From top to bottom, this release is designed for record modeling performance that enables users to increase their productivity and quality while achieving their engineering and business goals.”
