A rise in Pipe Inverts Across a SWMM 5 Node, What Node and Link Invert Elevations Does SWMM 5 Use?

A rise in Pipe Inverts Across a SWMM 5 Node

Subject:  This is how SWMM 5 handles  jumps in pipe invert across a node. 

 The water surface in the node determines the flow in the link, as the depth increases due to upstream inflow eventually the downstream link will start flowing.

What Node and Link Invert Elevations Does SWMM 5 Use?

Note:  What Node and  Link Invert Elevations Does SWMM 5 Use?

SWMM 5 uses the following Node information from the user:

·         Node Invert Elevation,

·         The Node Rim Elevation which is the Node Invert Elevation + the Maximum node depth

·         The Ponded Area when the Ponded  Area option is used

·         The Surcharge Depth above the Node Rim Elevation

SWMM 5 uses the following link information from the user:

·         The Link Upstream Offset Depth or Offset Elevation and

·         The Link Downstream Offset Depth or Offset Elevation

·         The Link Maximum Depth or Diameter

SWMM 5 calculates the following information internally:

·         The Pipe Crown Elevation at the upstream and downstream link nodes.  The Pipe Crown is the Pipe Diameter + Link Offsets

·         The Node Highest Pipe Crown Elevation,

·         The Surcharge Depth above the Rim Elevation if the Node has a Surcharge Pressure Depth at the Node during the simulation,

o   If the Surcharge Depth is 0 then the program will either lose the flooded water or store the flooded water during the simulation

·         The Flooded Depth above the  Rim Elevation if the Node uses the Ponded Area Option

o   You have to enter a Ponded Area for the node AND use the Global Allow Ponding Option

SWMM 5 Rules for Pipes

·         The Pipe Invert Cannot be below either upstream or downstream node invert – the program will print a warning in the rpt file and set the offset to 0 internally,

·         The Pipe Crown Cannot be above the Rim Elevation of the Node – the program will raise the Rim Elevation when this happens and print a warning in the rpt file.

The use of Offset Depth or Offset Elevation for the Link Offsets is based on the user choice at the bottom of the SWMM 5 GUI Map.

Or in the Tools/Preference/Operation dialog of InfoSWMM/H20MAP SWMM

Showing Multiple Link Attributes in InfoSewer

This blog shows how to display multiple link parameters.

The 1st method would be to use Arc Map Layer properties and label multiple parameters for each gravity main or force main.  The image below shows and example and here is the code inside of Arc Map to do this

Function FindLabel ( [DIAMETER], [Pipe.SHAPE_Length], [COEFF] )
  FindLabel = [DIAMETER] & " m / "  & " " & [Pipe.SHAPE_Length]  &  " m / n "   & [COEFF] 
End Function

Arc Map Label Annotation

Or 

Function FindLabel ( [DIAMETER], [Pipe.SHAPE_Length], [COEFF] )
  FindLabel = " D= " & [DIAMETER] & " m / L="  & " " & [Pipe.SHAPE_Length]  &  " m / n "   & [COEFF] 
End Function
 

Label Properties in Arc Map or Arc GIS

The 2nd method is to use Annotation and Map Display in InfoSewer

If you want to show both pipe diameter and slope on the map of InfoSewer you will have to workaround the limitation of having only one map variable:
1. You can map the diameter using Map Display and then
2. Use the Annotation tool to show the 2nd variable such as Length or slope.
3. Here is an example with different colors for diameter and length

InfoSWMM 2D Version 13 Brings Significant 1D and 2D Simulation Advancements To Power Users

Latest Release Confirms Product as Leading GIS-centric Urban Drainage Modeling and Management Solution

Broomfield, Colorado, USA, November 18, 2014

Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the worldwide availability of the V13 Generation of its industry-leading InfoSWMM 2D for ArcGIS (Esri, Redlands, CA). InfoSWMM 2D delivers new ways to quickly and accurately build and analyze very large and comprehensive two-dimensional (2D) models that reliably simulate complex urban stormwater, sanitary sewers, river flooding and pollutant transport. It allows users to accurately predict the extent and duration of urban and rural flooding for comprehensive stormwater management directly within the powerful ArcGIS environment.

A fully hydrodynamic geospatial stormwater modeling and management software application, InfoSWMM 2D can be used to model the entire land phase of the hydrologic cycle as applied to urban stormwater systems. Built atop ArcGIS and using exceptionally robust and efficient numerical simulation capabilities, the model can perform single-event or long-term (continuous) rainfall/runoff simulations accounting for climate, soil, land use, and topographic conditions of the watershed. In addition to simulating runoff quantity, InfoSWMM 2D can reliably predict runoff quality, including buildup and washoff of pollutants from primarily urban watersheds. It also features very sophisticated Real-Time Control (RTC) schemes for the operational control and management of hydraulic structures.

A hallmark of InfoSWMM 2D is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in open channels, HEC-22 inlets and closed pipe networks with two-dimensional (2D) hydrodynamic simulation of surface runoff, evaporation, infiltration and flooding in the urban environment. The dynamic integration, achieved through an explicit coupling of 1D and 2D flow equations, provides a powerful solution for simultaneously modeling belowground and aboveground elements of watersheds to accurately represent all flow paths and improve understanding of holistic processes. InfoSWMM 2D also directly simulates the rainfall and infiltration on both the watershed and the 2D surface to better simulate 1D flooding, 2D surface flooding, 2D shallow groundwater recharge and complex 1D and 2D surface interactions.

The full 2D free-surface shallow water equations are solved using a highly advanced finite volume method, which is particularly suitable for rapidly varying flood flows such as those moving through steep streets and road junctions and those associated with bank overtopping or breaching. The unparalleled 1D/2D dynamic linking capabilities of InfoSWMM 2D give engineers the unprecedented power to analyze and predict potential flood extents, depth and velocity and accurately model the interaction of surface and underground systems in an integrated 1D/2D environment. The software can be used to simulate point sources, 2D boundaries, multiple 2D mesh and simulation polygons in a sewer or stormwater network. The combined water level and velocity results throughout the flooded areas can be viewed as various comprehensive graphs; tables; or animated, thematic flood maps.

Among its many new enhancements, Version 13 uses a significantly improved 2D simulation engine, the flexible InfoSWMM ArcMap polygon tools, a 1D InfoSWMM engine based on the latest EPA SWMM 5.1, a new 1D and 2D graphics engine and a comprehensive Output Report Manager and Statistical Event Manager for both 1D and 2D output. In addition, the new release allows users to instantly visualize the maximum extent of flooding in vivid 2D and 3D maps.

“We’re deeply committed to providing a geospatial modeling experience that is both intuitive and powerful, and InfoSWMM 2D V13 embodies that commitment,” said Paul F. Boulos, Ph.D., BCEEM, NAE, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “This release delivers major geotechnological and computational enhancements in short release cycles to make sure our customers are always equipped with the ultimate ArcGIS-centric decision support tool for stormwater and urban drainage systems. It greatly extends the core features of InfoSWMM, providing the most powerful and comprehensive ArcGIS-centric tool kit ever for managing the risks of urban and rural flooding. This is a must have for effectively controlling and managing sanitary sewer and combined sewer overflows.”

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:

1. Make a map display of the maximum top width during the simulation, the variable is MXTOP_WIDH and will added to the Arc Map TOC
2. Use the Buffer Command in Arc Map and a field of MXTOP_WIDH
3.  the Buffer Command in Arc Map and the Pipe or Link feature class
4. I have Arc Map Standard so I cannot use Create Polygons from Lines or Advanced Editing which might work for you http://resources.arcgis.com/en/help/main/10.2/index.html#//01m600000015000000
5. There 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, hour);       //(5.0.019 - LR)

    }

    return f * inflow->avgValue;   

Here is the new 2014+ code,  which adjusts the pattern  factor based on the day of the week.

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    p1, p2;                     // pattern index

    double f = 1.0;                    // pattern factor

    p1 = inflow->patterns[MONTHLY_PATTERN];

    if ( p1 >= 0 ) f *= inflow_getPatternFactor(p1, month, day, hour);   // Pattern f value is 1 * The Monthly Factor

    p1 = inflow->patterns[DAILY_PATTERN];

    if ( p1 >= 0 ) f *= inflow_getPatternFactor(p1, month, day, hour);   // Pattern f value is last f * The Daily Factor

    p1 = inflow->patterns[HOURLY_PATTERN];

    p2 = inflow->patterns[WEEKEND_PATTERN];

    if ( p2 >= 0 )

    {

        if ( day == 0 || day == 6 )

            f *= inflow_getPatternFactor(p2, month, day, hour); // Pattern f value is last f * The Hourly Factor for Saturday and Sunday

        else if ( p1 >= 0 )

            f *= inflow_getPatternFactor(p1, month, day, hour); // Pattern f value is last f * The Hourly Factor Monday to Friday

    }

    else if ( p1 >= 0 ) f *= inflow_getPatternFactor(p1, month, day, hour);  // Pattern f value is last f * The Hourly Factor

    return f * inflow->avgValue;

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 http://docwiki.embarcadero.com/RADStudio/XE7/en/FireMonkey_and_TeeChart  I got it work in XE7 but I did have to remove XPPRINTER references from the Delphi code.  

CONTENTS OF SWMM5.1.007_GUI.ZIP
=============================

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).

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 surcharge and open channel weirs that cannot.

6.   The formula used to recover infiltration capacity during

     dry periods for the Modified Horton method was revised.

7.   The initial cumulative infiltration into the upper soil

     zone for Green-Ampt infiltration had been incorrectly

     set to the maximum value instead of zero.

8.   All of the Green-Ampt infiltration functions were

     re-factored to make the code easier to follow.

9.   The calculation of infiltration out of the bottom of a

     Bio-Retention Cell or Permeable Pavement LID unit with a

     zero-depth storage layer was corrected.

10.  Most of the LID simulation routines were modified to

     provide more accurate results under flooded conditions.

11.  Results written to the detailed LID results report now

     always correspond to a full reporting time step.

12.  The name of the variable used to represent the height of

     the receiving channel bottom in a user-defined groundwater

     flow equation was corrected to match the name displayed

     in the GUI's Groundwater Editor dialog (Hcb).

13.  A problem with the program crashing when a climate file

     was used to provide evaporation rates for open channels

     and storage nodes when runoff was not computed (as when

     there were no subcatchments in the project) was fixed.

14.  Flow and pollutant routing mass balance accounting was

     modified to correctly handle negative external inflows.

15.  The procedure for computing the area available for seepage

     out of a storage node that has a tabular storage curve was

     corrected.

16.  Seepage from storage units can now be modeled using Green-

     Ampt infiltration, which makes the seepage rate a function

     of storage level. The constant seepage rate option can

     still be used by setting the G-A initial moisture deficit

     to 0.

17.  The function that finds depth as a function of volume from

     a storage curve was corrected for the case where the depth

     falls within a portion of the curve where area is constant

     with depth (i.e., vertical side walls).

GUI Updates:

1.   The Object Toolbar was restored.

2.   A new page was added to the Climatology Editor to edit

     values for monthly adjustments for temperature, evaporation,

     and rainfall.

3.   A field for the new weir surcharge option was added to the

     Weir Property editor.

4.   A problem with the current project being closed without

     asking if it should be saved first whenever a new style

     theme was selected from the Program Preferences dialog

     has been fixed.

5.   The default seepage rate from an LID storage layer was changed.

6.   The Infiltration Editor was restored for editing Green-Ampt

     parameters for storage unit seepage loss.

7.   The Groundwater Flow Equation Editor was extended to accept

     equations for deep groundwater flow.

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 node
• The 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
