Innovyze St Venant Solutions for InfoSewer, H20Map Sewer, #InfoSWMM, H2OMap SWMM and #InfoWorks_ICM and #InfoWorks_ICM_SE

This blog contrasts the St Venant Solutions for InfoSewerH20Map Sewer (1), InfoSWMM/H2OMap SWMM and ICM/ICM SE.

1.  Assumptions for the St. Venant Equations

The assumptions behind Lumped and Distributed Models along with the assumptions of the St Venant equations.  InfoSewerH20Map Sewer, InfoSWMM, H2OMap SWMM, SWMM5, ICM and ICM SE are all Distributed models for Unsteady flow.  InfoSWMM and InfoSewerH20Map Sewer have options for direct steady flow.  ICM and InfoSWMM can also use a quasi steady flow solution.   All of these Innovyze models use the Continuity Equation and Momentum equation for routing flows in links.  The numerical solution differs between the three Innovyze main  platforms:

• InfoSewer and H2OMap Sewer
• InfoSWMM,  H2OMap SWMM and SWMM 5
• ICM and ICM SE

Continuity Equation

Various Forms of the Momentum Equation

2.  Muskingum-Cunge for InfoSewerH20Map Sewer

The continuity (mass conservation) equation is:

where

x          =          distance along the pipe (longitudinal direction of sewer)

A          =          flow cross sectional area normal to x

y          =          coordinate direction normal to x on a vertical plane

d          =          depth of flow of the cross section, measured along y direction

Q         =          discharge through A

V          =          cross sectional average velocity along x direction

S0         =          pipe slope, equal to sin θ

θ          =          angle between sewer bottom and horizontal plane

Sf            =          friction slope

g             =          gravitational acceleration

t           =          time

β          =          Boussinesq momentum flux correction coefficient for velocity distribution

5. A common look at the Equations for ICM, ICM  SE. InfoSWMM and H2OMap SWMM

ICM 2D and InfoSWMM 2D Equations

ICM 2D and InfoSWMM share the same computational engine as described on the Innovyze Blog

As the scheme is an explicit solution it does not require iteration to achieve stability within defined tolerances like the ICM 1D scheme or the iterative solution in InfoSWMM.  Instead, for each element, the required timestep is calculated using the Courant-Friedrichs-Lewy condition in order to achieve stability, where the Courant-Friedrichs-Lewy condition is

How to use the Flow Splitter in InfoSewer for Dendritic Networks

Subject: How to use the Flow Splitter in InfoSewer for Dendritic Networks

InfoSewer, which is an extension in Arc Map, does need to have slit split defined where gravity mains merge together to determine the amount of flow in each of the downstream conduits (Figure 1).   The options for the flow splitter in each of the downstream links are:

1. Automatic Allocation

2. Fixed Flow Percentage

3. Variable Flow Percentage and

4. Inflow-Outflow Curve

At an outfall where the invert of the outfall pipe is raised compared to the inverts of the incoming and outgoing pipes a flow split of Variable Flow Percentage or Inflow/Outflow curve may work better (Figure 2). 

Figure 1. Options for Performing a Flow Split in InfoSewer

Figure 2.  The Effect of the flow split can be used to model complex situations in a dendritic model with outfalls.

H2S Modeling in an InfoSWMM Pond

The control of odorous gases and the corrosion of sewers are the two most important problems in operating wastewater collection systems.  H2S is the most commonly known and prevalent odorous gas associated with domestic wastewater collection and treatment systems.  InfoSewer. InfoSWMM, H2OMap SWMM or H2OMAP Sewer suite gives wastewater engineers a powerful Operations and Maintenance (O&M) tool to readily model and analyze entire sewer collection systems for sulfide generation and corrosion potential under varying conditions anticipated throughout the life of their systems. H2S  predicts sulfide buildup in sewer collection systems for gravity sewers, force mains, and wet wells using the Pomeroy-Parkhurst equations. This unique and powerful tool enables wastewater utilities to pinpoint odor and corrosion problems, develop effective monitoring programs, alert plant operators and sewer maintenance workers to potential danger and the need to observe safety practices, and evaluate and implement effective control system such as aeration, chlorination, and mechanical cleaning.

Modeling of hydrogen sulfide using H2S Detector requires minimal input data from the user. The required data include:

 average daily temperature for the region (in degrees C).

 reaction rate coefficient (per day) which was described above in relation to BOD modeling.

 pH of the wastewater. The normal pH range of municipal wastewater is 6.0 to 8.0.

 effective sulfide flux coefficient  for sulfide generation by the slime layer in gravity sewers (meter/hour). For conservative analysis (i.e., observed sulfide buildup generally less than predicted), the suggested values of this parameter is 0.00032.

 a dimensionless coefficient to account for sulfide losses by oxidation and escape to atmosphere. For conservative analysis (i.e., observed sulfide buildup generally less than predicted), the suggested values of this parameter is 0.64. For moderately conservative analysis a value of 0.96 is suggested.

 logarithmic ionization constant for hydrogen sulfide (unit less), a function of temperature and specific electrical conductance of the waste water. Its value generally varies from 6.67 (at a temperature of 40oC and specific electrical conductance of 50, 000 micromhos/cm) to 7.74 (at a temperature of 10oC and specific electrical conductance of 0 micromhos/cm).

 percent of total sulfides that occur in the soluble (dissolved) form for the wastewater, most frequently known to vary from 70 to 90 percent.

The default values used by the model for these inputs are shown in the following dialog box. In addition to the listed data, the user has to supply initial concentration of total sulfides and ultimate BOD of  the wastewater. These two variables could be assigned using the quality tab available at the top of the attribute browser, for one source node at a time, or using the " Group Edit on Domain" feature that enables simultaneous assignment of the two variables for all source nodes in the domain.

2014 - That was fun - an update of an announcement from the past.  The original is on our website. I changed my name from Bob to Robert, the company name from MWHSoft to Innovyze and list my my actual job or jobs I have been doing at @Innovyze from 2008.  I left the title alone - sometimes it is best to have a goal in life and trying to achieve the title of the announcement is something I would like to approach in my remaining Innovyze years.  I probably will not reach it but I appreciate the mastery of the Paul Boulos announcements - he writes the most creative and wonderful press releases. You should subscribe to them from www.innovyze.com if you want to read about the future of water, sewer and stormwater.  A final mention of Alight Tsai who manages http://www.innovyze.com/ and is always helpful with great images for our software and help files.  I would be remiss if I did not mention our great R/D product development teams in Monrovia and Wallingford. I am proud to be a small part of the Monrovia team.  Other history mentions about SWMM3/4/5 in my past can be found here http://www.swmm5.net/2012/05/my-history-with-various-versions-of.html

Another update for May 2015 - we are making great strides in social media led by our Director of Marketing Rajan Ray who can be found at @InnovyzeRaj and in general at @Innovyze. You can see all of our tweets by searching for Innovyze on Twitter
