Rawls & Brakensiek soil parameter estimates for #SWMM5 and #INFOSWMM

Image
The original source is http://www.gsshawiki.com/Infiltration:Parameter_Estimates and has been modified to have values in mm instead of cm Infiltration:Parameter EstimatesIt is best to use soil property and Green-Ampt infiltration parameters derived from field and laboratory measurements of infiltration on the study watershed. Even under controlled conditions hydraulic soil property measurements are very difficult. Hysteresis effects and the extremely non-linear behavior of soil water retention make it very difficult to uniquely identify soil infiltration parameters. Hydrologic studies seldom have budgets sufficient to determine the needed parameters in the field. Considerable prior research has been performed to relate soil infiltration parameter values to textural classification. Some highly relevant references are Rawls and Brakensiek (1983) and (1985), and Rawls et al. (1982) and (1983). Table 9 summarizes Rawls and Brakensiek soil parameter estimates as a function of United States …

How to Make an Upstream Interface file for two InfoSWMM Runs

How to Make an Upstream Interface file for two InfoSWMM Runs Subject:  How to Make a SWMM 5 Interface File from InfoSWMM  for  later usage The steps are easy: 1.       Make all Downstream Links from you nodes Inactive by using the Facility Manager 2.       Change the Downstream node to an Outfall 3.      Save the flows to the OUTFLOWS file of InfoSWMM - the outfalls will be saved to the OUTFLOWS file 4.      The Outflow Flows for each New Outfall will be saved to the Text File 5.      Use the Created OUTFLOWS file as the INFLOWS file in the next run if InfoSWMM - you need to change the node back to a regular node and not an outfall node

System Graphs in InfoSWMM and H2OMap SWMMM for SWMM5 Analysis

Image
One of the many key output graphics you can see both graphs and tables in InfoSWMM and H2OMap SWMM are the system processes.  You can define the processes you want to use in the Run Manager along with these hydrology options for both infiltration:
1. Green Ampt
2. Horton
3. Modified Horton 
4. CN 

and Runoff Models
1. EPA Runoff
2. CUHP
3. NRSCS Dimensionless UH
4. NRSCS Triangular UH
5. Delmarva UH
6. Clark UH
7. Snyder UH
8. Espey UH
9. San Diego Modified Rational Method
10.  Modified Rational Method
11. Santa Barbara UH

You can see the process flows in the System Output Graphs and Reports.

H2S Modeling in an InfoSWMM Pond

Image
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 i…

Simulation Task Manager in InfoSWMM and H2OMap SWMM

Several factors can effect the processing time needed to run simulations of sewer networks including computer hardware, simulation timestep, reporting timestep, size of the network, length of simulation, sophistication of the simulation (e.g. controls, 2D) etc. Even though our products utilize the most robust solution engines possible, simulations can take a while to complete. Simulation Task Manager allows you to disconnect the simulation of modeling scenarios from other modeling work so that you can be more productive while simulations are running.

Simulation Task Manager allows you to:
Start, pause and delete scheduled simulations View summary and detailed information about each scheduled simulation Continue to process simulation tasks without the model open that scheduled the simulation Using Simulation Task Manager will greatly enhance your ability to be productive when working with simulations that take a long time to complete. This technical advancement once again shows the d…

The Advanced Tab in InfoSWMM and H2OMap SWMM - how do I control the Size of my Output File?

The Advanced Tab in InfoSWMM and H2OMap SWMM  1/ There are three main ways to save output files for H2OMap SWMM and InfoSWMM 1. All 2.. Domain 3. Selection Set pic.twitter.com/iKADYCCr4F — Robert Dickinson (@InnovyzeRobert) July 8, 2015
2/ Save All saves all information for all elements at each report time step for InfoSWMM and H2OMap SWMM pic.twitter.com/epqE938cy1 — Robert Dickinson (@InnovyzeRobert) July 8, 2015
3/ Save Domain saves only the saved Domain at each report time step for InfoSWMM and H2OMap SWMM pic.twitter.com/fLLjhSxuLv — Robert Dickinson (@InnovyzeRobert) July 8, 2015
4/ Save Selection Set saves only a previous Domain at each report time step for InfoSWMM and H2OMap SWMM pic.twitter.com/mcr9m8cndm — Robert Dickinson (@InnovyzeRobert) July 8, 2015
