Subject:  Steps in Using RDII Analyst for InfoSWMM, ICM and InfoSewer  

  Step 1: Create a Base UH  in the Operation Tab of the Attribute Browser using RDII Analyst (Figure 1)

Step 2: Assign a UH to at Least 1 Node Using the Inflow Icon    

Step 3: Open Up RDII Analyst and Click on New to Create a RDII Session    

Step 4: Define the Flow and Rainfall File     

Step 5: Review the Imported Flow Time Series Step 6: Review the Imported Rainfall  Time Series          

Step 7: Units and RDII Analyst Dates are Controlled by the Simulation Manager   

Step 8: Extract DWF from the Flow Time Series    

Step 9: Assign a UH to at Least 1 Node Using the Inflow Icon

Innovyze Expands United States Regional User Group Series

 

Innovyze Expands United States Regional User Group Series 

New Smart Water Innovation Events in Colorado and Florida Bring Together Local Innovyze User Community

 

Broomfield, Colorado USA, July 3, 2012 — Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced additional dates and locations for Regional User Group Series events. The Rocky Mountain User Group will be held on August 8, 2012, in Arvada, Colorado. Two events are scheduled for the South Florida User Group: September 19, 2012, in Tampa and September 20, 2012, in Lake Worth. These events follow successful user group meetings in Georgia and Texas, a Malaysian seminar series, and Innovyze international user conferences — all clear indications of the company’s unwavering commitment to building the largest global community of engineers and utility professionals charged with safeguarding and improving the world’s water.

“Innovyze is focused on delivering industry-leading customer service and superior smart water network innovations,” said Innovyze President and COO Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE. “Because many of our utility customers in the United States find it difficult to travel long distances for industry conferences and events, we are bringing our engineering-GIS experts to them. In addition to providing a platform for updating everyone on industry best practices and showcasing the latest smart water software tools, these events offer ample opportunities for water professionals to learn from each other and share their strategies and success stories.”

Attendees at the events can expect first-hand reports from peers on how they are utilizing Innovyze software for optimizing and sustaining their drinking water, sanitary and combined sewer, and stormwater systems. Innovyze engineers will also be available to provide technical updates, new product demonstrations, one-on-one consultations, as well as a view of what’s on schedule for Innovyze—and its users—this year. New products to be featured by Innovyze include IWLive for real-time network operational modeling and InfoMaster Sewer for comprehensive asset management.

In addition to the announced events, other regional user groups in the United States are planned for later in 2012. Innovyze customers interested in hosting an event should contact their local Client Service Manager for more information.

Registration
Events are open to new, experienced, and potential users of Innovyze software. To register or to view the current rundown of 2012 events, visit http://www.innovyze.com/news/events.

FEMA, SWMM 5, 2D and LID in InfoSWMM

This circular time line graph shows there has been 11 versions of InfoSWMM with Low Impact Development (LID) modeling features and 2D mesh simulation added for InfoSWMM v10.  The LID modeling features were added to EPA SWMM 5.0.019.  EPA SWMM 5 has been accepted by FEMA since SWMM 5.0.05 and InfoSWMM Models exported to EPA SWMM 5 have been accepted by FEMA since InfoSWMM v4. 

 

How does the Infiltration Maximum Time to Drain the Upper Soil Zone Work in SWMM 5 Green Ampt?

Subject:  How does the Infiltration Maximum Time to Drain the Upper Soil Zone Work in SWMM 5 Green Ampt? 

 

You can use the monthly soil recovery factor (Figure 1) in SWMM 5 to change how the Infiltration Maximum Time to Drain the Upper Soil Zone (Figure 2) is computed each month during a continuous simulation.  

 

The  depth of the upper soil zone in the internal  SWMM 5 units of feet is calculated at the start of the simulation based on the Green Ampt Soil Saturated Hydraulic Conductivity 

 

Upper Soil Zone Depth = 4  * (Soil Saturated Hydraulic Conductivity * 12 * 3600)^0.5 / 12 

 

And the Upper Zone Moisture Depletion Factor  and Infiltration Maximum Time to Drain the Upper Soil Zone is calculated at each hydrology time step in SWMM 5. 

 

Upper Zone Moisture Depletion Factor  = Upper Soil Zone Depth / 300 * 12 /3600 * Monthly Evaporation Recovery Factor 

 

Infiltration Maximum Time to Drain the Upper Soil Zone = 6 / (100 * Upper Zone Moisture Depletion Factor  )
