The Storm Water Management Model (SWMM) and InfoWorks networks share a common user experience (UX); similar data structures, output files, UX tools, and Ruby and SQL scripting mean that both systems have been designed with a focus on user-friendliness and interoperability. This facilitates the learning curve and overall productivity for … Read the rest
Maintain the Force Mains at full capacity with a diameter-depth ratio (d/D) of 1 when the pumps turn On
A challenging issue in modeling and managing sewer force mains using the SWMM 5 system. The crux of the problem is maintaining the force main at full capacity with a diameter-depth ratio (d/D) of 1 when the pumps turn on.
The SWMM 5 system uses one flow point in the … Read the rest
How to Use Tracer Water Quality for RDII, DWF, and Runoff in an InfoWorks ICM Network – Use SWMM5 Washoff
The integration of ICM SWMM into the ICM platform has brought with it the inclusion of the SWMM5 Buildup Washoff feature. This allows users to analyze the impact of tracer concentrations on a 1D network, specifically in determining the percentage contribution of real-time kinematic (RTK) urban hydrology or runoff to … Read the rest
You can find the install for the Design Storm Wizard on this openswmm thread https://www.openswmm.org/Topic/32275/dstorm-a-design-storm-wizard. A very adaptable rainfall tool for SWMM5, that generates rainfall distributions based on user IDF, NOAA Atlas 14 IDF for Chicago, nested or composite choices. If IDF is not used, the user can save … Read the rest
Conversion of InfoSWMM models to both ICM SWMM and ICM InfoWorks Networks.
I will show you how in a short 3-minute video with captions. It is very straightforward and well-designed and allows you to model SWMM5 Networks using SQL, Grids, Reports, Graphs, Themes, Modeling Objects, Data Flags, and Ruby Scripts.… Read the rest
Junction Dry Weather Flow (DWF)
The Junction Dry Weather Flow (DWF) data table stores information regarding the dry weather load (e.g., sanitary loads) entering the collection system at the junction node. Refer to the section on the inflow editor for more information on these input data. The following table shows … Read the rest
