Subject: Surcharged Node and the Link Connection in SWMM 5
A surcharged node in SWMM 5 uses this point iteration equation (Figure 1):
dY/dt = dQ / The sum of the Connecting Link values of dQ/dH
where Y is the depth in the node, dt is the time step, … Read the rest
Subject: How to Divide the Inflow at a Node in InfoSWMM
In SWMM 5 only the Kinematic Wave solution allows a flow divider at a node to divide the Inflow to node to two downstream links, but you can use the Inflow/Outflow Outlet type in InfoSWMM to divide the … Read the rest

Subject: Use the SWMM 5 Scatter Graph to show the Pump Curve used during the Simulation
You can use a scatter graph to show the relationship between the pump during the simulation and the Storage Depth. If the pump is on the curve based on the pump summary table then
Subject: How to Import the SWMM 5 Report File as a Layer in infoSWMM
The idea of this blog of note is to show how one may extract information from the SWMM 5 or InfoSWMM RPT file and import the Excel File as a feature in InfoSWMM. This blog has
Subject: How to Approximate a Timer in the RTC Rules of SWMM 5
SWMM 5 does not have a explicit timer in its Real Time Control (RTC) rules but you can approximate it by using a Control Curve as in the attached example model. The Control Curve will … Read the rest
Subject: RDII or Tri Triangular Unit Hydrograph in InfoSewer
The RDII method in InfoSewer is similar to the RDII or RTK method in InfoSWMM with some differences. The RTK data for triangles 1, 2 and 3 are defined in the Unit Hydrograph but instead of individual R values, the overall … Read the rest
Note: The Colorado Urban Hydrograph Procedure (CHUP) 2010 version generates a SWMM 5 Inflows Files containing a time series of flow inflows for 1 to many nodes (Figure 4 and Figure 5). The created Inflows file (Figure 2) can be imported intao InfoSWMM and H2MAP SWMM without any alteration by … Read the rest
Note: How to Use Bing Maps in InfoSWMM as a Basemap
A great feature of Arc GIS 10 is the ability to use background maps from Bing for your model. A few steps are necessary to set up the coordinates, import the basemap, clip the basemap and set the new … Read the rest
