Manhole Elevations in InfoSWMM and SWMM 5
Subject: Manhole Elevations in InfoSWMM and SWMM 5
Starting from the bottom of the manhole you have these regions of computational interest: 1.   Manhole Invert to the lowest link invert – the node continuity equation is used with the area of the manhole being the default surface area of a manhole, 2.   Lowest Link Invert to the Highest Link Crown Elevation – the node continuity equation is used with surface of the node being normally half of the surface area of the incoming and outgoing links, 3.   Highest Manhole Pipe Crown Elevation to Manhole Rim Elevation – the node surcharge algorithm in which the surface area of the manhole is not used and the surcharge depth is iterated until the inflow and the outflows of the node are in balance, 4.   The region above the Manhole Rim Elevation which can use one of four options to calculate the depth and/or flow out of or into the manhole: 1.   No Surcharge Depth is entered and No Ponding area is used – the e…

How to Import the SWMM 5 Report File as a Layer in infoSWMM
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 an example Excel file to illustrate the linkage. The steps are: Step 1:  Copy the whole row  from Conduit Summary from the InfoSWMM Browser   Step 2:  Add the two columns length and  slope from the Link Summary Table and the InfoSWMM Browser   Step 3:  You need a few calculations based on the table values from SWMM 5 to estimate the CFL  time steps in the .   Step 4:   Add the Excel Spreadsheet as a layer in InfoSWMM – the Named Range should be added to insure valid numbers and not Nulls after the join   Step 5:  You can now plot the CFL Time Step for the Links using the Layer Properties command in Arc Map  Step 1:  Copy the whole row  from Conduit Summary Step 2:  Add the two columns length…

How to Model Water Quality Time Series in SWMM5

Image
You can model water quality as a SWMM 5 inflow time series using the following steps:
1. Model Water Quality (TSS  for Example)
2. Add the needed inflow Time Series at a Node
3. Include both a Flow
4. and a TSS Time Series 
5. The TSS time Series is Concentration over time
The file at the bottom is an example of the TSS time series
