 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 Rangeshould 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 and  slope from the Link Summary Table



Step 3:  You need a few calculations based on the table values from SWMM 5 to estimate the CFL  time steps.

The CFL Step      = Length / (Full  Velocity + (Gravity * Full Depth)^0.5)
Full Velocity        = Full Flow / Full  Area

You also need to create a Name A Range for you data so that the data does not show up as Nulls

 Step 4:  Add the Excel Spreadsheet as a layer in InfoSWMM – the Named Range should be added
 
 Step 4:  Join the Excel  Table to the InfoSWMM Conduit Feature Layer
 
 Step 5:  You can now plot the CFL Time Step for the Links using the Layer Properties command in Arc Map
