InfoSewer - Minimum Travel Distance Note:    The minimum travel distance in an  InfoSewer  or H2OMap Sewer model can be related to the mean link length in the Pipe DB Table.  Here is a table of the Mass balance check for one network versus the minimum travel distance in feet for the default values of network accuracy, minimum time length and maximum number of segments at a report time step of 1 hour.   As you can see making the Minimum Travel equal to the mode of the length histogram yields the best results even for the default model parameters.   Minimum Travel Distance Mass Balance Check: Label 1 10.50 (%) 5 3.25 (%) 10 6.25 (%) 20 17.34 (%) 25 7.05 (%) 30 1.38 (%) 40 1.07 (%) 50 1.07 (%) 55 1.05 (%) 58 3.87 (%) 60 3.34 (%) 75 0.55 (%) 80 3.09 (%) 90 11.60 (%) 100 17.20 (%) 200 17.34 (%) 1000 17.34 (%) Tags   A Basic InfoSewer Wet Well/ Pump and Force Main System   InfoSewer - Minimum Travel Distance
