InfoSewer Maximum Number of Segments Sensitivity

InfoSewer Maximum Number of Segments Sensitivity

 

The three Run manager parameters, Maximum Number of Segments, Minimum Travel Distance and the Minimum Travel Distance in InfoSewer and H2OMAP Sewer affect the shape and flow attenuation of the flow in a link.  The effect of altering the Maximum Number of Segments is to reduce the peak flow and spread out the flow as the number of segments increases(Figure 1).

InfoSewer Flow Attenuation Sensitivity

InfoSewer Flow Attenuation Sensitivity 

The three Run manager parameters, Maximum Number of Segments, Minimum Travel Distance and the Minimum Travel Distance in InfoSewer and H2OMAP Sewer affect the shape and flow attenuation of the flow in a link.  The effect of using the flow attenuation is to reduce the peak flow and spread out the flow compared to the No Flag option (Figure 1).

Global Dry Weather Flow Reduction in InfoSWMM and H2OMAP SWMM

Global Dry Weather Flow Reduction in InfoSWMM and H2OMAP SWMM

 A cool tip to reduce the overall dry weather flow in InfoSWMM and H2OMAP SWMM without changing the mean dry weather flow is to do the following:

 1.       Make a Reduction or Increase Flow Pattern in the Operations tab of the Attribute Browser (2),

2.      For example, if we want to have 85 percent of the flow use a value of 0.85

3.      In the Node DWF DB Table (2) use the pattern just created (3)

4.      All of the flows in the DWF table and during your simulation will be reduced by 15 percent.
