InfoSewer Flow Attenuation Sensitivity
The three Run manager parameters, Maximum Number of Segments, Minimum Travel Distance and the Minimum Travel Time 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).

InfoSewer Minimum Travel Time Sensitivity
The three Run manager parameters, Maximum Number of Segments, Minimum Travel Distance and the Minimum Travel Time in InfoSewer and H2OMAP Sewer affect the shape and flow attenuation of the flow in a link. The effect of decreasing the Minimum Travel Time is to reduce the peak flow and spread out the flow as the number of segments increases(Figure 1). The larger the Minimum Travel Time, which has the effect of decreasing the number of segments in a link up the limit of the parameter Maximum Number of segments, the smaller the peak and the more attenuation of the flow in InfoSewer.
There is three ways to control attenuation in InfoSewer: (1) use the flow attenuation option, (2) increase the Maximum Number of Segments per link and (3) decrease the Minimum travel distance. You can also use all three parameters to make more segments per link for long links and only a few segments for short links.

InfoSewer Maximum Number of Segments Sensitivity
The three Run manager parameters, Maximum Number of Segments, Minimum Travel Distance and the Minimum Travel Time 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).
