Using RDII or RTK or I&I Hydrographs in #INFOSEWER, FY2023


Using RDII or RTK or I&I Hydrographs in #INFOSEWER

Using RDII or RTK or I&I Hydrographs in #INFOSEWER – InfoSewer from Innovyze also has the features to model Infiltration/Inflow from Rainfall Events into a Sanitary or Combined Sewershed.  There are three parameters, R, T and K, a Sewershed Area and a fraction division that divides up the overall R to the three individual R’s

1UH has an overall R (percent of Rainfall that turns into Rainfall Dependent Infiltration Inflow)

a.      R1 = Percent R1 * R / 100

b.      R2 = Percent R2 * R / 100

c.      R3 =  R – R1 – R2

Figure 1 shows the Rainfall for InfoSewer

Figure 2 shows the result of using 100 Percent R1, R2 or R3 at a node

Figure 1 - Rainfall for RTK in InfoSewer

Figure 2 - Resultant UH for Nodes with only R1, R2 or R3.
