How to Setup RDII in InfoSewer Pro (Storms)
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
2Figure 1 shows the Rainfall for InfoSewer
3Figure 2 shows the result of using 100 Percent R1, R2 or R3 at a node
4T is in hour and T*K is the Time Base of the resulting UH
Step 1. Define the hyetograph or rainfall as a curve
Figure 1 Rainfall for RTK in InfoSewer
Step 2. Define the UH 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 2 Define the RTK values. Note R3 is calculated
