WebThe value 484 in the peak-flow equation (see below) from the NRCS Unit Hydrograph is defined as the peak rate factor (PRF). However, this value is empirical and was estimated in the mid-20th century with watersheds on the Midwest. Using a PRF of 484, 37.5% of the area of the unit hydrograph is under its rising limb. WebThe model uses a dimensionless unit hydrograph, with the drainage area, the depth of the runoff volume, the time‐to‐peak, and the SCS peak rate factor required to dimensionalize …
