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 relationship between the 15-min flow rate and the full hourly volume is given by the peak hour factor, defined in Part A of this chapter (see below). Whether the design hour was measured, established from the analysis of peaking patterns, or based on modeled demand, the peak-hour factor (PHF) is applied to determine design hour flow rates.
