SpletThe Areal Reduction Factor (ARF) [eta] is a key parameter in the design for hydrologic extremes. For a basin of area A, [eta] (A, D, 7) is the ratio between the area-average … Spletverting point depths to a mean areal depth is to multiply the average of the point depths for a given duration, fre-quency and area by a depth-area correction, or an areal reduction factor (ARF). Perhaps the most common source of ARF for the U.S. is Technical Paper 29 (TP-29) (U.S. Weather Bureau, 1957). TP-29 defines ARF as the ratio of the

SpletThe depth-area reduction factor is used to account for the observation from empirical data that average precipitation intensity decreases as the area of a storm increases. Thus the average precipitation intensity of a 200 km 2 storm is generally much less than the intensity of a 10 km 2 storm. Proper determination of the flow at a given ... Splet13. jul. 2005 · [1] The areal reduction factor (ARF) ? is a key quantity in the design against hydrologic extremes.
