1 Methods of Measuring Precipitation Rain gauge Tipping Bucket Wet/Dry Collector Rd Radar Sattelite On the ground point measurments vs remote measurements Effective Depth of Precipitation estimated from on ground point measurements • Average amount of precipitation measured from several stations within a watershed. • The Effective depth of precipitation can be estimated via several means, all using some form of weighted averaging. Arithmetic Mean P N pi mean i N 1 1 P mean = average effective depth of precipitation N = number of precipitation measuring stations P i = the amount of precipitation measured at station I i varies from 1 to N (From: WW 2010 Project University of Il inois, Point Precipitation Measurements, Areal Estimates and Relationships to Hydrologic Modeling, via ABRFC Home Page - ht p:/ info.abrfc.noaa.gov/) •Simplest method. •Satisfactory method if gages are uniformly distributed and if individual variations are not great.
