Abstract: Data collected during a seventeen-year effort to field calibrate a broad-crested, V-notch or triangular weir were analyzed to determine characteristics of the measurement error. The runoff from a 33.6 ha cornfield, located in southwestern Iowa, U. s. A., near Council Bluffs, was gaged using a broad-crested, 2:1, . triangular weir. Laboratory calibration was availabie, but the validity of the laboratory calibration for this field situation was not known. A study was established to field calibrate theweir. A statistical analysis of the data provided some indication of the measurement error associated with the published runoff records. Sources of this variability are discussed.
