PROBABILITY DISTRIBUTION EVALUATIONOF A FLOOD DISCHARGE MEASUREMENT
Atsushi MINAMI㧘Minoru KURIKI
Traditionally the output of a discharge measurement has been expressed in a single value. When thefloat method is used, multiple float observations are made to compute the volume per unit time at whichwater flows through a cross-section. Corresponding the measurement conditions of each float or errors
involved in the measurement, the measured velocity of these floats unavoidably includes variation. To
reflect the variation into the result of a discharge measurement, an attempt was made to apply the DIEX
method to express the result as a value with probability distribution. Using the concept, a numericalexperiment based on actual discharge measurements was conducted to evaluate the variation of
extrapolated range of rating curves.
