Description

Measurements were taken in a rectangular flume in a hydraulics laboratory to determine surface velocity coefficients for the float method, used in open-channel flow measurement, and to obtain detailed cross-sectional velocity profiles under steady-state, uniform flow conditions. Various longitudinal bed slopes were used, each with a series of different flow rates. Measured values were compared to published surface velocity coefficients, and the cross-sectional velocity profiles were used to help calibrate a three-dimensional mathematical model of open channel flow, currently being used in the study of surface velocity coefficients for the calibration of the float method.
