Chapter 19: Measurement of Stream Velocity and Discharge

WebMeasurement of cross sectional area and average velocity, although simple in concept, are frequently non-trivial to determine. The units that are typically used to express discharge in streams or rivers include m 3 /s (cubic meters per second), ft 3 /s (cubic feet per second or cfs) and/or acre-feet per day. Webthe preliminary results of a comparison between current meter and artificial tracer measurements are reported. In particular, field tests in a small tributary have been performed, in order to investigate the behaviour of different tracers.
