Discharge measurements of streams

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 distance to any point in a stream's cross-section is measured from an initial point on the stream bank. Discharge measurements are marked at 2, 5, 10, or 20 feet intervals for cableways and bridges. Distance between …

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. Key words tracer; current meter; river discharge; stage–discharge relationship; suspended sediment; … WebThis stage-discharge relationship is called a rating curve. It’s developed by making frequent manual discrete discharge measurements at stream gaging stations. The rating curve depends on the physical characteristics of the stream channel and floodplain, and will vary over time at almost every station.
