WebStream discharge (units of volume/time) is dependent upon the product of two somewhat independent measurements: velocity (units of distance/time) and cross-sectional area … Web10. Measurement by Floats . The approximate velocity of flow in a canal or stream and discharge may be determined by the use of floats (British Standards Institution, 1964). Because a number of other methods are usually easier and more accurate to use, this method should be used only when the other methods are impractical or impossible. WebA stream or river monitoring project can also require the observation and measurement of water quality. In these situations, a multi-parameter water quality sonde is recommended. Multi-parameter sondes differ from brand to brand and model to model, but they are unified by a few common traits. As would be expected, multi-parameter sondes usually ... internet data tracking software

Webcomputing stream discharge (Sauer, 2002; Rantz et al., 1982). Stream discharge is typically measured and equipment is inspected at each gauging station every four to eight weeks. The relation between stream stage and stream discharge is evaluated following each discharge measurement at each site, and shifts to the relation are made if … WebBoat-mounted Acoustic Doppler Current Profilers (ADCP) are commonly used to measure the streamwise velocity distribution and discharge in rivers and open channels. Generally, the method used to integrate the measurements is the velocity-area method, which consists of a discrete integration of flow velocity over the whole cross-section. The discrete …

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.
