The difference between orifice and notch is size; orifice is smaller than the notch. The quantity of flow measures by orifice is smaller than the notch . Orifices are classified based on size, shape, discharge conditions and shape of the upstream edge.

The U.S. Geological Survey is active in measuring time of travel in streams using dye tracers. This manual describes methods of measuring time of travel of ... WebWe report the results of field and laboratory investigations of stream-aquifer interactions in a watershed along the California coast to assess the impact of groundwater pumping for irrigation on stream flows. The methods used include subsurface sediment sampling using direct-push drilling, laboratory permeability and particle size analyses of sediment, …
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. 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 ...

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 …
Web222Rn was used in the karst drainage basin of the Rio Grande de Manati in Puerto Rico to study groundwater/surface flow relationships. Locations of groundwater influx along two sections of the Rio Grande de Manati were identified.
