2. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   Water metering is the practice of measuring water use. Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system. They are also used to determine flow through a particular portion of the system. In most of the world water meters are calibrated in cubic ...

3. Parshall flume - Wikipedia

7. Aquifer test - Wikipedia

   en.wikipedia.org/wiki/Aquifer_test

   Aquifer testing is a common tool that hydrogeologists use to characterize a system of aquifers, aquitards and flow system boundaries. A slug test is a variation on the typical aquifer test where an instantaneous change (increase or decrease) is made, and the effects are observed in the same well. This is often used in geotechnical engineering ...
