===Acoustic Doppler velocimetry===
[[Acoustic Doppler velocimetry]] (ADV) is designed to record instantaneous velocity components at a single point with a relatively high frequency. Measurements are performed by measuring the velocity of particles in a remote sampling volume based upon the Doppler shift effect.<ref name="Chanson 2008">{{Cite book |author=Chanson, Hubert |author-link=Hubert Chanson |title=Acoustic Doppler Velocimetry (ADV) in the Field and in Laboratory: Practical Experiences |url=http://espace.library.uq.edu.au/view/UQ:159549 |publisher=in Frédérique Larrarte and Hubert Chanson, Experiences and Challenges in Sewers: Measurements and Hydrodynamics.
