Water properties

The curvature of light rays by refraction is equal to $\gamma=-n{-1}dn/dz=n{-1}(dn/d\rho)(-d\rho/dz)$. For $-d\rho/\rho dz=1\%$ over a depth of 1 m,the curvature is $\gamma=1.75\: 10{-3} m{-1}$. The equation $z(x)$ of the ray propagating along $x$ is then $z=ax-\gamma x2 /2$.

Conductivity probes

measure conductivity and temperature at the same location, high spatial (1 mm) and temporal (0.1s) resolution.

Ultrasound probes

Capacitive level sensor

Vectrino Acoustic Doppler Velocimeter

This provides pointwise measurement of the three velocity components, with response time about 0.01 s. We have two instruments: One is downlooking, and the second one is side looking, which can be useful near a wall.

See documentation: Datasheet_Vectrino_Lab_01-2017.pdf

A profiler can be also borrowed from the teaching department: it provides profiles of the three velocity components over 5 cm, useful to study a boundary layer.
