River gauging techniques – Helicopter

I am always interested in the different techniques that are being used to measure stream discharge.  Sometimes, it can be quite difficult to access rivers in areas with good access, non-mobile beds, stable cross-sections, and a host of other site conditions that make for good channel cross sections.  Well, here is a New Zealander’s approach that uses a helicopter, a modified whitewater kayak, and an ADCP unit to measure stream discharge.  The group is out of the Otago Regional Counil (
