River gauging techniques – Helicopter

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 (http://www.orc.govt.nz/).

I came across the link at Stu Hamilton’s blog (http://www.aquaticinformatics.com/blog/hydrology-heli-gauging/)

What do you think about its potential for measuring peak discharge in some of the remote rivers in Alaska or other places?

Cheers.
