New Surface Velocity Guidelines – Setting the standard internationally!

Mark Randall - Department of Regional Development, Manufacturing and Water QLD , 30 September, 2021

We are pleased to announce that WaMSTeC members have endorsed a new National Industry Guideline document, Part 11: Application of Surface Velocity Methods for Velocity and Open Channel Discharge Measurements. This is the first Standards Document in the world to govern the data collection and processing of surface velocity measurements using image velocimetry and surface velocity radar (Figures 1-2).

This document has been developed over the past 15 months by a voluntary Technical Reference Group (TRG) of leading industry experts. Particular thanks go to the two primary authors responsible for writing the document’s technical content as part of the TRG.

Mark Randall of the Queensland Department of Regional Development, Manufacturing and Water is the guideline sponsor and has collected and validated thousands of image velocimetry discharge measurements using both drones and fixed cameras since 2016. Mark provides training and guidance to government monitoring agencies from around the world on how to use these techniques.

Mic Clayton from Snowy Hydro has been operating radar-based systems over a number of years developing considerable experience and knowledge on how to achieve the best from these systems.
