NASH is pleased to announce it will be hosting a Flow Regatta Training event alongside Lethbridge College in sunny Lethbridge, Alberta on Wednesday, July 12th, 2023. The Flow Regatta Training event will take place at the LC Research Farm near the City of Lethbridge from 10 am to 4 pm with lunch and refreshments provided on site. A networking event will follow in the evening in the City of Lethbridge.

Come train alongside industry experts on hydrometric techniques and instrumentation used in low-flow monitoring conditions. The training event focuses on the newest technologies emerging in hydrometrics and allows participants the opportunity to get hands-on training and develop their best practices. Training will be provided on:

  • Salt Dilution: Around for decades, this tried and true method is easy and accurate in turbulent water with cross-channel mixing.
  • ADV Gauging: The evolution of current metering, the newest meters sport automatic depth measurement, Q calculation, and uncertainty estimates.
  • Transparent Head Velocity Rod: This novel technique offers a low-cost alternative to conventional current meters.
  • Submersible ADCP: Ideal for monitoring flows in canals, culverts, pipes, and natural streams.
  • Non Contact Measurements: Including Image Velocimetry (LSPIV, STIV, and SSIV) and Radar: Like ADCP before it, many of the world’s hydrometric agencies are investigated these non-contact, autonomous methods to capture the average surface velocity and estimate the total flow.

Flow regatta training provides an invaluable discussion forum for hydrometric data collection including; how to estimate uncertainty, choosing the best sites to measure discharge using the different methods, and developing best practices for emerging technologies. For those interested in non-contact gauging we will be further researching and providing training on the standardized alpha velocity determination plus our event sponsors will be on hand demonstrating their latest data loggers, hydrometric equipment, and telemetry options.

Participants are encouraged to bring their own instruments to measure and calculate discharge against the known inpipe magmeter. Participants will battle it out for the top prize and bragging rights as they aim to measure, within uncertainty, the objectively determined “true” flow.

Transportation is available upon request. Please bring weather-appropriate clothing and waders.
