A common question is how to choose streamflow measurement methods and equipment for different flow conditions. Should the stream be waded? Should the measurement be made with moving boat ADCP or Mid-Section ADCP? What track reference should I use if the moving boat ADCP method is used? This presentation will cover the limitations of each approach and introduce a simplified decision matrix for selecting methods and instruments.
The fixed method for making mid-section ADCP measurements is traditionally used for under ice conditions. The fixed method could be adapted to use in open water when other methods will not work due to the inability to safely get top-down observations, magnetic interference, and time constraints. This talk will discuss a situation where the fixed mid-section ADCP method was used in open water when no other viable option was available for making discharge measurements.
A review of what makes up the uncertainty model in QRev, and how a better understanding of the components can help guide the user in rating a measurement.
This presentation provides an overview of extrapolation techniques used in Acoustic Doppler Current Profiler (ADCP) discharge measurements. It examines how QRev and QRevMS streamline the selection and implementation of extrapolation models to estimate discharge beyond the measured dataset. Attendees will gain insight into the available extrapolation settings—including discharge-weighting and custom sub-sectioning—and understand the distinctions between QRev and QRevMS approaches. The session is designed to equip participants with a comprehensive understanding of model selection and settings for accurate discharge estimation.
