Hydroacoustic Streamflow Measurements: Selecting Equipment and Methods
Wednesday July 22, 2026 8:00am - 8:20am CDT
BCC - Birmingham (65 Class / 100 theater)
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.

Using the Fixed Method for Open Water Mid-Section ADCP Measurements
Wednesday July 22, 2026 11:00am - 11:20am CDT
BCC - Birmingham (65 Class / 100 theater)
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.

Streamflow Measurement Uncertainty: How do I rate this ADCP measurement?
Wednesday July 22, 2026 3:00pm - 3:50pm CDT
BCC - Birmingham (65 Class / 100 theater)
Excellent? Good? Fair? Poor? Computing the uncertainty of an ADCP moving-boat discharge measurement is a complex task. This session will review 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.

Understanding ADCP Extrapolations in QRev and QRevMS
Wednesday July 22, 2026 4:00pm - 4:20pm CDT
BCC - Birmingham (65 Class / 100 theater)
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.

Using AreaComp3 for Indirect measurements
Wednesday July 22, 2026 4:30pm - 4:50pm CDT
BCC - Birmingham (65 Class / 100 theater)
AreaComp3 was primarily developed to assist with development of Stage-Area ratings for index velocity sites. The program has several other improvements that can assist with the computation of Indirect measurements, specifically Contracted Opening and Critical Depth measurements. This brief presentation will discuss the use of the AreaComp3 tool with X,Y,Z data, and how you can use that output to assist with the computation of Indirect Measurements. This presentation is geared towards users that collect cross section data post flood and need to compute hydrologic properties with that data. It is also oriented towards technicians/hydrologists that work with Indirect Measurements of Discharge and should be familiar with those methods.
