Alpha Coefficient Data Mining for Image Velocimetry from the USGS Database of ADCP Measurements
Tuesday July 21, 2026 1:30pm - 1:50pm CDT
BCC - Lackey (54 Tiered Class Only)
To compute discharge using image velocimetry, the measured surface velocity must be related to the depth-averaged velocity; this is typically done using a simple coefficient known as the alpha coefficient. The alpha coefficient is the most significant input to the computation of discharge from imagery that is often not empirically determined, but the resulting discharge value is directly proportional to the value chosen. The USGS database contains more than half a million ADCP measurements - the profiles in these measurements can be used to inform selection of alpha. Results from a compilation of profiles at a variety of sites will be presented.

USGS Water Data in Relation to the Fundamental Science Practices
Tuesday July 21, 2026 3:00pm - 3:20pm CDT
BCC - Nichols (21 Class / 40 Theater)
The USGS has collected water data for over 135 years. The USGS Fundamental Science Practices (FSP) have been governing water data collection and publication for the past 20 years. How familiar are you with FSP as it pertains to water data? This presentation will (1) provide a broad overview of FSP, (2) show how FSP relates to water data collection and subsequent data publication, and (3) share available OSQI resources useful for when FSP questions arise.

This presentation will accomplish these objectives by examining three focus areas; (1) discussing data collection and approval obligations in SM 502.2 Fundamental Science Practices: Planning and Conducting Data Collection and Research and SM 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release, (2) relating adherence of Water Mission Area Techniques and Methods to adherence of Fundamental Science Practices, (3) discussing mechanisms for reporting FSP questions to the Fundamental Science Practices Advisory Council (FSPAC), quality concerns to OSQI resources, and integrity concerns to the USGS Scientific Integrity Officer. Listeners will leave the presentation with a better understanding of how FSP relates to USGS Water data collection and publication and where to turn to when concerns arise.

This presentation will be given by Gary Burke, a staff scientist from the Office of Science Quality and Integrity (OSQI). Gary was a Field Office Chief for over 6 years prior to joining OSQI and had collected NWIS water data for over 20 years.

ICE-Edge: Computing Continuous Under-ice Discharge on the Edge
Wednesday July 22, 2026 10:00am - 10:20am CDT
BCC - Lackey (54 Tiered Class Only)
As of Jan 5, 2026, 1,185 of the 9,004 USGS streamgages were ice-affected - approximately 13.2% of our assets that lack the capacity to deliver real-time discharge. Existing USGS under-ice methods require hours to complete, are cost prohibitive, lack the capacity to deliver continuous discharge time series, and place hydrographers at risk. ICE-Edge computes real-time under ice discharge on the “edge” (think by the riverbank) by integrating a RaspberryPi (RPi) computer, python code, uplooking Acoustic Doppler Velocity Meter (u-ADVM), FirstNet modem, and leveraging the probability concept discharge algorithm.

What to do after you’ve measured the “big one”: USGS peak-flow data for Hydrologic Technicians
Wednesday July 22, 2026 10:00am - 11:20am CDT
BCC - Wilson (54 Tiered Class Only)
Annual peak streamflow data from USGS streamgages are a critical dataset engineers and hydrologists use for flood frequency analyses that inform bridge designs, floodplain maps, and other projects in and along rivers. Updated Federal guidelines for flood-frequency analysis (Bulletin 17C) were released in 2019, which allow for better use of information published by the USGS, such as censored (greater than or less than) data, and data sources outside of streamgage records, such as historic peaks. In this workshop, attendees will learn how annual peak-flow data are used, what peak flow qualification codes mean and when to use them, what flood information should be included in station descriptions and manuscripts in SIMS, the proper application of “highest since” notes to annual peaks, proper treatment of peak flows at crest-stage gages, and lots of other flood-related facts. An example streamgage will be analyzed with the PeakFQ software to demonstrate application of USGS data to a real-world flood-frequency problem.

Standard streamgaging methods to compute discharge rely on placing equipment and personnel in water and integrating velocities and depths at multiple verticals at a channel cross section (25 to 30 to hundreds of hydroacoustic ensembles). However, a paradigm change has occurred with the advent of non-contact platforms such as fixed‑mount and portable velocity radars and drone‑based cameras. The benefits of coupling these platforms and novel algorithms are clear – enhanced safety and increased efficiency.

From Field Survey to Plotted Cross-Section: SVMobileAQ Data Collection and AreaComp3 Visualization
Thursday July 23, 2026 8:00am - 8:50am CDT
BCC - Birmingham (65 Class / 100 theater)
Accurate and efficient cross-section surveys are essential for maintaining high-quality stage-discharge ratings and index velocity gage operations. This presentation demonstrates a streamlined workflow for conducting differential level surveys of river cross-sections using the SVMobileAQ mobile application and importing the data into AreaComp3 software for visualization and analysis.
The session will cover the fundamentals of setting up a conventional differential level instrument (level gun) and collecting cross-section data in the field with SVMobileAQ. Attendees will then learn how to seamlessly import the survey data into AreaComp3 to generate plotted cross-sections referenced to gage datum.
Although commonly applied to index velocity gages, this approach provides broader benefits for streamgaging programs, including evaluation of control features at stage-discharge stations, detection of changes in channel geometry through overlay of historical surveys, and investigation of discrepancies by comparing survey results with ADCP bathymetry.
This practical, field-to-office workflow offers an accessible and efficient method for improving the quality and utility of cross-section data in water resources monitoring.

This talk is a hands on introduction to three geophysical methods, time-domain and frequency-domain electromagnetic (TDEM and FDEM) methods, along with the horizontal to vertical spectral ratio (HVSR) method that are increasingly useful for groundwater investigations. We focus on how these methods work, what they measure, how they’re deployed in the field, and the subsurface information they provide. Case studies highlight how electromagnetic methods can map subsurface conductivity and characterize aquifers, and how the HVSR passive seismic technique helps estimate sediment thickness overlying bedrock, an important input for groundwater modeling.

Unified Field Data Collection Application- Status Update
Thursday July 23, 2026 10:00am - 10:20am CDT
BCC - Sellers (476 Class / 800 Theater)
Like a lot of things, the Unified Field App (UFA) project has navigated several challenges in the last year. This means we've had to push the groundwater module release date until sometime well into 2027. 

Despite these setbacks, the team has kept momentum moving forward. We're using 2026 to re-group, refine our strategy, and set the project up for success in 2027 and beyond.  

Most importantly, the project is still moving forward (though slower than planned) and is recognized as a high priority. We appreciate your patience and continued enthusiasm.
