Introduction to TRiVIA: The Toolbox for River Velocimetry using Images from Aircraft
Wednesday July 22, 2026 8:00am - 8:50am CDT
The Toolbox for River Velocimetry using Images from Aircraft (TRiVIA) provides an end-to-end workflow for mapping velocities in rivers from videos or image sequences. The software includes modules for extracting frames, stabilizing and geo-referencing images, defining a region of interest, enhancing images, performing particle image velocimetry (PIV), visualizing results, assessing accuracy, and calculating discharge. In this introductory session, we will provide a brief overview TRiVIA's capabilities using an example data set from a river in Oregon collected using an uncrewed aircraft systems (UAS). Our target audience is any hydrologist who wants to learn about image-based techniques for estimating flow velocities in rivers.

Daily Rainfall Instrument Performance (DRIP): An Automatic Workflow to QA/QC Precipitation Station Data
Wednesday July 22, 2026 8:30am - 9:20am CDT
Precipitation is a challenging parameter to model and measure accurately, making in situ observations from networks, like the approximately 3,400 USGS precipitation stations, especially valuable. Ensuring the accuracy of these observations is critical, particularly because provisional data is made publicly available in near real time. Station measurements are affected by various types of errors, several of which occur randomly in an unpredictable manner. The DRIP application is a threshold-based tool that leverages existing NOAA and USGS data to automatically identify potentially anomalous measurements to help maximize station uptime, prevent skewing of precipitation totals, and streamline field response.

Introduction to the Salt Dilution Streamflow Method
Wednesday July 22, 2026 2:30pm - 3:20pm CDT
The salt dilution method is a technique for measuring streamflow by injecting a trace pulse of sodium chloride (NaCl) into a stream, allowing it to fully mix, and tracking the downstream dilution through changes in specific conductance. Because salt dilution performs well in turbulent or irregular flow conditions where velocity–area methods often fail, it is a practical option for difficult‑to‑measure sites. This presentation introduces the salt dilution method, including how to identify suitable site conditions, the core field procedures for making salt dilution measurements, and the principles behind salt dilution discharge calculations.

USGS Coastal Storm Team – Update
Wednesday July 22, 2026 3:00pm - 3:50pm CDT
Since the deployment of the first pressure transducer to record continuous water levels during Hurricane Rita, the USGS has made steady advances in the collection of storm tide and wave data. These efforts have improved the agency’s ability to document coastal storm conditions and support understanding of storm-driven coastal processes.
This session will provide updates on the USGS Coastal Storm Team, including recent progress in field data collection, instrumentation, and operational coordination. It will also highlight emerging ideas and future directions for enhancing USGS capabilities in coastal storm monitoring and response.

Image-Based Stage Estimation
Wednesday July 22, 2026 3:00pm - 3:50pm CDT
This presentation explores image-based stage estimation as a scalable alternative to traditional sensor networks, evaluating multiple approaches across a network of USGS monitoring sites with fixed-mount cameras. First, commercially available optical gaging software, Tenevia and Noema, are assessed for operational viability and accuracy against sensor-derived stage data. Second, a deep learning regression model (EfficientNet-B0) is trained to predict gage height directly from full scene imagery. Third, a computer vision segmentation pipeline targeting USGS staff plates extracts the air-water interface to derive stage through physical image measurements.

A Solution Thirty Years in the Making: The Fargo-Moorhead Diversion Project
Wednesday July 22, 2026 3:00pm - 3:50pm CDT
After the devastation of the 1997 flood, there was agreement in the Fargo-Moorhead community that something needed to be done to prevent a repeat of the catastrophic damages. Planning began for what would become the FM Area Diversion. The process has included studies, permits, Congressional action and hard work from many key entities, including the USGS. Now, the community is on track to have permanent, reliable flood protection by 2027. This presentation will outline the project and USGS's involvement leading up to, during, and post project development.

Understanding Moving Boat and Mid-Section ADCP Extrapolations
Wednesday July 22, 2026 4:00pm - 4:20pm CDT
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.

Flow Photo Explorer: Using Trail Cameras to Estimate Streamflow Dynamics
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
This session introduces the Flow Photo Explorer (FPE)—a USGS tool that uses time-lapse trail camera images to estimate relative streamflow dynamics, especially in ungagged streams and now deployed at 600+ locations. We’ll show how simple imagery can be turned into flow models and highlight ongoing work expanding these methods. The session includes a live demo of the platform so you can see how it works in practice, along with examples of where it’s been useful and what’s coming next.

Listening Session – Ideas for integrating satellite imagery with existing workflows and applications
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
High resolution satellite data has the potential to enhance situational awareness, aid in interpreting signals from monitoring stations, and in understanding environmental conditions when working records. However, access to high resolution satellite imagery is currently separate from most day-to-day workflows for field staff. In this listening session we will review available high resolution satellite imagery, gather ideas of how they might be used in field operations and records processing, and explore where they might plug into existing applications. Through collaborative idea generation, we will explore the question "In day-to-day workflows, where and how would it be helpful to have satellite imagery available?” The outcome will be a collective vision of a future where satellite data are delivered at the point(s) of greatest utility to support mission essential hydrologic monitoring tasks.
