Introduction to TRiVIA: The Toolbox for River Velocimetry using Images from Aircraft
Wednesday July 22, 2026 8:00am - 8:50am CDT
BCC - Mason (33 Class / 60 Theater)
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.

Stream2Screen: Streamlining Gage Management with a Real-Time Push Notification System
Wednesday July 22, 2026 9:00am - 9:20am CDT
BCC - Mason (33 Class / 60 Theater)
Efficiency isn't just a goal-- it's a necessity when managing a large network of gages. Manual checks and generic station-health emails are so last century.
We've integrated custom programming into our internet-connected dataloggers to improve our standard monitoring workflow. By utilizing an open-source web server and HTTP PUSH/POST methods, we send push notifications to "subscribed" users. Notifications are completely customizable and end-users only "subscribe" to gages that they run or are interested in. They receive instant notifications if there are instrument-specific issues, total system failures or peaks in parameters that should be targeted. With custom messaging, we also build in troubleshooting tech-tips. No more generic "Low Battery" message; users get specific messaging containing diagnostic tips and the likely culprit for the issue or failure. Our gages don't just record data; they advocate for their own maintenance and targeted sample scheduling.

Image-Based Stage Estimation
Wednesday July 22, 2026 3:00pm - 3:50pm CDT
BCC - Mason (33 Class / 60 Theater)
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.

Flow Photo Explorer: Using Trail Cameras to Estimate Streamflow Dynamics
Wednesday July 22, 2026 4:00pm - 4:50pm CDT
BCC - Mason (33 Class / 60 Theater)
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.
