This session presents recent validation results for IVyTools and evaluates the performance of Space-Time Image Velocimetry (STIV) methods across a range of hydraulic conditions. We will review findings from our internal comparison study, highlight accuracy metrics derived from controlled field and laboratory datasets, and demonstrate how the Comparison Measurement Database supports transparent evaluation of IVy-derived velocities. The session will also introduce the latest improvements to IVyTools processing workflows, including enhanced guidance on interpreting “dots” visualizations for QA/QC. Attendees will gain a clearer understanding of the strengths, limitations, and reliability of STIV-based velocity measurements and how to apply the tools confidently in operational settings.
