Stream Discharge Measurement Using A Large-Scale Paticle Image Velocimetry Prototype
… flow is Large-Scale Particle Image Velocimetry (LSPIV). LSPIV is a system capable of measuring surface velocity by collecting and analyzing recorded images of the stream surface. LSPIV has several advantages over conventional discharge measurement techniques: LSPIV is safer, could be automated to …

Measuring flow and mixing at stream confluences using large-scale particle image velocimetry, in-stream techniques, and small unmanned aerial systems
… are to: 1) investigate the accuracy of LSPIV for characterizing two-dimensional patterns of surface flow at stream confluences and 2) to use in-stream measurements of three-dimensional velocity, temperature, and turbidity to characterize mixing patterns and rates at confluences and to …

High-resolution spatial and temporal evolution of two-dimensional flow structure at a small stream confluence
… in Large-Scale Particle Image Velocimetry (LSPIV) have created novel opportunities to explore the spatial and temporal dynamics of flow patterns at confluences. This study uses LSPIV to map two-dimensional flow structure at the water surface and to examine variation in this structure over …

Physical suitability of sites for community-scale tidal power generation
… allowing large-scale particle image velocimetry (LSPIV) to be applied to georectified images of these tidally energetic sites. This provides a novel site assessment tool, using the advected surface signature of turbulent structures to infer a highly-resolved, site-wide measurement of surface …

Inference of River Hydrodynamics and Ice Processes from Close-Range Remote Sensing
… optical flow, Large scale Particle Imagery (LSPIV) and Space Time Image Velocimetry (STIV) methodologies, with a significantly higher estimation accuracy than both LSPIV and STIV, with approximately 25% and 15% higher accuracy respectively for LSPIV and STIV. In conclusion, this thesis …
