Abstract Large-Scale Particle Image Velocimetry (LSPIV) has been successfully applied for stream flow and flood measurements. In most LSPIV studies, the water surface has been approximated as a two-dimensional planar surface. Errors may arise due to this approximation for flows in steep channels and with complex riverbed topography, especially for ...

LSPIV implementation for environmental flow in various laboratory and field cases [PDF]
Journal of Hydro-Environment Research, 2011 Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different environmental flow and hydraulic engineering applications for the investigation of complex ...

Increasing LSPIV performances by exploiting the seeding distribution index at different spatial scales [PDF]
Journal of Hydrology, 2021 Image-based approaches for surface velocity estimations are becoming increasingly popular because of the increasing need for low-cost river flow monitoring methods. In this context, seeding characteristics and dynamics along the video footage represent one of the key variables influencing image velocimetry results.

The Use of LSPIV to Measure Large Streamwise Vortices
World Environmental and Water Resource Congress 2006, 2006The impact of large streamwise vortices or macroturbulence upon suspended sediment transport and mobility of aquatic species is well recognized. In order to advance the understanding of large streamwise vortices, it is increasingly important to map the turbulent structures on a large scale domain such as for a total river reach.

Advantages of a mobile LSPIV method for measuring flood discharges and improving stage–discharge curves [PDF]
Journal of Hydro-Environment Research, 2011 Abstract This paper investigates the potential of fast flood discharge measurements conducted with a mobile LSPIV device. LSPIV discharge measurements were performed during two hydrological events on the Arc River, a gravel-bed river in the French Alps: a flood greater than the 10-year return period flood in May, 2008, and a reservoir flushing ...

Verification and Application of Surface-Velocity Measurement Method Using LSPIV [PDF]
Journal of Korea Water Resources Association, 2004 The purpose of this study is to verify LSPIV technique. Verification was made using moving cart with known velocity. The difference of velocity values obtained using these methods are within 5％, which means that LSPIV can be used in the field with ...
