Quantifying and Reducing the Operator Effect in LSPIV Discharge Measurements

Water Resources Research
Operator choices, both in acquiring the video and data and in processing them, can be a prominent source of error in image‐based velocimetry methods applied to river discharge measurements.

Satellite Video Remote Sensing for Estimation of River Discharge

Geophysical Research Letters, 2023
We demonstrate that river discharge can be estimated by deriving water surface velocity estimates from satellite‐derived video imagery when combined with high‐resolution topography of channel geometry.

Exploiting LSPIV to assess debris-flow velocities in the field [PDF]

Natural Hazards and Earth System Sciences, 2018
The assessment of flow velocity has a central role in quantitative analysis of debris flows, both for the characterization of the phenomenology of these processes and for the assessment of related hazards. Large-scale particle image velocimetry (LSPIV)

LSPIV analysis of ship-induced wave wash

Experiments in Fluids, 2022
AbstractShip-induced wave wash affects the hydromorphological and ecological state of rivers through various mechanisms. The direct proximity of the riverbank is usually the most exposed, as the hydrodynamic stresses are the highest in these shallow water areas.
