LSPIV analysis of ship-induced wave wash
Experiments in Fluids, 2022 Ship-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.

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.

Integrating unmanned aerial systems and LSPIV for rapid, cost-effective stream gauging
Journal of Hydrology, 2018 Abstract Quantifying flow in rivers is fundamental to assessments of water supply, water quality, ecological conditions, hydrological responses to storm events, and geomorphological processes. Image-based surface velocity measurements have shown promise in extending the range of discharge conditions that can be measured in the field.

Assessing different imaging velocimetry techniques to measure shallow runoff velocities during rain events using an urban drainage physical model [PDF]
Hydrology and Earth System Sciences, 2021 Although surface velocities are key in the calibration of physically based urban drainage models, the shallow water depths developed during non-extreme precipitation and the potential risks during flood events limit the availability of this type of data ...
