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.

Discharge estimation in small irregular river using LSPIV [PDF]

Proceedings of the Institution of Civil Engineers - Water Management, 2010
This paper reports on an estimation method used to quantify discharge in the small irregular channel of the River Blackwater, using large-scale particle image velocimetry (LSPIV). The test reach (250 m × 60 m) consists of relatively straight and multiple meander channels, with a bankfull depth of 0·90 m and a base width of 4·25 m.
