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)

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.
