A Review of Particle Image Velocimetry for Fish Migration

Abstract

Understanding the flow characteristic in fishways is crucial for efficient fish migration. Flow characteristic measurements can generally provide quantitative information of velocity distributions in such passages; Particle Image Velocimetry (PIV) has become one of the most versatile techniques to disclose flow fields in general and in fishways, in particular. This paper firstly gives an overview of fish migration along with fish ladders and then the application of PIV measurements on the fish migration process. The overview shows that the quantitative and detailed turbulent flow information in fish ladders obtained by PIV is critical for analyzing turbulent properties and validating numerical results.

Past and current components-based detailing of particle image velocimetry: A comprehensive review

“…PIV has a wide range of application areas and is utilized to analyze various flows such as turbulent flow, micron-scale systems, spray atomization, and combustion processes [ 8 ]. The technique is also utilized for various sectors like education [ 9 ], mining [ 10 ], hydrology [ 11 ], heat exchangers [ 12 ], nuclear reactors [ 13 ], aviation [ 14 ], chemical engineering [ 15 ], air conditioning, and ventilation [ 16 ] directly or indirectly from subsonic flows to supersonic flows, the technique finds an application area [ 8 ].…”

Challenges with Regard to Unmanned Aerial Systems (UASs) Measurement of River Surface Velocity Using Doppler Radar

“…Measurements of surface velocity in rivers are essential to evaluate sediment deposition and erosion processes [1,2] especially during high flow periods [3], study fish migration [4][5][6] and estimate discharge [7][8][9][10][11][12]. In shallow rivers, where the operator can wade through, velocity is generally measured with a velocity probe (propeller-based or electromagnetic instruments), whilst Acoustic Doppler Current Profiler (ADCP) is typically used in rivers with depths larger than 1-2 m. Researchers have also experimented with contactless techniques for measuring surface velocity, such as optical and radar methods.…”
