Leaky barrier fish behaviour and velocity measurement data

Fish movement of Atlantic salmon (salmo salar) in response to a porous and non-porous model leaky barrier was investigated under bankfull (100%) and near bankfull (80%) flow condition. Results are published in https://doi.org/10.1098/rsos.201843. Experimental data are available online as electronic supplementary material (https://doi.org/10.1098/rsos.201843) and under (http://doi.org/10.17035/d.2021.0129240456). The excel file consists of fish behaviour data and hydrodynamic measurement data.

Fish behaviour results are present for both flow conditions and all treatments (control (no leaky barrier), porous and non-porous leaky barrier) and summarise time spent upstream, downstream and underneath the leaky barrier, number of upstream passes, fish length and information about human interaction applied during the test as well as further remarks. 

Using acoustic Doppler Velocimetry measurements, upstream and downstream time-averaged mean streamwise velocities were recorded at four measurement locations for the porous and non-porous leaky barrier and at one measurement location for the control case under bankfull and near bankfull discharge.
