Experimental data of the log-induced hyporheic flow experiment in the 6-inch flume of St. Anthony Falls Laboratory in 2023

We conducted flume experiments to study how two in-line channel-spanning logs affect surface flow and hyporheic flow in a channel. The dataset comprises data and results obtained from measurements of water surface elevation profiles, particle image velocimetry (PIV) measurements, and visualizations of fluorescent dye transport in the sediment bed around the channel-spanning log. The Matlab scripts used to process the data are also included.
