Huang, Shih-HsunYang, Judy Q2023-04-262023-04-262023-04-26https://hdl.handle.net/11299/253805We conducted experiments in both permeable and impermeable channel beds, with and without a log jam. Each test yielded three types of data (if applicable): water surface profiles, surface flow measurements, and hyporheic flow measurements using dye visualization.We conducted flume experiments to study how a channel-spanning log jam affects hyporheic flow. 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 beneath the log jam.CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/Large woody debrisLog jamHyporheic flowDatasethttps://doi.org/10.13020/57f0-r060
