Flow Structures that Affect the Transport Regime of Large Wood Pieces in a Stream Channel

These files are the dataset (csv files for contour graphics and FFT results) of our research that investigate the flow structures that affect the transport regime of large wood pieces in an open channel. Some files of this dataset which illustrates experimental results were originally published by Akahori et al. (2014). https://doi.org/10.2208/jscejhe.70.I_691 FFT results were corrected to fix units of vertical axes and some errors on lateral axes on 06/16/2022.
