Dataset for "Hydraulic-field energy-flux-state reorganization during alternate-bar formation in a mobile-boundary open-channel flow"

This dataset supports the Physics of Fluids manuscript "Hydraulic-field energy-flux-state reorganization during alternate-bar formation in a mobile-boundary open-channel flow" by Daichi Moteki, Shohei Seki, and Hiroyasu Yasuda. The record contains processed experimental and hydraulic-reconstruction data for movable-bed open-channel flow experiments on alternate-bar formation. The dataset includes a hydraulic-condition table for 16 experimental conditions and a compressed archive of 64 bundled Python pickle files, corresponding to four replicate runs for each condition. Each file contains gridded bed-elevation and reconstructed depth-averaged hydraulic-field data, reach-scale mechanical-energy-flux measures, depth--discharge-intensity covariance diagnostics, and local-update accounting terms used in the manuscript figures, tables, and analyses. The release contains processed data only. It does not include the original raw iRIC/VTK files, raw image/measurement files, or preprocessing/analysis scripts. The data are based on measured bed-elevation snapshots and quasi-steady two-dimensional depth-averaged hydraulic-field reconstructions.
