Dataset for: A multi-scalar diagnostic framework for the transfer of hydrodynamic forcing to bank erosion in transitional rivers

This dataset contains the pre-processed intermediate geomorphic and topological data required to replicate the analysis and figures in the manuscript: "A multi-scalar diagnostic framework for the transfer of hydrodynamic forcing to bank erosion in transitional rivers" (Song et al., submitted to Earth Surface Processes and Landforms). Due to the file size limitations of raw Landsat-derived annual active channel masks (GeoTIFFs, several gigabytes), this dataset provides pre-extracted topological networks and curvature/width profiles to ensure full reproducibility without requiring large-scale raster processing. DATASET CONTENTS:The archived intermediate_results.zip (approximately 200 MB) contains the following directories structured for the project pipeline:1. RivGraph/ — Topological node-link centerline networks extracted from annual active channel masks (2000-2025) using the RivGraph package. Provided as shapefiles (links and nodes) for the three study reaches:- Yellowstone River (Montana, USA)- Ucayali River (central Peru)- Lower Yellow River (Gaocun-Sunkou reach, China)2. profiles/ — Extracted annual centerline geometry profiles in CSV format containing local channel width (B*), local curvature (C*), and width anomaly (nu) sampled at 100-meter intervals.3. banklines/ — Annual outer-bank and inner-bank migration rate polygons (M) in shapefile format computed via the polygon-area method.4. Cache/ — Compiled node-scale and bend-scale database tables containing near-bank excess velocity (Delta U), migration rate (M), NDVI, and Bar Exposure Ratio (BER) values used for statistical quantile regression. USAGE INSTRUCTIONS:1. Clone the associated code repository from GitHub: https://github.com/sxlong2022/transitional-river-erosion-diagnostics2. Download and extract this intermediate_results.zip archive.3. Place the extracted RivGraph/, profiles/, and banklines/ folders directly into the results/ directory of the cloned repository.4. Run "python -m src.stability.run_beta_sweep" (Step 2 in README.md) to initiate the physics-based hydrodynamic modeling and regenerate the results.
