Single Large Particle Segregation in Bedload Transport Experiments

Experimental data from a study published in Physical Review Fluids by researchers at the University of Zurich. The repository contains 10 configurations with multiple repetitions, including time-series velocity fields, waterline/bedline positions, and tracked intruder coordinates. Python code is provided to read and plot the data from HDF5 files.

Use Cases

• Analyzing particle segregation dynamics based on tracked intruder coordinates.
• Studying granular bed velocity fields based on interpolated Ux and Uy data.
• Modeling waterline and bedline evolution over time based on the provided position data.
• Validating computational models of bedload transport using the experimental configurations.

Strengths

• Includes 10 distinct experimental configurations covering different size ratios and Shields numbers.
• Provides Python code with annotated classes for reading and plotting the HDF5 data.
• Contains multiple repetitions for each configuration, which may allow for statistical analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
