Delta Islands and Flood Intermittency: Controlled Flume Experiments

A 1.85 m x 2 m experimental domain with a 50 mm water depth and a 50-mm thick sediment bed was used to study delta island formation. Experiments conducted at the University of Texas at Austin's STEP Basin used a fine quartz sand with a D50 of 171 µm, a flood discharge of 6 l/s, and an interflood discharge of 0.355 l/s. The dataset, authored by Max Daniller-Varghese and last updated in March 2024, likely contains measurements from runs where flood frequency was the sole variable.

Use Cases

• Modeling sediment deposition patterns based on described flood and interflood discharge rates.
• Analyzing the relationship between flood intermittency and island morphology based on the experimental setup.
• Calibrating numerical models of transport-limited flows using the specified sediment properties and basin dimensions.

Strengths

• Describes a controlled experimental setup with precise dimensions (1.85 m x 2 m domain, 50 mm water depth).
• Specifies key physical parameters (sediment D50 of 171 µm, density of 2650 kg/m³, flood discharge of 6 l/s).
• Highlights a single manipulated variable (flood frequency), which likely supports clear causal inference.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for machine learning tasks.
