Fish Passage Behavior at Hydropower Bypass Gates with Bottom and Top Openings

A 2026 study by Maximilian Kastinger quantifies fish guidance structure performance at hydropower plants. It includes hydraulic measurements and ethohydraulic tests with brown trout and common barbel, assessing bypass entrance efficiency under different gate configurations. The dataset contains video files and documents totaling 237.6 MB.

Use Cases

• Modeling fish bypass entrance efficiency based on hydraulic parameters like velocity ratios and streamwise velocity gradients.
• Comparing species-specific passage behavior (brown trout vs. common barbel) in response to different gate opening geometries.
• Evaluating design recommendations for fish guidance structures by analyzing measured bypass inflow velocities against established thresholds.
• Training machine learning models to classify fish avoidance behaviors in high-velocity flows from video data.

Strengths

• Includes quantified hydraulic measurements (bypass inflow velocities up to 2.0 m/s, velocity ratios up to 6.7, streamwise velocity gradients up to 21 s−1).
• Reports species-specific bypass entrance efficiency results (BO: 27–59%; TO: 8–21%).
• Provides video data (MP4 files) of fish behavior for visual analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect bias inherent to the specific experimental setup and species tested.
