A visual field guide to indexing fluid dynamics for fish passage continuity.
Review of the NIWA NZ Fish Passage Guidelines
The NIWA NZ Fish Passage Guidelines aim to improve aquatic connectivity for native fish species across human-made barriers, but fall short in scientific robustness and practical utility. Key shortcomings undermine their effectiveness, particularly given New Zealand’s unique freshwater ecology and the diversity of instream structures found in its waterways.
Computaional Fluid Dynamics (CFD ) Simulation
This report presents simulation results and demonstrates the capability of CFD as a tool for evaluating culvert hydraulics, showing the complexities required for successful fish migration and informing baffle design decisions.
Reframing Fish Passage – From Single Metric to Structured Complexity
Fish passage design has long measured the wrong things – structured flow complexity, not average velocity, is what actually gets fish upstream.
