Hydraulics and design of fishways II: vertical-slot and rock-weir fishways
Bibliographic record
Abstract
The pool-type fishway, such as pool-weir, vertical-slot, and rock-weir fishways, is one of the most common fishways that presented the highest efficiency for all fish species. Understanding the flow hydrodynamics inside the fishway is crucial to elicit the fish responses and improve passage for multiple species. This review paper summarizes and discusses the main findings of different research studies on the hydraulics of vertical-slot type technical and rock-weir type nature-like fishways under experimental, numerical, and natural conditions. This paper discusses the effects of geometric characteristics on the pools’ flow patterns, flow regimes, depth-discharge relationships under uniform and non-uniform flow conditions, and maximum velocity prediction methods that are encountered. This review paper synthesizes the long-term advancement of flow hydraulics in vertical-slot and rock-weir fishways, which ultimately will help engineers and fish biologists involved in the design of fishways.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
