Issued by Fisheries and Oceans Canada, this research contract focuses on experimental and numerical investigations into how hydrodynamics, specifically turbulence and eddies, influence bypass designs for downstream migrating fish. The primary goal is to enhance fish passage efficiency and safety to reduce injury and mortality rates at various obstructions. The project will be performed in Manitoba, Canada, and involves a combination of physical modeling and advanced computational analysis. The scope of work includes conducting literature reviews, fabricating modified spillways and bar rack models, and utilizing stereoscopic particle image velocimetry for three-component velocity measurements. Researchers will analyze velocity data to determine how flow acceleration and turbulence affect fish swimming behavior. Additionally, the contract requires the creation of benchmark databases to validate three-dimensional computational fluid dynamics models and the performance of CFD analysis across various spillway designs to optimize hydrodynamic conditions for fish migration.

Full Description

Show more
The purpose of this research contract is to perform experimental and numerical investigations to understand the role of hydrodynamics, including turbulence and turbulence eddies, on bypass designs for downstream migrating fish. Fish passage efficiency and effectiveness for ways to divert or guide fish downstream at obstructions have varied for many species. This research aims to improve conditions for safer passage of fish through bypasses to minimize injury or mortality risks.The work comprises of the following: a) conduct literature review, design and fabricate modified spillways and bar rack models; b) conduct three-component velocity measurements using a sophisticated stereoscopic particle image velocimetry system; c) perform comprehensive and sophisticated analysis of the velocity data to understand the hydrodynamics, turbulence characteristics and turbulence eddies; d) assess how changes in hydraulic conditions, especially flow acceleration, turbulence and eddies, affect swimming behavior and movement of downstream migrating fish, e) create repository of comprehensive benchmark databases to validate three-dimensional computational fluid dynamics models for understanding the hydrodynamic conditions at bypass entrances which favour downstream fish migration, f) perform literature review to assess predictive performance of various computational fluid dynamics models, g) perform computational fluid dynamics analysis of turbulent flow over various spillway models.
