Computational fluid dynamics (CFD) models numerically simulate the flow of water through turbines in accordance with equations of fluid motion that are based on physical properties such as velocity, pressure, temperature, density and viscosity.

The physical contact between a fish and physical structures (e.g. wicket gates, turbine blades) during hydropower turbine passage. This can result in injury and/or mortality for fish passing through the turbine environment. BioPA and HBET measure the occurrence and magnitude of collisions for fish in the environment.
