Hydropower Biological Evaluation Toolset (HBET) is an integrated suite of software tools designed to characterize hydraulic conditions of hydropower structures that can affect fish passage. HBET provides quantitative estimates of fish injury and mortality rates due to various physical stressors including strike, pressure, and shear.

  • HydroPASSAGE: the HydroPASSAGE project represents the Department of Energy’s Water Power Technology Office’s long-term efforts to develop tools that optimize hydropower turbines for improved downstream fish passage.

The harnessing of flowing water—using a dam or other type of diversion structure—to create energy that can be captured via a turbine to generate electricity.
