DOI: 10.1007/s10750-020-04376-x
Abstract: Because of growing interest in deploying newer very low head (VLH) turbine technology to generate electricity in rivers, there is a need to assess how fish fare in interactions with VLH turbines. We assessed injury… read more here.

DOI: 10.1016/j.ecoleng.2018.05.028
Abstract: Abstract The number of low-head barriers to fish migration far outweighs the number of large magnitude barriers and thus the cumulative negative impact on fish communities could also be far greater. Removal of man-made obstructions… read more here.

DOI: 10.1016/j.jclepro.2018.10.345
Abstract: Abstract Siphon turbines are an attractive type of small-scale hydropower turbines because they can be retrofitted into existing structures where there is already a drop in water elevation. A siphon turbine conveys water from an… read more here.

DOI: 10.1086/701598
Abstract: The impacts of low-head dams on the genetic structure of small-bodied riverine fishes have not been fully explored. We used both novel and existing microsatellites to assess how 2 low-head dams affect genetic diversity and… read more here.

DOI: 10.1177/09576509221140708
Abstract: Low-head axial flow turbines (LHAFT) are important turbomachines suitable for converting low-head water (potential energy) into mechanical (kinetic) or electrical energy. The performance characteristics of this kind of turbine are an essential aspect of its… read more here.
