Hydropower Effluent as a Marine Pollutant; Impacts of River Regulation on Estuarine and Coastal Ecology

River Research and Applications, Volume 41, Issue 9, Page 1789-1802, November 2025.
ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.

Numerical analysis of energy loss in a laboratory-scale tandem double cylinders based on entropy production method

AIP Advances
Vortex-induced vibration (VIV) to capture low-velocity water current energy has broad application prospects. To utilize low-velocity hydrokinetic energy on a large scale, the energy capture structure should be composed of multiple cylinders.

Design of a new hydrokinetic turbine simulation model based on the extended power coefficient concept

International Journal of Electrical Power & Energy Systems
The operation of hydrokinetic turbines under blockage conditions causes situations where the classical power coefficient does not adequately explain their energy extraction, often exceeding Betz’s limit, as it is referred only to the kinetic energy of ...

Energy Conversion by Helical Hydrokinetic Turbine in A Pipe

Black Sea Journal of Engineering and Science
Hydrokinetic turbines are mechanisms designed for the purpose of utilizing the kinetic energy present in the movement of water bodies like rivers, tidal currents, or ocean currents, and transforming it into electrical power. These turbines’ function based on a principle akin to that of wind turbines; however, they are positioned underwater to harness ...
