A new turbine design, which was developed based on sound hydrodynamic principles and existing turbine manufacturing technologies, consists of many original concepts, including the use of vertical upward flow control and elimination of draft tube. These features help to result in water quality improvement in the tail water stream due to increased aeration of the exit flow from the turbine and lowered fish mortality due to smooth flow passage.
