·         The Kaplan turbine is a propeller-type water turbine that has adjustable blades. It was developed in 1913 by the Austrian professor, Viktor Kaplan.

·         The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low head applications that was not possible with Francis turbines.

·         Kaplan turbines are now widely used throughout the world in high flow, low head power production.

·         Power plants operate with net heads ranging from 33 to 230 ft (10 to 70 m).
