Option 1 : Kaplan turbine

Concept:

Kaplan turbine is an axial flow reaction turbine in which the water flows parallel to the axis of rotation of the shaft. For Kaplan, both the kinetic and potential energy is available at the inlet.
Kaplan turbine has adjustable moving blades and so it is also known as a variable pitch propeller turbine.
Axial flow reaction turbine has less number of blades and thus the friction loss will be lesser and it can work on low head producing high discharge and high specific speed. But this is susceptible to cavitation.

∴ Kaplan turbine is a propeller turbine in which the vanes fixed on the hub are adjustable.
