Direct Answer-
The turbines can be rotated or spinned as a result of water being introduced to their blades.
Step-by-step explanation-
The turbines are special devices used in hydroelectric generation plants that transfer the energy from moving water to a rotating shaft to generate electricity. These turbines can be rotated or spinned as a result of water being introduced to their blades.
The types of turbines that are selected for any hydropower project is based on the height and speed of the incoming water known as the hydraulic head and the volume of water that flows known as the hydroelectric discharge. The efficiency and its cost are also some factors which makes them important.
