Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity

An Introduction to Hydropower Concepts and Planning
For example, a 6-foot wide stream with an average depth of 1.5 feet would yield a cross section area of 9 square feet. STEP 3: Measure the Speed. A good way to measure speed is to mark off about a 10-foot length of the stream that includes the point where you measured the cross section.
Hydroelectric power plants are categorized in several types, based on the water head and site conditions. The most important types of hydro power plants are: run-of-river plants, dam plants and pump storage plants. Run-of-river power plants – Figure 5-1 – use the energy of flowing river water to drive hydro turbines to generate electricity.
3 m3/s = 3,000 litres per second. Remember that 1 litre of water weighs 1 kg, so m is the same numerically as the flow rate in litres/second, in this case 3,000 kg/s.
