Cross-flow turbine: Also known as Banki-Mitchell or Ossberger turbines, these devices are used for a large range of hydraulic heads (from 2 to 100 meters) and flow rates (from 0.03 to 20 m 3 /s), but are more efficient for low heads and low power outputs. They are considered "impulse" turbines, since they get energy from water by reducing its ...
In low-head installations, maintenance and mechanism costs can be relatively high. A low-head system moves larger amounts of water, and is more likely to encounter surface debris. For this reason a Banki turbine also called Ossberger turbine, a pressurized self-cleaning crossflow waterwheel, is often preferred for low-head micro hydro systems ...
A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in). This technology is based ...
Run in reverse, Archimedes screw turbines act as a new form of small hydroelectric powerplant that can be applied even in low head sites. Such generators operate in a wide range of flows (0.01 / to 14.5 /) and heads (0.1 m to 10 m), including low heads and moderate flow rates that is not ideal for traditional turbines and not occupied by high ...
The Archimedean screw turbine is applied on rivers with a relatively low head (from 0.1 m to 10 m) and on low flows (0.01 m 3 /s up to around 10 m 3 /s on one turbine). Due to the construction and slow movement of the blades of the turbine, the turbine is considered to be friendly to aquatic wildlife. It is often labelled as "fish friendly".

Most water turbines in use are reaction turbines and are used in low (<30 m or 100 ft) and medium (30–300 m or 100–1,000 ft) head applications. In reaction turbine, pressure drop occurs in both fixed and moving blades. It is largely used in dam and large power plants.
Small power plant of Licq-Athérey (Pyrénées-Atlantiques, France). An 1895 hydroelectric plant near Telluride, Colorado.. Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. [1]
