Low Head turbines are hydropower turbines which have been developed for
small-scale exploitation of rivers or irrigation canals. They have been
developed for low water heads - below 10 metres - but large flows of
water. Examples of their use in South America, Asia and Europe are
given. The three types of low head turbines - crossflow turbines, kaplan
turbines and propeller turbines- , and their applications, are
described. Costs, suitable locations, power generated, and the special
requirements of the two commercially available low head turbine models
(LH1000 and PowerPal turbines) are discussed.
