Abstracts: Since extra-low head sites of rivers a reavailable near urban-sides with high population, where there is a demand for electricity, an appearance of suitable turbine, which has high cost-effectiveness, maximum reliability, easy maintenance and little environmental impact, is required. In rear part of this project, a guiding principle of design parameters of a Savonius-type water turbine for high performance is shown, based on experi-mental results. Then the advantage and disadvantage of Savonius turbine are reviewed and the key problems, which are settled as urgent works in future in order to diffuse the utilization of extra-low head hydropower, are finally suggested.
