The Institute has been conducting research in support of hydropower since the early 1960s. Its research and development activities cover methods for designing and analysing flow systems of water turbines, development of measurement and diagnostic methods, investigation of cavitation, cavitation erosion and water hammer phenomena, as well as prevention and mitigation of the effects of these phenomena. Its service activities include expert assessments, design work, and energy and diagnostic testing of hydro-units in hydropower plants.
