IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Efficiency of traditional water wheels
For centuries mankind has used water wheels as a source of mechanical power for mills, weaving factories and machine
workshops. By the time theories and manufacturing methods of water wheels improved; the most developed technology
took a significant leap into the turbine at the end of the Nineteenth century and water wheels development ceased [5] [6].
Thanks to a new sensibility to renewable energy and to local and smart electricity production, traditional water wheels are regarded again as a clean and accessible way for micro electricity generation from water, especially in sites with very low heads, improving local economy and sustainable development. Water wheels have several advantages over turbines, such as lower environmental impacts, simpler technology, faster pay back periods and the less public resistance to their installation. Unfortunately, few model experiments have been carried out on water wheels and there is still much uncertainty about their optimal working conditions and performance characteristics [7].
Since the lack of knowledge in the engineering profession, the research project ORME (Energy optimization of traditional water wheels) aims at studying the performance characteristics of water wheels and their hydraulic and mechanical optimization by means of theoretical models and numerical (CFD) simulations.
