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.

ABSTRACT
Oscillating Water Column (OWC) is one of the most promising wave energy conversion technologies. It consists on a half-submerged chamber with an air-turbine installed on the top and connected to an electric generator. Incident waves make oscillate chamber interior free surface and air is pushed to circulate through the turbine making it rotate. During the last decades some OWC prototypes have been tested in the sea, but the technology has not yet reached the commercial stage. Therefore, it is necessary to deepen in the knowledge of the problem by means of tools that do not involve the high costs of full-scale construction. The main objective of this work is to propose a hybrid methodology of numerical and experimental modelling of OWC systems from the early stages of the development to the most advanced ones, searching the equilibrium between available resources and required accuracy of each stage. In this paper a combination of frequency domain analysis, simplified time-domain models, CFD modelling and experimental work will be presented identifying the strengths and weaknesses of each of the tools.
