Abstract: The characteristics of three-dimensionality, anisotropy and non homogeneity of turbulence, that are present in the flow of hydraulic energy dissipators prevent an analytica1 study of this problem. In this case hydraulic modelling is the fundamental tool for studying the pressure field in those structures. The practical difficulties in this kind of studies, like detection, recording and analysis of pressures, instrumentation checking and scale effects, among others, prevent us from obtaining better knowledge of the problem. This paper suggests a solution for those practical difficulties, through an experimental and numerical methodo1ogy. The Experimental Methodology enables presssures to be recorded at different points of the structure in study and the Numerical Methodology enables us to correctly acquire and analyse the pressure field. This analysis is performed in the time domain and frequency domain. The first results of the application of this methodology in the case of freefalling jet at arc dams into a plunge pool, are presented.
