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.

Experimental and numerical analysis of velocities in plunge pools of free falling spillways
Turbulence constitutes one of the principal mechanisms of energy dissipation in plunge pools. In falling jets and in
dissipation basins appear high turbulence and aeration phenomena that cannot be correctly studied by the classical
Given this problem, and based on the different experimental results obtained in the study of free falling jets, researchers
are characterizing such flows in the Laboratory of the Universidad Polit¨¦cnica de Cartagena (Spain). Velocities, pressures
and air entrainment rates are being obtained and analyzed.
The methodology of computational fluid dynamics (CFD) can simulate the interaction between different fluids, such as the
two-phase water-air flows case. The CFD codes are based on the numerical solution of the Reynolds-averaged Navier¨C
Stokes equations (RANS), together with turbulence models with different degrees of complexity. In this way, the results
obtained in laboratory are compared with the complementary numerical model.
