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.

On the set-up of experiments on surface pollution influenced vortices

ABSTRACT
The current guidelines for sump design with respect to the transport of floating debris provides only information for a
limited number of sump geometries. Basically, there is a need for a more generic formulation of guidelines with respect to
the transport of (floating) debris. In the research for these new guidelines for transporting debris, free surface vortices are
defined as an governing mechanism for the transport of floating debris. To achieve knowledge on the ability of vortices as
transport mechanism and for the verification of CFD models, experiments in a real scale test facility will be conducted. The
experiments must provide data on the influence of different types of floating debris on the formation of surface vortices, the
transitions between vortices and the transport ability i.e. duration and stability of various types of vortices. An experimental
set-up provides 2D visual data of the surface activity and behavior of floating debris. The set-up also provides data of
pump performance measurement which is presumed to be influenced by air entrainment and pre-rotation.
