Description :
This paper presents results from an experimental study in the Leeds Experimental Basin where detailed three-dimensional (3D) velocity measurements were obtained at a total of 11 cross-sections through 2 idealized, geometrically symmetrical, bifurcation flume models. The aims of the paper are to identify and to detail the partitioning of fluid, characterize the flow structures through the bifurcation model and to ascertain the key controls on the generation of flow structures at, and downstream of, the bifurcation.
