Abstract

For detecting chaotic features in fluvial mixing processes laboratory flowwith complex geometry was investigated using surface ParticleTrackingVelocimetry (PTV) technique. In the reconstructed velocity field particles were deployed and tracked numerically in a Lagrangian way. Calculating some appropriate parameters (e.g. flushing time, finite-size Lyapunov exponent) originating from chaos theory, it has been possible to give a novel, more detailed picture on the mixing in groyne zones, including the separation of sub-regions characterized with different mixing efficiency.
