Horizontal dispersion by tidal and residual currents is discussed in terms of two different
mechanisms, viz. a “cascade” of shear-dispersion processes and “Lagrangian chaos”. In the …

This book is an outgrowth of research contributions and teaching experiences by all the
authors in applying modern fluid mechanics to problems of pollutant transport and mixing in …

The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal
mixing and salt intrusion. The shape of an alluvial estuary is characterised by exponentially …

Transport phenomena are among the most important processes in natural systems.
Chemical compounds, the constituents of biogeochemical systems, are in continual motion …

The paper examines how a passive contaminant disperses along the axis of a tube in which
the flow is driven by a longitudinal pressure gradient varying harmonically with time. This …

The homogenization of a passive 'tracer'in a flow with closed mean streamlines occurs in
two stages: first, a rapid phase dominated by shear-augmented diffusion over a time≈ P1/3 …

While major oil spills are rare, oil slicks can have disastrous environmental and economic
consequences. This book summarizes research on the use of chemical dispersants: their …

Three Markovian particle models are reviewed, providing a hierarchy of increasingly
detailed descriptions of particle motion and dispersion. Model 1 assumes that the scales of …

An analysis of a two-dimensional tidal model of the Wadden Sea reveals Lagrangian chaos
in the trajectories of water parcels. The associated chaotic stirring results from the transverse …
