Developments in the modelling of sediment transport in rivers and
the interactions with the river--bed have been remarkable over the
last two decades. This progress has increased the understanding of
the nature of turbulence, and the ability to replicate
mathematically simple flow--particle interactions which can be
observed experimentally. In addition, quite elegant models of
stratigraphic complexes have evolved because of the growing
computational power available to scientists. As always, additional
knowledge has raised even more intriguing questions and the quest
for explanation of phenomena has led to increased specialisation.
Therefore, there are few fluid dynamicists or sedimentologists who
can successfully span the two disciplines. The intention of this
book is to assist various specialists on keeping abreast of current
developments in related areas. The book initially focuses on
hydrodynamics of turbulent flow, followed by basic two and
three--dimensional flow through straight and curved channels and
the flow over bed topography. This is then followed by a
consideration of initial motion, sediment transport and particle
sorting. The potential for modelling fluidsediment interactions is
provided at the end of the first section. Linking chapters then
follow, considering the preservation potential of fluvial bedforms
in the stratigraphic record and the basic variety of channel
morphology recognised in sedimentary studies. Subsequent chapters
consider reconstructing hydraulic process and fluvial morphology
from stratigraphy; the influence of bedform and depositional
controls on packing of economically important sedimentary rocks;
and recent advances in modelling subsurface fluvial stratigraphy. A
final chapter provides a brief view of future perspectives. The
objective of this volume is to review recent advances made by
geologists and hydrodynamicists in an accessible manner and to
promote an increased and fruitful dialogue between sedimentary
geologists, geomorphologists and hydrodynamicists.
