Sediment Transport Processes and their Modelling Applications is a book which covers a
wide range of topics. The effective management of many aquatic environments, requires a
detailed understanding of sediment dynamics. This has both environmental and economic
implications, especially where there is any anthropogenic involvement. Numerical models
are often the tool used for predicting the transport and fate of sediment movement in these
situations, as they can estimate the various spatial and temporal fluxes.
The search for oil occurs in geological sediments, as opposed to volcanic rocks. Several
processes are involved in the creation of sediments. First, the inland continental volcanic rock is
continuously being weakened and eroded by weathering processes (mechanical (through water,
ice and wind) and chemical erosion). Secondly and simultaneously, the eroded material is being
transported by water, ice and wind and gradually the material may be broken down into smaller
pieces (from boulders to gravel, to sand, to silt and finally to clay).
Estuaries are areas of high productivity, crucial in the life histories of many fish,
invertebrates, and birds, for example, and the sustainability of estuarine biodiversity
is vital to the ecological and economic health of coastal regions. On the other
hand, estuarine ecosystems are exposed to toxic anthropogenic effluents transported
by rivers from remote and nearby conurbations and industrial and agricultural concerns.
The living organism
which will be deeply affected are shredders, which feed on coarse sedimentary detritus, and
collector-gatherers, which feed on fine sedimentary detritus, were the macroinvertebrate
functional feeding groups are most adversely affected. Furthermore, during the industrial
process, high amount of hydrofluoric acid (HF) are used to separate different sandy
materials which are subsequently used for manufacturing glass at industrial plants.
Therefore, high concentration of fluoride ion and suspended inorganic matter discharged by
the industrial into the study site....
