Studies of sediments have been increasingly high lighted internationally because of their negative infl uence on the quality of the aquatic environment. The problems caused by these sediments may be physical, whereby they can lead to the aggradation of water bodies and the subsequent obstruction of engineered structures, or they may be chemical upon the release of pollutants previously transported in association with them. To mitigate these impacts, sedimentological studies need to be structured care fully to meet specific needs. This volume therefore aims to explore sediments logically, from their origins, impacts on the aquatic environment to their collection in the field and subsequent analytical methodologies, in order to provide a thorough examination of one of the symptoms of anthropogenic impact on the environment.
There are therefore various themes that run through the book:
establishment of the sources of sediments, andhow they can be characterized and traced;- transportation of sediments, their pollutant burden in the environment and their final destination;
their potential to impact negatively on receivingwaters and biota;the production of useful and accurate data for usein models and management strategies to mitigate such impacts.
The chapters are written by international experts in their fields and provide in – depth considerations of current and topical research in the fi eld of aqueous sedimentology. Thus, Chapters 1 and 2 critically explore the limitations of approaches used in the collection of suspended and bed sediment samples in order to address the perennial problem of ensuring quality data are produced based on the collection of quality samples. They cover traditional techniques of extracting physical samples and advances in the various means of remotely monitoring sediment concentration.
Chapter 3 leads on from the collection of sediment samples in Chapters 1 and 2 by an in – depth consideration of sediment characteristics and characterisation. It therefore details the behaviour of particles in water, the forces involved in both holding them together and forcing them apart as well as the energy required in such processes. Techniques such as light scattering, X – ray diffraction and electron microscopy are critically examined and nuclear magnetic resonance and infrared spectroscopy bring the subject right up to date allowing the reactivity of particulates to be assessed and their ability to interact with the environment to be better understood.
