The concern over groundwater contamination has focused attention on the processes that influence the fate of chemicals in soil water systems. A major concern of groundwater contamination is the passage of these chemcials through the unsaturated zone and the relatively thin cover layers overlying the aquifers. Pollution due to diffuse sources is probably the most difficult to model. This is because the loads are usually non-homogeneous and they are also governed by spatially and temporally non-homogeneous, but dynamic, processes of chemical and biochemical phenomena.In this book, the estimation techniques and transfer functions of required input data from existing databases in geographic information systems are provided. Spatially variable input data, such as the type of soil, hydrological conditions, intensity of land use and atmospheric deposit of pollutants, are derived from basic land and climate characteristics. A model for the evaluation of land use and water management is also described. In addition, examples of field and regional studies on water management and policy analysis are provided.

Orthopedic Trauma Care is a valuable resource for optimizing the care of orthopedic trauma patients. The book begins by presenting classification, wound and fracture healing, principles of fracture treatment, and information on the care of polytrauma patients. It closes with details on specific injuries and common complications and syndromes secondary to traumatic injuries.
"The author opens a powerful dialogue between agricultural history on the one hand and environmental history on the other... a brilliant and provocative synthesis of a thousand years of coastal farming." Tim Soens, University of Antwerp, Belgium. The fascinating story of how the North Sea coast has been farmed is ever changing. Long before the industrial revolution, the inhospitable fens and marshes of the low-lying coastal wetlands on both sides of the Sea had been transformed into one of the most productive agricultural regions in Europe. Agriculture in the coastlands reached its apogee during the eighteenth and nineteenth centuries, as is witnessed by the many impressive farm buildings established then. However, more recently, it has become clear that lowland farming and even the physical existence of the lowlands are in jeopardy, owing to rising sea levels and problems of drainage. This book offers a history of farming and water management on the North Sea coast, assessing the forces driving - and inhibiting - agricultural progress more broadly. It examines the ways in which farmers in the past dealt with the two main constraints on their decision-making: the natural environment and the human environment of institutional rules and customs regulating behaviour. It looks in particular at how setbacks were overcome, and how farming practices were improved which then raised the money with which to finance the maintenance of dykes, canals, and sluices.
