From where--and what--does water come? How did it become the key to life in the universe? Water from Heaven presents a state-of-the-art portrait of the science of water, recounting how the oxygen needed to form H2O originated in the nuclear reactions in the interiors of stars, asking whether microcomets may be replenishing our world's oceans, and explaining how the Moon and planets set ice-age rhythms by way of slight variations in Earth's orbit and rotation. The book then takes the measure of water today in all its states, solid and gaseous as well as liquid.

The fresh water supplies of the Earth are finite and as the world's population continues to grow humanity's thirst for this water seems unquenchable. Intense pressure is being exerted upon freshwater resources and a lack of adequate clean water is seen as one of the most serious global problems for the 21st century. Indeed it has been said that the next war will be fought over water, not oil. Human health and the health of supporting ecosystems increasingly depends upon our ability to find, control, manage and understand water.

The specialist contributors to Geomorphological Techniques have thoroughly augmented and updated their original, authoritative coverage with critical evaluations of major recent developments in this field. A new chapter on neotectonics reflects the impact of developments in tectonic theory, and heavily revised sections deal with advances in remote sensing, image analysis, radiometric dating, geomorphometry, data loggers, radioactive tracers, and the determination of pore water pressure and the rates of denudation.

The Hydrology of the UK assesses the changing hydrology of the UK, focusing on key issues that affect the fundamental hydrological processes and have important implications for water resource management, flood risk and environmental quality. The bookis divided into 3 sections: Section 1 examines the causes of change to the hydrology of the UK, including the impact of climate change, land use and geomorphological change, and dam construction. Section 2 assesses the effects of these pressures on UK rivers, goundwater, lakes, ponds, reservoirs and wetlands, looking at water quality,...

The book is divided into three sections covering: the causes of change to the hydrology of the UK, including the impact of climate change, land use and geomorphological change and dam construction; the effects of these pressures on UK rivers, goundwater, lakes, ponds, reservoirs and wetlands, looking at water quality, degradation, pollution and protection; and the...

Efficient and equitable water, wastewater and stormwater management for the megacities is becoming an increasingly complex task. The special issue will focus on water management in its totality for megacities, including their technical, social, economic, legal, institutional and environmental dimensions through a series of specially invited case studies from different megacities of the world.

At present, around one out of two of the earth's 6.3 billion people live in urban areas. Each year, the world population grows by around 80 millions. Practically all of this growth is...

By 2050, the demand for water to sustain world agriculture will increase by seventy-five per cent in order to feed an estimated nine billion inhabitants. Increased amounts of water will be required for irrigation and for industrial and domestic use. Natural ecosystems will be threatened by the expansion of agricultural land and by a reduction in water availability, while climate change will exacerbate the situation. Management of available resources, particularly groundwater, will become more critical and aquifers will need to be managed for the benefit of all.

These selected...

Groundwater abstraction plays a very important part in water supplies throughout the world. Yet too many wells and boreholes operate inefficiently or are abondoned.

Presents readers with an overview of lake management problems and the tools that can be applied to solve probelms. Lake management tools are presented in detail, including environmental technological methods, ecotechnological methods and the application of models to assess the best management strategy.

Sediments are a natural part of aquatic systems and they are essential for the hydrological, geomorphological and ecological functioning of those systems. For society they are important and represent an important resource. However, due to the ever increasing use of river catchments, sediments need to be managed in a balanced and sustainable way. Sediment Management at the River Basin Scale reviews some of the key requirements and challenges facing scientists, river basin managers, and policy makers for sustainable sediment management at the river basin scale, and puts forward important...

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 varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal...

Adsorption of Metals by Geomedia II serves as a needed resource for this topic which has received much attention during the past 25 years. The book provides an in-depth review of the field, followed by numerous chapters that document the current status of adsorption research for a variety of metals by geomedia ranging from individual minerals to sediments and soils. Adsorption mechanisms are detailed and precipitation is presented as a distinct sorption process. Virtually all factors affecting the extent of metal adsorption are examined, including the effects of selected anions,...

Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals.

With considerable interest in global change, this topical book provides a general overview of global paleohydrology. The first section provides a global review of the field by exploring real world hydrological scenarios during past environmental changes over extensive areas of Europe, America, Africa, Asia and Australasia. This is followed by an up-to-date review of the key methodologies of fluvial palaeohydrology and the hydrological methods for palaeohydrological construction

New exploration tools and techniques for a breakthrough paradigm of regional groundwater occurrence
Fresh water is undoubtedly our most precious resource aside from the air we breathe, and the only commodity whose cost has steadily risen over time. At the same time, our understanding of the origins, pathways, and recharge mechanisms of the earth's most valuable "economic" mineral-groundwater-remains in the nineteenth century. It is ironic that this scientific anachronism is contributing to a global shortage of available fresh water supplies while oil, gas, and mineral discoveries have...
