Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in developing countries, industrialized countries continue to struggle with pollution problems as well. Water is typically referred to as polluted when it is impaired by anthropogenic contaminants and either does not support a human use, such as drinking water, and/or undergoes a marked shift in its ability to support its constituent biotic communities, such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause major changes in water quality and the ecological status of water. Most water pollutants are eventually carried by rivers into the oceans.

Hydroclimatology provides a systematic structure for analysing how the climate system causes time and space variations (both global and local) in the hydrologic cycle. Changes in the relationship between the climate system and the hydrologic cycle underlie floods, drought and possible future influences of global warming on water resources. Land-based data, satellite data, and computer models contribute to our understanding of the complex time and space variations of physical processes shared by the climate system and the hydrologic cycle. Blending key information from the fields of climatology and hydrology - which are not often found in a single volume - this is an ideal textbook for students in atmospheric science, hydrology, Earth and environmental science, geography, and environmental engineering. It is also a useful reference for academic researchers in these fields.

L'air et l'eau, chacun connaît ; nous savons que sans ces deux fluides, notre vie serait impossible sur Terre. Et après ? Que savons-nous sur eux ? Depuis quelques années, des événements graves se multiplient : cyclones, tornades, tsunamis, inondations… mais sait-on comment cela fonctionne ? Le livre apporte les réponses à ces questions. Tout d'abord, on considère l'air et l'eau dans des situations dites " à l'équilibre ", c'est-à-dire pour lesquelles on se pose d'ordinaire peu de questions. Puis on aborde les phénomènes dynamiques aux diverses échelles. Le parti pris est de décrire avant d'expliquer. L'ouvrage se termine par la présentation de constructions humaines (barrages, ports…) destinées à domestiquer et utiliser l'eau à notre avantage Le lecteur se voit proposer une promenade à diverses échelles, des alizés aux nuages, du Gulf Stream aux vaguelettes. Ainsi il découvre et comprend de façon intuitive les phénomènes. Ceux qui désirent des démonstrations plus physiques et mathématiques iront visiter le site web en libre accès du pap-ebook et auront besoin d'un niveau scientifique supérieur. La majorité des lecteurs effectuera une promenade sur Terre avec nos deux fluides fétiches grâce à un livre remarquablement illustré avec ses index, glossaire, annexe, et aussi avec les films du site web. Ce livre restera un incontournable de la bibliothèque que l'on pourra conserver pour le consulter à nouveau, et l'utiliser comme base de toute recherche sur l'air et l'eau.

Within the discipline of environmental sciences, the stable-isotope methodology is being increasingly used, especially in the study of the water cycle and of paleo-climatology. This book reviews the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionalism, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. It focuses on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites

This collected work reports on the state of the art of hydrological model simulation, as well as the methods for satellite-based rainfall estimation. Mainly addressed to scientists and researchers, the contributions have the structure of a standard paper appearing in most cited hydrological, atmospheric and climate journals. Several already-known hydrological models and a few novel ones are presented, as well as the satellite-based precipitation techniques. As the field of hydrologic modeling is experiencing rapid development and transition to application of distributed models, many challenges including overcoming the requirements of compatible observations of inputs and outputs are addressed. The many contributing authors, who are well established in this field, provide readers with a timely overview of the ongoing research on these topics. The level of interest and active involvement in the discussions clearly demonstrate the importance the scientific community places on challenges related to the coupling of atmospheric and hydrologic models.
