Book Description
Dans ce livre, nous étudions les phénomènes, mécanismes et processus hydrologiques continentaux les plus universels qui relèvent des lois de la nature, elles-mêmes universelles. Cela en cinq parties : 1) Le cycle de l'eau en tant que système hydrologique universel; 2) Le climat en tant que moteur du cycle, moteur à régime saisonnier plus ou moins aléatoire; 3) Le bassin-versant portion d'espace dans laquelle s'organise le déroulement de la phase continentale du cycle de l'eau, unité en tant que sous-système, mais unité complexe géographiquement, stable à l'échelle d'un cycle ou à court terme, variable à l'échelle historique; 4) L'écoulement, avec ses débits, réponse du bassin versant aux aléas météorologiques; et 5) Le régime d'écoulement, réponse du bassin aux données climatiques.

Book Description
Au cœur des problématiques environnementales, l’eau est une ressource parfois très rare dont les besoins sont en constante augmentation face à l’accroissement de la population mondiale et de son niveau de vie. Comment prévoir la surabondance de l’eau en période de crues ou d’inondations ? Crues rapides comme celles qui résultent de deux ou trois jours d’averses cévenoles, ou crues lentes résultant d’une année ou plus de précipitations plus abondantes que d’ordinaire dans le cas de la Somme ou de la Seine ? Comment assurer la qualité de l’eau potable et minimiser les risques de pollution des nappes sans connaître les processus d’infiltration de l’eau dans le sol ? Comment estimer les effets d’un reboisement sur les ressources en eau si l’on ne tient pas compte des processus d’interception de l’eau par la végétation ? Fondé sur une approche essentiellement naturaliste, ce manuel permet de comprendre et de quantifier le cheminement de l’eau, de son apport au sol sous forme de précipitations à son retour dans l’atmosphère à l’état gazeux par le processus d’évaporation. Cette connaissance indispensable permet de prévenir et de gérer les risques pouvant résulter des aménagements humains. Cet ouvrage de référence, qui porte principalement sur les milieux tempérés, est destiné aux étudiants de géographie et de géologie de surface, et plus largement à l’ensemble des acteurs de l’environnement. Claude COSANDEY est géographe, directrice de recherches émérite au CNRS. Mark ROBINSON est Principal Scientific Officer au Centre pour l’écologie et l’hydrologie de Wallingford. Ses travaux portent sur l’hydrologie forestière, le drainage et l’évolution à long terme des bassins versants.

Book Description
L'eau ressortit à de multiples disciplines : climatologie, hydrologie, glaciologie, géomorphologie, biogéographie...; aussi son étude est-elle rarement menée pour elle-même. L'ouvrage de Jean-Pierre Vigneau se veut une géographie (physique) de l'eau. Il est donc conçu comme un parcours transversal, organisé selon le continuum du cycle. L'angle choisi est celui du mouvement. L'analyse porte sur les échanges entre les grands réservoirs de la planète et sur les transferts au sein de trois d'entre eux. Ainsi, l'eau n'est ni reléguée au rang d'élément, ni réduite à un rôle d'agent; elle est remise à sa place d'acteur déterminant du fonctionnement naturel, de thème central de la géographie.

Book Description
This book gives a comprehensive presentation of our present understanding of the Earth's Hydrological cycle and the problems, consequences and impacts that go with this topic. Water is a central component in the Earth's system. It is indispensable for life on Earth in its present form and influences virtually every aspect of our planet's life support system. On relatively short time scales, atmospheric water vapor interacts with the atmospheric circulation and is crucial in forming the Earth's climate zones. Water vapor is the most powerful of the greenhouse gases and serves to enhance the tropospheric temperature. The dominant part of available water on Earth resides in the oceans. Parts are locked up in the land ice on Greenland and Antarctica and a smaller part is estimated to exist as groundwater. If all the ice over the land and all the glaciers were to melt, the sea level would rise by some 80 m. In comparison, the total amount of water vapor in the atmosphere is small; it amounts to ~ 25 kg/m2, or the equivalent of 25 mm water for each column of air. Yet atmospheric water vapor is crucial for the Earth’s energy balance. The book gives an up to date presentation of the present knowledge.

Book Description
The amount of water on Earth today is the same amount that will be on it tomorrow! How is this possible? Through understandable descriptions and helpful graphic organizers, readers are introduced to the water cycle. Full-color photographs and fun fact boxes supplement the main content, which takes readers through the cycle step by step. Basic science concepts such as precipitation, evaporation, and groundwater are explored, and readers are presented with an overview of water conservation they can easily implement in their homes.

Book Description
Water is an extremely important factor in global environmental change. Water influences the processes causing change. The human and economic consequences of changes in the water system can be very significant. The aim of this NATO Advanced Study Institute was to present a state-of-the-art assessment of the role of water in global change, ranging from a consideration of atmospheric processes to the social and political impacts of changes in water resources. Many initiatives have recently been developed, such as international conferences and research programmes in particular themes, but there was still a need for information from these diverse activities to be brought together. One of the aims of the ASI was to encourage cross-fertilization between the various disciplines looking at water in the global system. This book contains the expanded written versions of the lectures presented during the AS! held in Italy in May/June 1994. It falls into two basic parts. The first twelve chapters cover the role of water in the climate system and climate modelling. Various areas of the water balance including global budgets, the effect of each element of the water balance on regional and global climates, and procedures used to model hydrological processes at all scales are discussed. Precipitation, ice, lake, groundwater, land surface and atmospheric considerations are included together with hydrological process linkage to climate models. Ocean effects were not covered as they were considered to be outside the scope of this particular AS!.

Book Description
Originally published in this form in 1971, the content of this book was originally part of a larger composite volume ‘Water, Earth and Man’ (1969) which provided a synthesis of hydrology, geomorphology and socio-economic geography. This volume brings together the systematic theme of spatial aspects of the interactions between water occurrence and human activity.

Book Description
This title focuses on the evolution of the modeling process and on new research perspectives in theoretical and applied geography, as well as spatial planning. In the last 50 years, the achievements of spatial analysis models opened the way to a new understanding of the relationship between society and geographical space. In this book, these models are confronted by the real conditions of territorial prospect, regional dynamism, cultural policy, HMO, and spatial segregation. This confrontation takes into account the instability of social behavior and the permanence of partial determinist trajectories.
