Climate and Land Surface Changes in Hydrology


Book Description

Focuses on field-based and modelling studies addressing the sensitivity of hydrological and hydrometeorological fluxes of the coupled landatmosphere system to climate and land-use change at local, regional and global scales. The volume includes significant model-based studies evaluating methodologies and impacts of using climate and weather prediction data including downscaling and uncertainty analyses. Hydrological sensitivity and impacts due to spatial and temporal land-use and land-cover variability are reported for a wide variety of environmental settings. Observational and model-based investigations assess the significance of land cover and hydrological dynamics for the development of land surface heat fluxes and regional climate. Several empirical hydroclimatological studies, some from remote and data-scarce regions, and others using long-term multi-variable time series data or Earth Observations to evaluate temporal and spatial variability in precipitation, evapotranspiration and hydrological predictions, are included. The International Association of Hydrological Sciences is the world's premier member-based organization promoting the study and practice of Hydrology. Our books are authored, edited and produced at the highest level of quality, with the most current and thorough research. Our publications and our work advance the science and the professional practice of Hydrology in a variety of Science and Engineering fields around the world.




Forests, Climate, and Hydrology


Book Description

This book representing the research efforts of a dozen hydrologists and climatologists from around the world, grew out of the strongly felt need in the scientific community for an objetive and quantitative assessment of the effects of deforestation or reforestation on climate and hydrology and the regional extent of these effects. Of particular note in this volume, considerable attention is directed to improvements in experimental method and the collection of necessary data and in the application of computer models of atmospheric circulation for the simulation of climate effects of vegetation change.

Vegetation, Water, Humans and the Climate


Book Description

A state-of-the-art overview of the influence of terrestrial vegetation and soils within the Earth system. The text deals especially with interactions between the terrestrial biosphere and the atmosphere via the hydrological cycle and their interlinkage with anthropogenic activities. Measurements gathered in integrated field experiments in the Sahel, the Amazon, North America and South-east Asia confirm the importance of these interactions. Observations are complemented by modelling studies, including regional models that simulate flows and transport in river catchments, coupled land-cover and regional climate systems, and Earth-system and global circulation models. Water, nutrient and sediment fluxes in river basins are also discussed and are shown to be highly impacted and regulated by humans through land use, pollution and river engineering. Finally, the book discusses environmental vulnerability and methodologies for assessing the risks associated with regional and global climatic and environmental variability and change. The results reported in this book are based on the research work of many individual scientists and teams around the world associated with the objectives of the IGBP-BAHC and WCRP-GEWEX international research programmes.




Landscape Dynamics, Soils and Hydrological Processes in Varied Climates


Book Description

The book presents the processes governing the dynamics of landscapes, soils and sediments, water and energy under different climatic regions using studies conducted in varied climatic zones including arid, semi-arid, humid and wet regions. The spatiotemporal availability of the processes and fluxes and their linkage to the environment, land, soil and water management are presented at various scales. Spatial scales including laboratory, field, watershed, river basin and regions are represented. The effect of tillage operations and land management on soil physical characteristics and soil moisture is discussed. The book has 35 chapters in seven sections: 1) Landscape and Land Cover Dynamics, 2) Rainfall-Runoff Processes, 3) Floods and Hydrological Processes 4) Groundwater Flow and Aquifer Management, 5) Sediment Dynamics and Soil Management, 6) Climate change impact on vegetation, sediment and water dynamics, and 7) Water and Watershed Management.

Climatic Change: Implications for the Hydrological Cycle and for Water Management


Book Description

year simulations in order to separate noise in the system from the climate change signal. Several contributing papers focused on case studies using Regional Climate Models (RCMs) linked to hydrological models, applied to the analysis of runoff under conditions of convective activity and extreme precipitation, in regions of complex topography, or stakeholder-driven investigations such as water runoff simulations in Quebec undertaken for a major utility. Thorough analyses of GCM results for the Century were reported at the Workshop, in order to illustrate the improvements in model results which have taken place in recent years, and the increasing confidence with which the models can be used for projecting climatic change in coming decades. However, there is still much room for improvement; there is also a need to address more fully the manner in which climate and impacts models (e. g. , hydrological models) can be linked, in terms of consistency and the overlap between different scales, the underlying physical assumptions, and the parameterizations used. Session 2 was devoted to the two extremes of water resources, namely floods and droughts, the focus here being to identify the climate change component in river floods. These have significant economic implications, as was shown by several scientists from Western and Central Europe. Many long time series have been studied worldwide with the aim of detection of nonstationarities, yet there is no conclusive evidence of climate-related changes in flow records, in general.
