Groundwater Modelling in Arid and Semi-Arid Areas


Book Description

Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.




Water-Soil-Vegetation Nexus and Climate Change


Book Description

Water-Soil-Vegetation Nexus and Climate Change presents a broad overview of the research needs and approaches regarding water-soil-vegetation nexus and climate change. It includes chapters discussing water budget and factors that affect hydrologic processes such as precipitation, runoff, infiltration, evapotranspiration, soil water, and groundwater, in addition to a focus on consumptive (e.g., domestic and irrigation) and non-consumptive (e.g., eco-environmental) water uses, and water shortage. Throughout Water-Soil-Vegetation Nexus and Climate Change chapters specifically deal with the fundamental principles and also case studies, applications, and decision support tools, that can be usable for developing practical management measures in sustaining our eco-environment and society by maintaining an optimal water-soil-vegetation equilibrium. Written with water resources students and professors in mind, this book will provide the reader with further knowledge on the water-soil-vegetation nexus and its connection to climate change. - Includes both principles and applications, providing the reader with options for both application types as needed - Emphasizes the nexuses rather than individual processes, allowing the reader to understand the whole picture - Presents case studies and decision support tools that can be used for developing practical management measures in changing climate







Land Surface Evaporation


Book Description

General circulation model (GCM) experiments in the late 1970's indicated that the climate is sensitive to variations in evaporation at the land surface. Thus, in the context of climate modeling, it became important to develop techniques which would realistically estimate the evaporation flux on land. Land Surface Evaporation: Measurement and Parameterization discusses strategies for the use of experimental data in developing and testing parameterization schemes of the evaporation flux in GCM's. The book reviews state-of-the-art techniques, such as remote sensing, which measure evaporation fluxes over continental surfaces. It evaluates their relevance with respect to the various spatial and temporal scales of interest. This book will provide researchers in climatology, meteorology, hydrology and water management, and remote sensing with a thorough overview of current research in land surface evaporation. It will also give young scientists insight into surface processes.




Dryland Ecohydrology


Book Description

Ecohydrology emerges as a new field of research aiming at furthering our understanding of the earth system through the study of the interactions between the water cycle and vegetation. By combining the analysis of biotic and abiotic components of terrestrial ecosystems, this volume provides a synthesis of material on arid and semiarid landscapes, which is currently spread in a number of books and journal articles. The focus on water-limited ecosystems is motivated by their high sensitivity to daily, seasonal, and decadal perturbations in water availability, and by the ecologic, climatic, and economic significance of most of the drylands around the world. Conceived as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. The chapters collected in this book have been contributed by authors with different expertise, who work in several arid areas around the World. They describe the various interactions among the biological and physical dynamics in dryland ecosystems, starting from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns.




International Climate Protection


Book Description

This book explains the current climate protection processes and technologies, and informs the readers of the limiting factors and opportunities for future development. It represents the highest level of knowledge from leading scientists all over the world. Original high quality figures maximize understanding of the text. The book also introduces a new concept (climotographic), which provides a well pronounced solution to climate protection that is easily understandable for all levels of readers.







Banded Vegetation Patterning in Arid and Semiarid Environments


Book Description

Aerial photography has revealed the striking, widespread phenomenon of repeating patterns of vegetation in more arid areas of the world. Two interdependent phases, bands of dense and sparse vegetation, alternate in the landscape. This volume synthesizes half a century's accumulated knowledge of both theoretical and applied landscape function from a variety of these regions. It covers structure, dynamics, and methods of study, as well as disturbances to these landscapes and relevant management issues. Various chapters discuss the role of modeling in answering questions about the origins and complex processes of banded landscapes.
