Book Description
Hydrology is vital to human civilisations as well as to natural ecosystems, yet it has only emerged as a distinct scientific discipline during the last 50 years or so. This book reviews the development of modern hydrology primarily through the experiences of the multidisciplinary team of scientists and engineers at Wallingford, near Oxford, who have been at the forefront of many of the developments in UK hydrological research. These topics include: • The development of basic understanding through the collection of data with specialised instrumentation in experimental basins • The study of extreme flows – both floods and droughts • The role moisture in the soil • Studies of the processes controlling evaporation • Water resource studies • Modelling and prediction of the extremes of flow improved • Understanding of water quality issues • A widening recognition of the importance of an ecosystem approach • Meeting the challenges of climate change, • Data handling • Future developments in hydrology and the pressures which generate them. Readership: hydrologists in both academia and a wide range of applied fields such as civil engineering, meteorology, geography and physics, as well as advanced students in earth science, environmental science and physical geography programmes worldwide.
Global Environmental Change and Land Use
Author: Han HaarmanPublisher: Springer Science & Business Media
ISBN: 9401703353
Category : Science
Languages : en
Pages : 228
Book Description
The interaction between environmental change and human activities is com plex, requiring the concepts and tools of a number of disciplines for its effective analysis. Land-use and land-cover change has only recently become a topic susceptible to scientific research, as these concepts and tools have been devel oped and made available. Rooted in a broad community concemed with global change, systematic research has begun into land-use systems at different scales and interactions, and their links with global cyc1es of water, nitrogen and carbon are being explored. Partly based on research initiated by the Dutch National Research Programme on Global Air PolIution and Climate Change (NRP), this book touches upon various land-use and land-cover issues in relation to global environmental change. In addition to the biogeochemical cyc1es, land as a car rier for functions of economic activities, food and fibre production and energy production via biomass are discussed. Crucial in studying land use is human behaviour and man-environment interaction at different scales. Land-use and land-cover change is an important contrlbutor of greenhouse gasses as these activities directly interfere with the carbon, nitrogen and water cyc1es. These cyc1es are connected through numerous feedback loops. The interface of land-use and c1imate is essentially determined by the interaction of man and the environment. Man uses land primarily to produce food; a relatively small area is needed for urban development.
Journal of Hydrometeorology

Book Description
Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 3. Land surface hydrology integrates various physical, chemical and biological processes that occur above, on, and below the surface of the Earth. As a result, it is critical to accurately account for land surface processes within predictive models of hydrology, meteorology, and climate. One of our main difficulties, however, concerns the broad range of spatial and temporal scales that characterize land surface hydrological processes. For example, we determine infiltration by pore scale physics, while soil hydraulic conductivity remains a field scale property. Photosynthesis, respiration, and transpiration occur at the leaf scale. Runoff is a catchment scale process, and the variability of groundwater storage is a regional scale issue. Turbulence in land-atmosphere exchanges of heat, moisture, and momentum occur on the order of seconds to minutes, while variations in land surface and air temperatures occur much more gradually: on the order of hours. The persistence of floods and droughts is seasonal to annual, and so is the effect of El Nino on regional hydrology. Long-term climate effects occur much more slowly, on the order of years to decades.

Book Description
Sealing up in Hydrology using Remote Sensing Edited by J. B. Stewart Institute of Hydrology, UK E. T. Engman NASA Goddard Space Flight Center, USA R. A. Feddes Wageningen Agricultural University, The Netherlands Y. Kerr Centre d’Etudes Spatiales de la Biosphere, France The most pressing modern environmental problems are considered to affect the entire globe. For example, climate change, deforestation and desertification are all happening on such a large scale that they may affect the sustainability of man’s future. What is needed to address this question quantitatively are more reliable data on large scale land use and land-use change, and their impacts on water resources and climate. The catch is that we are never going to be able to measure directly key hydrological and meteorological variables at enough points on the ground to give adequate description of the large areas (regions and continents) for which information is required. The only way to get this is via large scale modelling and the development of remote sensing techniques. This book brings together the presentations made at a recent workshop by experts, who met to consider the problems of scaling up from local to global spatial scales and from the instantaneous satellite measurements to daily or longer time scales. The authors’ collective views represent the state of the art of their science as seen by an active international remote sensing community, and ground and planetary-based measurement scientists and modellers.

Nile and Grand Ethiopian Renaissance Dam
Author: Assefa M. MelessePublisher: Springer Nature
ISBN: 3030764370
Category : Science
Languages : en
Pages : 525
Book Description
This book is a contribution by the presenters of the 2020 International Conference on the Nile and Grand Ethiopian Renaissance Dam (GERD). The Nile basin is facing unprecedented level of water right challenges after the construction of GERD has begun. Ethiopia, Egypt and Sudan have struggled to narrow their differences on filling and operation of the GERD. The need for science and data-based discussion for a lasting solution is crucial. Historical perspectives, water rights, agreements, failed negotiations, and other topics related to the Nile is covered in this book. The book covers Nile water claims past and present, international transboundary basin cooperation and water sharing, Nile water supply and demand management, Blue Nile/Abbay and Grand Ethiopian Renaissance Dam, land and water degradation and watershed management, emerging threats of the Lakes Region in the Nile Basin, and hydrologic variation and monitoring. This book is beneficial for students, researchers, sociologists, engineers, policy makers, lawyers, water resources and environmental managers and for the people and governments of the Nile Basin.
