Bøger i Water Resources Monograph serien

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 15. Here is your state-of-the-art guidebook through soil infiltration theory in response to hydrologic problems. By focusing on the theoretical basis of physically based infiltration functions and their application, Infiltration Theory for Hydrologic Applications presents an in-depth review of current issues and concerns. For scientists wishing concise and robust equations that can be applied in models for a variety of objectives.

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 16. From the local to the global scale, water use and sustainability are issues of pressing importance. Never before has water science needed to inform water policy so much, and never before have we seen how challenging it is to advance that relationship. How rapidly is the demand for water growing? What climate- or pollution-imposed limits to water supplies exist, and how can we best manage them? Will privatization benefit water management, resource development, and the environment?How can science work more closely with the policy and engineering communities to perfect knowledge-based water planning? Water: Science, Policy, and Management discusses these issues, and more. Scientists in water research and geography, water policy experts, water managers and engineers, lawyers grappling with water issues, and environmentalists concerned with the state of water internationally will find this book a significant resource now and in the coming years.

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 17. Nonaqueous phase liquids (NAPLs) are frequently found as soil and groundwater contaminants. Highly toxic even in small volumes, NAPLs can pose a threat to human health and damage surface and subsurface ecosystems. In this book, we clarify the complex phenomena of NAPL migration and offer insight into the behavior of NAPLs at sites undergoing monitoring and remediation. Contents include discussion on: Principles of NAPL behavior in the subsurface, including flow, transfer of components to water and gas phases, and transport Migration and distribution Site characterization and monitoring Remediation methods, including hydraulic removal, pump and treat, and soil vapor extraction Further discussion on gaps in our understanding of NAPLs at the field scale along with a thorough tutorial approach and supplemental CD, make this book an important guide and resource for practicing engineers and scientists, risk assessment professionals, teachers, and students.

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 18. Landslides are a constant in shaping our landscape. Whether by large episodic, or smaller chronic, mass movements, our mountains, hills, valleys, rivers, and streams bear evidence of change from landslides. Combined with anthropogenic factors, especially the development and settlement of unstable terrain, landslides (as natural processes) have become natural disasters. This book charts our understanding of landslide processes, prediction methods, and related land use issues. How and where do landslides initiate? What are the human and economic consequences? What hazard assessment and prediction methods are available, and how well do they work? How does land use, from timber harvesting and road building to urban and industrial development, affect landslide distribution in time and space? And what is the effect of land use and climate change on landslides? This book responds to such questions with: - Synopses of how various land uses and management activities influence landslide behavior - Analyses of earth surface processes that affect landslide frequency and extent - Examples of prediction techniques and methods of landslide hazard assessment, including scales of application - Discussion of landslide types and related costs and damages Those who study landslides, and those who deal with landslides, from onset to after-effects--including researchers, engineers, land managers, educators, students, and policy makers--will find this work a benchmark reference, now and for years to come.
