The Chernobyl Nuclear Power Plant (NPP) disaster that occurred in Ukraine on April 26, 1986, was one of the most devastating in human history. Using this as a case study, the AGU monograph Groundwater Vulnerability: Chernobyl Nuclear Disaster is devoted to the problem of groundwater vulnerability, where the results of long-term field and modeling investigations of radionuclide transport in soil and groundwater, within the Ukrainian part of the Dnieper River basin (Kyiv region of Ukraine), are discussed. The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater. This volume also includes the evaluation of the effect of preferential and episodic flow on transport of radionuclides toward the aquifers and risk assessment of groundwater vulnerability, which can further assist future researchers in developing remediation technologies for improving drinking water quality. Further, this volume sheds light on the consequences of groundwater contamination from nuclear disasters and assists with assessing the risks associated with contamination and developing effective remediation technologies. Volume highlights include discussions of the following: – Assessment of groundwater vulnerability to contamination from the Chernobyl nuclear disaster – Novel analytical results of the 25-year investigations of groundwater contamination caused by Chernobyl-born radionuclides – The wealth of data on different modes of radioactive transport in the atmosphere, water, and soils, and along the food chains – The hydrogeological and physico-chemical processes and factors in groundwater contaminated zones – The applicability of commonly used methods of the evaluation of groundwater vulnerability – A unique method of fluid dynamics that involves an anomalously fast migration of contaminants through zones of preferential flow from the land surface toward groundwater – Building confidence in the assessment of migration pathways of radionuclides in the biosphere – Assessment and prediction of the consequences of the nuclear accident, which can shed light on protection from global nuclear accidents – Analogue information for different nuclear waste disposal and environmental projects around the world


Seismic Vulnerability of Structures Seismic Vulnerability of Structures

Автор: Philippe Gueguen

Год издания: 

This book is focused on the seismic vulnerability assessment methods, applied to existing buildings, describing several behaviors and new approaches for assessment on a large scale (urban area). It is clear that the majority of urban centers are composed of old buildings, designed according to concepts and rules that are inadequate to the seismic context. How to assess the vulnerability of existing buildings is an essential step to improve the management of seismic risk and its prevention policy. After some key reminders, this book describes seismic vulnerability methods applied to a large number of structures (buildings and bridges) in moderate (France, Switzerland) and strong seismic prone regions (Italy, Greece). Contents 1. Seismic Vulnerability of Existing Buildings: Observational and Mechanical Approaches for Application in Urban Areas, Sergio Lagomarsino and Serena Cattari. 2. Mechanical Methods: Fragility Curves and Pushover Analysis, Caterina Negulescu and Pierre Gehl. 3. Seismic Vulnerability and Loss Assessment for Buildings in Greece, Andreas J. Kappos. 4. Experimental Method: Contribution of Ambient Vibration Recordings to the Vulnerability Assessment, Clotaire Michel and Philippe Gueguen. 5. Numerical Model: Simplified Strategies for Vulnerability Seismic Assessment of Existing Structures, Cedric Desprez, Panagiotis Kotronis and Stephane Grange. 6. Approach Based on the Risk Used in Switzerland, Pierino Lestuzzi. 7. Preliminary Evaluation of the Seismic Vulnerability of Existing Bridges, Denis Davi.

Independent Child Migrations: Insights into Agency, Vulnerability, and Structure. New Directions for Child and Adolescent Development, Number 136 Independent Child Migrations: Insights into Agency, Vulnerability, and Structure. New Directions for Child and Adolescent Development, Number 136

Автор: Orgocka Aida

Год издания: 

Explore the complexities of international independent child migration. This volume gives particular focus to agency and vulnerability as central concepts for understanding the diverse experiences of children who have migrated alone. Combining perspectives from academics and practitioners, the volume is filled with thought-provoking insights into the nature of current programmatic interventions for independent child migrants. It further invites critical reflection on the complex socio-economic, political, and cultural contexts in which migration decisions are taken. Contributors recognize that independent child migrants, despite vulnerabilities, are active decision-makers in determining movement, responding to violent and discriminatory situations, resisting stereotypical assumptions, and figuring out integration and life choices as these are shaped by existing structural opportunities and constraints. This is the 136th volume in this series. Its mission is to provide scientific and scholarly presentations on cutting edge issues and concepts in child and adolescent development. Each volume focuses on a specific new direction or research topic and is edited by experts on that topic.

Groundwater Remediation Groundwater Remediation

Groundwater is one of the Earth’s most precious resources. We use it for drinking, bathing, and many other purposes. Without clean water, humans would cease to exist. Unfortunately, because of ignorance or lack of caring, groundwater is often contaminated through industrialization, industry, construction or any number of other ways. It is the job of the environmental engineer to remediate the contaminated groundwater and make what has been tainted safe again.Selecting the proper remediation strategy and process is the key to moving forward, and, once this process has been selected, it must be executed properly, taking into consideration the costs, the type of contaminants that are involved, time frames, and many other factors. This volume provides a broad overview of the current and most widely applied remedial strategies. Instead of discussing these strategies in a generic way, the volume is organized by focusing on major contaminants that are of prime focus to industry and municipal water suppliers. The specific technologies that are applicable to the chemical contaminants discussed in different chapters are presented, but then cross-referenced to other chemical classes or contaminants that are also candidates for the technologies. The reader will also find extensive cost guidance in this volume to assist in developing preliminary cost estimates for capital equipment and operations & maintenance costs, which should be useful in screening strategies. The eight chapters cover all of the major various types of contaminants and their industrial applications, providing a valuable context to each scenario of contamination. This is the most thorough and up-to-date volume available on this important subject, and it is a must-have for any environmental engineer or scientist working in groundwater remediation.
