Developing an Appropriate Contaminated Land Regime in China: Lessons Learned from the US and UK

by Xiaobo Zhao

This book explores the complex package of mechanisms used to identify, record, manage and remediate contaminated land, including the system for allocating liabilities that has been set up by China’s contaminated land law and accompanying administrative decrees and environmental standards. Statutory control of soil or land contamination is a comparatively new phenomenon for Chinese lawmakers and researchers. After more than ten years of preparation, China recently adopted its first nationwide contaminated land law—the Law of the People’s Republic of China on the Prevention and Control of Soil Contamination, which entered into effect in the beginning of 2019. The law deals exclusively with risk management in connection with soil contamination, and the remediation of contaminated land. This book analyzes various facets of how China is managing the risks associated with soil contamination and remediating contaminated sites by means of legislation. Chapters 1 and 2 reveal the current extent of the soil contamination problem in China and the initial policy responses of the country’s central government. In turn, Chapters 3 and 4 address the regulatory frameworks and the latest contaminated land legislation at both the local and national level. Lastly, Chapters 5 through 9 offer concrete recommendations, based on lessons learned in the US and UK, for reforming contaminated land management in China. Overall, the book covers the past, present and future of contaminated land management in China, making it of interest to environmental policymakers, administrators, academics, lawyers and engineers engaged in soil or environmental protection. Further, it offers a source of reliable information for those who want to learn more about China’s environmental legislation and contaminated land management policy.

Developing an Appropriate Contaminated Land Regime in China: Lessons Learned from the US and UK

by Xiaobo Zhao

Like all industrialized countries, China has encountered increasing problems with land contamination in recent years. Abandoned mining and manufacturing sites and obsolete industrial complexes, while also creating new polluting industrial enterprises, represent impending environmental threats. More importantly, a number of social and economic problems have developed and must be dealt with, in some cases urgently. Contaminated land laws and regulations have been established and have evolved in the US and UK and many other jurisdictions over the past few decades. These regimes have substantially influenced the relevant legislation in the context of numerous Asian and European countries and will inevitably benefit similar legislative efforts in China. This book is the first monograph that focuses on how China can learn from the US and UK with respect to contaminated land legislation and comprehensively illustrates how contaminated land law could be created in China. It will be of interest to academics and practitioners in environmental law in China, as well as the US and UK.

Coupled DEM-CFD Analyses of Landslide-Induced Debris Flows (Springer Tracts in Civil Engineering)

by Tao Zhao

This book reflects the latest research results in computer modelling of landslide-induced debris flows. The book establishes an understanding of the initiation and propagation mechanisms of landslides by means of numerical simulations, so that mitigation strategies to reduce the long-term losses from landslide hazards can be devised. In this context, the book employs the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) to investigate the mechanical and hydraulic behaviour of granular materials involved in landslides – an approach that yields meaningful insights into the flow mechanisms, concerning e.g. the mobilization of sediments, the generation and dissipation of excess pore water pressures, and the evolution of effective stresses. As such, the book provides valuable information, useful methods and robust numerical tools that can be successfully applied in the field of debris flow research.

A Brief Overview of China’s ETS Pilots: Deconstruction and Assessment of Guangdong’s Greenhouse Gas Emission Trading Mechanism

by Daiqing Zhao Wenjun Wang Zhigang Luo

This book systematically introduces readers to the framework of China’s ETS pilots, exploring their design and operating process, the current state of the carbon market, and various barriers encountered. To do so, it deconstructs the Guangdong ETS, which is the largest and most representative of China’s seven ETS pilots. The book subsequently describes and evaluates all seven pilots in terms of their efficiency, macro and micro effects, the method involved in the DEA model, the CGE model, and cost-benefit analysis. In turn, in the assessment section it demonstrates how some ETS pilots have failed to control carbon emissions due to inordinately high emissions quotas issued by the local government etc. Further, it argues that ETS should focus on those industries with large emissions and high mitigating potential for the time being, and then gradually expand the scale of its coverage.As China’s national ETS is slated for launch on the basis of the lessons learned from the ETS pilots, the book offers a timely and valuable resource for all those who want to understand and forecast the development of China’s ETS. It includes a wealth of descriptions and explanations of Chinese government policies involving carbon emissions control, making it a unique resource.

Fundamentals of Computational Geoscience: Numerical Methods and Algorithms (Lecture Notes in Earth Sciences #122)

by Chongbin Zhao Bruce E. Hobbs Alison Ord

Geoscience is a fundamental natural science discipline dealing with the origin, evolutionary history and behaviour of the planet Earth. As a result of its complicated and complex nature, the Earth system not only provides the necessary materials and environment for mankind to live, but also brings many types of natural disasters, such as earthquakes, volcanic eruptions, tsunamis, ?oods and tornadoes, to mention just a few. With the ever-increasing demand for improving our living standards, it has been recognized that the existing natural resources will be exhausted in the near future and that our living environments are, in fact, deteriorating. To maintain the sustainable development of our living standards and the further improvement of our living environments, an inevitable and challenging task that geoscientists are now confronting is how accurately to predict not only the occurrences of these natural disasters, but also the locations of large concealed natural resources in the deep Earth. For this reason, geoscientists must study the processes, rules and laws, by which the Earth system operates, instead of simply describing and observing g- science phenomena.

3D Dynamic Scene Analysis: A Stereo Based Approach (Springer Series in Information Sciences #27)

by Zhengyou Zhang Olivier Faugeras

he problem of analyzing sequences of images to extract three-dimensional T motion and structure has been at the heart of the research in computer vi­ sion for many years. It is very important since its success or failure will determine whether or not vision can be used as a sensory process in reactive systems. The considerable research interest in this field has been motivated at least by the following two points: 1. The redundancy of information contained in time-varying images can over­ come several difficulties encountered in interpreting a single image. 2. There are a lot of important applications including automatic vehicle driv­ ing, traffic control, aerial surveillance, medical inspection and global model construction. However, there are many new problems which should be solved: how to effi­ ciently process the abundant information contained in time-varying images, how to model the change between images, how to model the uncertainty inherently associated with the imaging system and how to solve inverse problems which are generally ill-posed. There are of course many possibilities for attacking these problems and many more remain to be explored. We discuss a few of them in this book based on work carried out during the last five years in the Computer Vision and Robotics Group at INRIA (Institut National de Recherche en Informatique et en Automatique).

Pelton Turbines

by Zhengji Zhang

This book concerns the theoretical foundations of hydro mechanics of Pelton turbines from a viewpoint of engineering. For reference purposes all relevant flow processes and hydraulic aspects in a Pelton turbine have been analyzed completely and systematically. The analyses especially include the quantification of all possible losses existing in the Pelton turbine and the indication of most available potential for further enhancing the system efficiency. As a guideline the book therefore supports further developments of Pelton turbines with regard to their hydraulic designs and optimizations. It is thus suitable for the development and design engineers as well as those working in the field of turbo machinery. Many laws described in the book can also be directly used to simplify aspects of computational fluid dynamics (CFD) or to develop new computational methods. The well-executed examples help better understanding the related flow mechanics.

Hydraulic Transients and Computations

by Zh. Zhang

This book describes the fundamental phenomena of, and computational methods for, hydraulic transients, such as the self-stabilization effect, restriction of the Joukowsky equation, real relations between the rigid and elastic water column theories, the role of wave propagation speed, mechanism of the attenuation of pressure fluctuations, etc. A new wave tracking method is described in great detail and, supported by the established conservation and traveling laws of shockwaves, offers a number of advantages. The book puts forward a novel method that allows transient flows to be directly computed at each time node during a transient process, and explains the differences and relations between the rigid and elastic water column theories. To facilitate their use in hydropower applications, the characteristics of pumps and turbines are provided in suitable forms and examples. The book offers a valuable reference guide for engineers and scientists, helping them make transient computations for their own programming, while also contributing to the final standardization of methods for transient computations.
