Water Environment Modeling covers the formulations and applications of mathematical models that simulate water flow and chemical transport in rivers, lakes, groundwater, estuaries, coastal, and ocean waters. These models are used to evaluate the response of water environment to human interventions and serve as useful analytical tools for water pollution control and resource management. Simple and comprehensive modeling techniques and their practical applications are presented with examples and exercises, most of which are derived from actual case studies. In general, simple models can be solved analytically and comprehensive models require numerical solutions. While simple models are usually adopted for preliminary assessment of a particular water environment, comprehensive models are used to provide detailed spatial and temporal variations of pollutants in complex environments. The system-based models in the forms of integral equations are introduced as an alternative modeling approach. This textbook is ideal for advanced undergraduate students and graduate students in civil and environmental engineering and related academic fields. It is also suitable as a reference book for practicing engineers and scientists. Authors: Clark C.K. Liu is Emeritus Professor of the Department of Civil and Environmental Engineering at University of Hawaii and former Environmental Engineering Director of US National Science Foundation.

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.

This book highlights one of the most important water pollutants known as Microplastics. It has been reported that humans and the environment are dealing with microplastics particles in water and aquatic media. Despite the fact that such pollution might have mainly started out from the sea, it is now in lakes, rivers, ponds and even drinking water. This book presents as overview of microplastics in freshwater environments in different regions around the world. It discusses the ecotoxicological effects of microplastics, the removal/remediation techniques of microplastics and the role of water/wastewater treatment plants in spreading microplastics. This book is a valuable resource, covering wide aspects of microplastics from sources, detection and characterization to removal and their fate in treatment plants.

This volume certainly is a Conference Proceedings, the Proceedings of the NATO Advanced Research Workshop (ARW) on "Unsaturated Flow in Hydrologic Modeling" held at "Les Villages du Soleil" near ArIes, France from June 13 to 17, 1988. Let me therefore acknowledge properly, at the very beginning, the gratitude of all the participants to the NATO Science Committee for its generous support and worthwhile goal of bringing together scientists of many countries to communicate and share their experiences. Particular thanks are extended to the director of the program, Dr. Luis Vega da Cunha for his interest and understanding. On the other hand this volume is also, and probably more so, a Textbook that fills a gap in the field of unsaturated flow. Many treatises on the subject present the theory in its different aspects. Hardly any explain in details how the different pieces can be put together to address realistic problems at the basin scale. The various invited contributions to the ARW were structured in a subject progression much as chapters are organized in a book. The intent of the ARW was to assess the current state of knowledge in "Unsaturated Flow" and its use in "Hydrologic Modeling Practice". In a sense the interest in fundamentals of unsaturated flow in this ARW was not just for the sake of knowledge but also and primarily for the sake of action. Can such fundamental knowledge be utilized for better management of the water resource? was the basic question.

Both authors are ideally suited to prepare this book, offering a nice mix of biological and geological expertise on coral reef systems. There is a glaring gap in the market for this book - there is no literature or database that comprehensively summarises the latest remote sensing imagery for global atolls. There is no comparable book. The treatment employs state-of-the-art satellite imagery and updates the existing Atlas of Coral Reefs by Spalding et al which came out more than 20 years ago. Atolls are a favorite topic of research in the biological/ecological and geological sciences due to their unusual ring-like reef form and their laboratory-like, isolated settings. The great strength and contribution of this book is the comprehensive analysis and summary of all these different atolls and their main characteristics in one place. The writing is excellent, striking a nice balance between providing enough detail while also being accessible to a general reader. A useful resource for a range of higher education courses, undergraduate and masters level courses i.e., coastal processes and environments, coral reefs and climate change, oceans coasts and climate. One reviewer says: "This is a superb volume, which I suspect will be much referred to. The authors a pre-eminent in this, and it will be authoritative as well as useful to a wide range of people."

Methods of minimizing logging damage to soils and streams are discussed and the effects on flora and fauns are considered.

This volume aims to develop a framework for disaster and climate risk resilient livelihood system in Bangladesh using a policy oriented approach. It highlights the possible impacts of climate change on groundwater based irrigation in the country. Climate change is one of biggest challenges to society. It can lead to serious impacts on production, life and environment on a global scale. Higher temperatures and sea level rise will cause flooding and water salinity problems which will bring about negative effects on agriculture and high risks to industry and socio-economic systems in the future. Climate change will lead to many changes in global development and security especially energy, water, food, society, job, diplomacy, culture, economy and trade. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as: "Any change in climate over time, whether due to natural variability or as a result of human activity." Global climate change has emerged as a key issue in both political and economic arenas. It is an increasingly questioned phenomenon, and progressive national governments around the world have started taking action to respond to these environmental concerns.

This edited volume provides a critical discussion of particular trends that are widely recognised to influence water management by comparing them with what is actually happening in the field. Among others, these trends include water security, adaptive or integrative management, and the water-energy-food nexus, which are often presented as essential means to reaching more sustainable and resilient water use. However, the extent to which these trends have managed to structure concrete practices in water management remains uncertain. Informed by empirically grounded research, each chapter of this work engages with a particular approach, concept or theory. Together, they provide a nuanced picture of trends in water management that require universal remedies and global norms.

Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief. Stopping or reversing the trend requires management interventions. The North China Plain serves as an example. A management system is set up for a typical county. It contains three components: monitoring, decision support based on modelling, and implementation in the field. Besides all monitoring data, the decision support module contains an irrigation calculator, a box model, and a distributed groundwater model to project the outcomes of different water allocation scenarios. In view of grain security, a solution combines an adaptation of the cropping system with imports of surface water from the South. The Open Access book does not only describe the problem and the path to its solution. It also gives access to nine manuals concerning methods used. They include computer programs and the game Save the Water. The Chinese experience should be of considerable interest to other regions in the world which suffer from over-pumping of aquifers.

The book is about the discovery of a Standard Specific Baseline Mass Transfer Coefficient (KLa0)20 that represents a revolutionary change in the understanding, designing, and operation of aeration equipment, as well as providing a baseline for future research and development for water and wastewater treatment systems. It discusses the use of the Standard Model for oxygen transfer to determine the baseline, and its major finding is to show that the gas transfer model is a consistent relativistic theory of molecular interactions. Previously, the challenge was the appearance of divergences in the mass transfer coefficient estimations that defies aeration design. This normalization to a baseline is a great achievement in physics and engineering.
