This book addresses why, whether and how the existing legal framework on water management in China could make climate change adaptation a mainstream issue. The book uses a table to illustrate the distinctions and similarities between IWRM and water-centered adaptation to analyze the possibilities of mainstreaming adaptation. The new water-planning processes and EIA are also illustrated in the form of figures showing the differences after factoring in adaptation considerations. Interviews with water managers to obtain their perception and attitudes towards climate change adaptation offer new perspectives for readers. The adaptation- mainstreaming approach, which finds a way to balance various interests and tasks, will arouse the interests of those readers who argue that climate change is only one of the issues challenging water management, and that poverty reduction, environmental protection and living standard improvement are even more important. Readers will also be interested to discover that the adaptation mainstreaming approach could be applied in water management institutions such as water planning and EIA. In addition, the book offers a clear explanation of the challenges of adaptation to the existing water-related legal framework from a theoretical perspective, and provides theoretical and practical recommendations.

The purpose of this paper is to present a methodology for estimating space-time stochastic properties of local climatic factors reflecting global climate change. Specifically, daily precipitation amount and daily mean temperature are considered and illustrated with application to the state of Nebraska, U. S. A. Furthermore, a drought index with and without global climate change is examined. The magnitude and consequences of regional response to anticipated climatic changes are uncertain (Houghton et al., 1990). Typical questions to be answered are: can time series of hydrological events or 10cal climatic variables such as daily temperature be conditioned in scenarios of future climate change and if so, how can this be utilized ? Can extreme historical drought events be reproduced by a stochastic hydroc1imatological model ? Can such a model be used with General Circu1ation Model (GCM) outputs to evaluate the regional/local effects of climate change scenarios? The approach presented in this paper is an extension of the usual analysis of regional hydrometeorological impacts of climate change: we propose to examine time series of GCM produced daily atmospheric circulation patterns (CP), thought to be relatively accurate GCM output to estimate local climatic factors. The paper is organized as follows. First, daily CPs are classified and analyzed statistically, first for historical and then for GCM produced data. Next, the height of the 500 hPa pressure field is introduced as an additional physically relevant variable influencing local climatic factors within each CP type."

Analytics can support numerous aspects of water industry planning, management, and operations. Given this wide range of touchpoints and applications, it is becoming increasingly imperative that the championship and capability of broad-based analytics needs to be developed and practically integrated to address the current and transitional challenges facing the drinking water industry. Analytics will contribute substantially to future efforts to provide innovative solutions that make the water industry more sustainable and resilient. The purpose of this book is to introduce analytics to practicing water engineers so they can deploy the covered subjects, approaches, and detailed techniques in their daily operations, management, and decision-making processes. Also, undergraduate students as well as early graduate students who are in the water concentrations will be exposed to established analytical techniques, along with many methods that are currently considered to be new or emerging/maturing. This book covers a broad spectrum of water industry analytics topics in an easy-to-follow manner. The overall background and contexts are motivated by (and directly drawn from) actual water utility projects that the authors have worked on numerous recent years. The authors strongly believe that the water industry should embrace and integrate data-driven fundamentals and methods into their daily operations and decision-making process(es) to replace established "rule-of-thumb" and weak heuristic approaches - and an analytics viewpoint, approach, and culture is key to this industry transformation.

Groundwater beneath cities is important. Water utilities and private abstractors use is it as a secure source of water-supply and municipal authorities have to cope with it when planning sanitation and using underground space for building and transportation infrastructure, but all too often neither have a comprehensive understanding. This Guidebook aims to highlight what water utilities and municipal government can do to improve groundwater assessment, management and monitoring to avoid experiencing 'nasty surprises'. Groundwater, especially from deeper aquifers, is a critical resource for enhancing urban water-supply security under climate-change stress. But to achieve its use sustainably will require adaptive promotion of resource management and protection, according to local circumstances. In recent times municipal governments are making much more use of urban subsurface space (especially down to 15-metres depth) for construction. Traditionally the drainage and stability of such structures were achieved by individual site investigation, but today a more coordinated approach is needed to managing shallow groundwater conditions. The Guidebook is divided into three complementary parts: Part A is intended for guidance of water-utility, together with water-resource agency and municipal sanitation department, staff working to improve urban water-supply resilience, with its inevitable requirement to get more involved in groundwater management. Part B is intended for guidance of municipal government authorities working to improve the design and execution of urban infrastructure to avoid potentially costly subsurface drainage issues, structural instability and groundwater flooding problems. Part C provides a series of case histories on urban groundwater management from around the world.

This book examines India's transboundary river water disputes with its South Asian riparian neighbours - Pakistan, Bangladesh, Nepal and Bhutan. It explores the history of disputes and cooperation over the transboundary river water in this region as well as discusses current disputes and future concerns. It analyses how and why existing transboundary river water sharing treaties between India and its South Asian riparian neighbours are confronted with challenges. The book indicates that India's transboundary river water disputes with its South Asian riparian neighbours are likely to escalate in coming years due to the widening of the demand-supply gap in the respective countries. It further shows the impact of bilateral relations on the resolution of transboundary river water disputes, even as cordial relationships do not always guarantee the absence of river water disputes between riparian states. The book looks at some key questions: How political are India's transboundary rivers water disputes in South Asia? Why do the roots of India's river water disputes with Bangladesh and Pakistan lie in the partition of the British India in 1947? Why are there reservations against India's hydroelectricity projects or allegations of water theft? Is it possible to resolve transboundary river water disputes among these South Asian countries? This book will greatly interest scholars and researchers working in the areas of river management, environmental politics, transnationalism, water resources, politics and international relations, security studies, peace and conflict studies, geopolitics, development studies, governance and public administration, and South Asian studies in addition to policymakers and journalists.

The book is intended as a handbook providing detailed instructions for the correct conducting of jar tests, which are needed for the optimisation of the coagulation/flocculation process. It contains the essential theoretical background of coagulation/flocculation, including a description of the influence of different parameters on the coagulation efficiency of various impurities (e.g. pH value and type/dose of coagulant), and floc properties and their separation (e.g. mixing intensity, mixing time, but also type/concentration of coagulant and impurities). The principle of jar tests is explained and parameters possible to optimize (i.e. coagulation pH, coagulant dose, flocculation aid dose, mixing intensity and mixing time) are discussed. Laboratory equipment for jar tests is proposed, including mixers and instructions for calculating a mixing intensity (necessarily expressed by the global shear rate/velocity gradient G). Mixing intensities for various purposes are recommended. Detailed practical instructions of how to perform jar tests follow, including a determination of the dose of reagents for pH adjustment and coagulant dose, dosing sequence, floc separation after jar tests by sedimentation and/or centrifugation simulating sand filtration, sampling, measuring necessary parameters (pH, coagulant residuals, alkalinity, residual impurity concentrations etc.), data recording, data processing and jar test evaluation (with specific examples). The handbook also contains a supplementary part with tables for conversion of the molar to mass concentration (and vice versa) of coagulants, and instructions for diluting coagulants and reagents for pH adjustment.

This book is the product of a worldwide collaboration among UN water resources programs, prominent national water resources operating agencies and selected academic specialists. It deals directly with some of the most difficult problems water engineers, managers and decision makers face when designing and implementing water resources infrastructure under new patterns of climate variability. Projecting the probabilities and risks associated with such events has traditionally been central to water resources planning and modeling. Such projections have been keys to social, environmental, economic, and financial investment decisions making. However, our contemporary world has called into question some of the traditional methods and approaches to formulating such projections. This collection provides practical grounding in selected advances already in place and practiced by leading institutions; advances that could be readily adapted by the water resources engineering and design professionals to better deal with risk and uncertainty in a non-stationary climate world. We believe this book opens important venues which can help to enhance the water and climate dialogues worldwide.

Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Readers will also find valuable guidelines to ensure sustainable and innovative solutions for wastewater treatment in the light of climate change, resource, demand, and funding challenges.Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

Excessive groundwater pumping, groundwater contamination, and subsurface thermal anomalies have occurred frequently in Asian coastal cities, greatly disturbing the urban aquifer and the subsurface environment. In this volume, the relationship between the stage of a city s development and subsurface environment issues have been explored. Intensive field surveys were done in Tokyo, Osaka, Seoul, Taipei, Bangkok, Jakarta, and Manila. New, advanced methods, including satellite, tracer techniques, and the social economy model, were developed to evaluate subsurface conditions. Groundwater storage and groundwater recharge rates, as well as the accumulation and transport of pollutants, have been compiled as integrated indices of natural capacities under climate and social changes, and used to evaluate the vulnerability risk for all cities. The indices have been made on a yearly basis for seven cities for a century (1900 2000). Using these indicators it is now possible to manage groundwater resources in a sustainable fashion. This volume is indispensable to researchers in hydrology, coastal oceanography, civil engineering, urban geography, social economy, climatology, geothermics, and urban management.

This book uses resource economics costing approaches incorporating externalities to estimate the returns for the country's irrigation and demonstrates how underestimating the cost of water leads farmers to overestimate profits. The importance of the subject can be judged in light of the fact that India is the largest user of groundwater both for irrigation and for drinking purposes, pumping twice as much as the United States and six times as much as Europe. Despite water's vital role in ensuring economic security for the nation and farmers alike by supporting more than 70% of food production, water resource economists are yet to impress upon farmers and policymakers the true value of water and the urgent need for its sustainable extraction, recharge and use. In an endeavor to promote more awareness, the book further delineates the roles of the demand side and supply side in the economics of irrigation, and explains how the cost of water varies with the efforts to recharge it, crop patterns, degrees of initial and premature well failure and degrees of externalities. It also discusses the importance of micro-irrigation in the economics of saving water for irrigation, estimating the marginal productivity of water and how it improves with drip irrigation, the economics of water sharing and water markets, optimal control theory in sustainable extraction of water, payment of ecosystem services for water and how India can effectively recover. In closing, the book highlights the role of socioeconomic and hydrogeological factors in the economics of irrigation, which vary considerably across hard rock areas and the resulting limitations on generalizing.

This book presents three distinct pillars for analysis, design, and planning: urban water cycle and variability as the state of water being; landscape architecture as the medium for built-by-design; and total systems as the planning approach. The increasing demand for water and urban and industrial expansions have caused myriad environmental, social, economic, and political predicaments. More frequent and severe floods and droughts have changed the resiliency and ability of water infrastructure systems to operate and provide services to the public. These concerns and issues have also changed the way we plan and manage our water resources. Focusing on urban challenges and contexts, the book provides foundational information regarding water science and engineering while also examining topics relating to urban stormwater, water supply, and wastewater infrastructures. It also addresses critical emerging issues such as simulation and economic modeling, flood resiliency, environmental visualization, satellite data applications, and digital data model (DEM) advancements. Features: Explores various theoretical, practical, and real-world applications of system analysis, design, and planning of urban water infrastructures Discusses hydrology, hydraulics, and basic laws of water flow movement through natural and constructed environments Describes a wide range of novel topics ranging from water assets, water economics, systems analysis, risk, reliability, and disaster management Examines the details of hydrologic and hydrodynamic modeling and simulation of conceptual and data-driven models Delineates flood resiliency, environmental visualization, pattern recognition, and machine learning attributes Explores a compilation of tools and emerging techniques that elevate the reader to a higher plateau in water and environmental systems management Water Systems Analysis, Design, and Planning: Urban Infrastructure serves as a useful resource for advanced undergraduate and graduate students taking courses in the areas of water resources and systems analysis, as well as practicing engineers and landscape professionals.
