Sponsored by the Urbanization Effects on Groundwater Task Committee of the Groundwater Hydrology Committee of the Groundwater Council of the Environmental and Water Resources Institute of ASCE. What are the regional differences in stormwater and wastewater management technology approachesØto urbanization? How can wetland extent and function be incorporated as an integral part of urban infrastructure systems, including effects on groundwater level? Addressing questions such as these, this book presents sustainable systems engineering technologies and applies them to the management of water in urban areas. To promote sustainable management of water, chapters examine the interactions among energy, environment, ecology, and socioeconomic paradigms and describe the challenges and opportunities facing engineers, scientists, and policymakers. Topics fall into four broad categories: water supply and pollution prevention; stormwater management with regional infiltration technologies; Ø wastewater treatment and disposal with nutrient removal; and Ø low impact development with landscape architecture technologies. Ø Within these categories, chapters range from the fundamental theory to physical, chemical, and biological processes, to the coupled human and natural environment, to the representation of simulated evolutionary pathways. This volume makes a strong case for sustainable development and management and helps to expose how sensitive key water quantity and quality management targets are to urban development.

This manual comprises a holistic view of urban runoff quality management. For the beginner, who has little previous exposure to urban runoff quality management, the manual covers the entire subject area from sources and effects of pollutants in urban runoff through the development of management plans and the design of controls. For the municipal stormwater management agency, guidance is given for developing a water quality management plan that takes into account receiving water use objectives, local climatology, regulation, financing and cost, and procedures for comparing various types of controls for suitability and cost effectiveness in a particular area. This guidance will also assist owners of large-scale urban development projects in cost-effectively and aesthetically integrating water quality control to the drainage plan. The manual is also directed to designers who desire a self-contained unit that discusses the design of specific quality controls for urban runoff.

More than 50% of the world's population already live in cities, and the proportion is rising extremely rapidly towards developed country levels of more than 90%. Groundwater from wells is the major source of water supply for many of these cities, however, groundwater is polluted by the cities that overlie it and sewerage systems are often absent, or leak. Industrial landuse implies the use of large quantities of chemicals, and it is the poor disposal and accidental spillage of these chemicals which results in the contamination of virtually every industrial site in the world. Much of this pollution migrates deeper to damage groundwater. Groundwater has slow turnover time, often measured in decades and centuries, reducing the self-cleansing capacity. Urban aquifers are therefore vitally important but very fragile, easily damaged and slow to repair. Urban groundwater problems and solutions vary greatly around the world. Mature cities often have remote and clean water supplies, good sewerage systems, strict controls on groundwater and land use, and declining industries. However, they have a legacy of more than one hundred years of waste disposal and industrially-contaminated land which continues to cause problems. Rapidly urbanising cities are frequently dependent on local groundwater and have poor sanitation and uncontrolled industry. These factors present many immediate risks to human health. This book explains the nature and value of urban groundwater, discussing the types of pollutants that are found, and their sources. The unique aspect of this book is the in-depth discussion of six different urban environments, complete with case studies. These environments are: Mature industrial cities; Arid-zone cities; Weathered crystalline aquifers in sub-Saharan Africa; Cities overlying karst aquifers; Alluvial aquifer systems; Shallow aquifers in Mediterranean climates.

The uncontrolled utilization of natural resources to supply to the water demands of the ever-growing population has brought about worldwide scarcity. The supply shortage has resulted in conflicts between countries, created prolonged drought, closing of industrial units, shifting of local inhabitants etc. The abnormality in climatic patterns due to global warming has only enhanced the uncertainties. Unregulated discharge of waste water into fresh water resources is also polluting the available water resources and making them non-utilizable. That is why the discrepancy between water supply and demand is slowly but steadily becoming a problem, which may lead to conflict and inequality all over the world. The present investigation is an attempt to find the impact of urbanization in the face of climatic uncertainties on water shortage or scarcity. How is climate responsible? What urbanization factors have an influence on the extent of shortages? What is the role of the socio-economic status of the inhabitants? Industrialization? Consumption pattern? Each of the causes and effects were analyzed with the help of data from a climate model, which was then fed into a hydrologic model. The hydrologic output data was then put into various other novel simulation platforms to predict the uncertainties that can be caused by urbanization in various sectors of the regions of interest. The impact was calculated based on IPCC recommended climatic and five distinct urbanization scenarios. The study results will help to predict what is in store of those living in the developing countries. Possible mitigation measures are also discussed.

In past decades, urban water management practices focused on optimizing the design and operation of water distribution networks, wastewater collection systems, and water and wastewater treatment plants. However, municipalities are now faced with aging urban water infrastructures whose operation must be improved and expanded to maintain current high standards of living as well as new challenges such as climate change, systems sustainability and water quality issues. Integrating the latest developments in urban water hydrology and management, Urban Water Engineering and Management takes a system approach to urban water hydrology, engineering, planning and management, supplying examples and case studies and highlighting pressing issues such as urban water governance, disaster management, and climate change impacts on urban areas. The book draws attention to climate change as a main concern of this century by focusing on its impact the components of water cycle. The book covers modeling of urban water cycle components, urban water supply, and distribution systems demand forecasting. It also presents classical issues, such as design of water distribution networks and wastewater and storm collection in urban settings, from a system's perspective. The text also includes a discussion of water governance and disaster management in urban areas and the urbanization effects on the environment and the needed water infrastructure development in urban areas. Against this background, the authors discuss the importance of understanding the principles of simulation, optimization, multiple-criterion decision making, and conflict resolution for successful, integrated urban water management. They explore integrated water management and planning solutions for incorporating structural and nonstructural means to achieve the best operational schemes at affordable costs, going beyond using the existing structures and physical limitations on water availability to include technical, social, political, and economic aspects of better water and wastewater management in urban areas. Written and designed especially for intermediate and advanced courses/modules in water resources in civil and environmental engineering, and in urban planning, the book can be used as a textbook for civil engineering, urban and regional planning, geography, environmental science, and in courses dealing with urban water cycle. It also introduces new horizons for engineers as well as policy and decision makers who plan for future urban water and regional sustainability. Engineers and planners, especially those who work on design, planning, and management of urban systems and/or community development, can use this book in practice because it deals with a broad range of real world urban water problems.

Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and managing the impacts of urban stormwater on wetlands. The book documents the background, methods, and results of the research and uses the information to draw conclusions about managing wetland ecosystems in urban areas. The project culminates in a set of comprehensive guidelines for the management of wetland hydrology. While the focus of this research is regional in nature, its applications are broad. First, the research shows how to measure and assess the impact of urbanization on wetlands. Secondly, it presents scientific approaches available for use in an integrated assessment of wetland condition. And thirdly, it provides guidelines for biomonitoring wetlands using multiple indicators. Wetlands and Urbanization presents an integrated watershed approach to the scientific evaluation of the impact of landscape urbanization on wetland functions. It associates the source of impact (the landscape) with the sink (the wetland), relates findings to implications for future planning and management of watersheds and provides a model for future comprehensive investigations of wetland impacts from urbanization.

Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.

Groundwater systems are vital to both society and the environment, supporting food production and many other ecosystem services. Sustainable management of this vital resource for future generations requires a sound understanding of how groundwater might respond to the inevitable changes in future climate. In this volume, recent developments within the interlinked areas of the response of groundwater systems to climate variability and climate change are highlighted, using contemporary field investigations and monitoring of aquifers, numerical simulations of aquifer response to climate change predictions and paleohydrogeological studies of ancient groundwater systems. The book provides an up-to-date description of the relationship between groundwater behaviour and ancient, historical, current and future climates for a range of diverse aquifer systems around the world.
