This paper highlights key urban groundwater issues and management needs. It also raises awareness and understanding of hydrogeological processes in urban areas and provides a framework for the proper and systematic consideration of groundwater dimensions in urban management. This paper suggests options for greater sustainable development and management of groundwater in urban areas.
What are the regional differences in stormwater and wastewater management technology approaches to urbanization? How can wetland'extent and function be incorporated as an integral part of urban infrastructure systems, including effects on groundwater level? The Effects of Urbanization on Groundwater: An Engineering Case-Based Approach to Sustainable Development addresses these and a number of other key questions involving all phases of impact from the interactions among energy, environment, ecology, and socioeconomic paradigms in human society. To promote the concept of sustainable management, this unique book presents and applies sustainable systems engineering technologies and states the challenges of and opportunities for science, technology, and policy related to sustainable management of water. This book is organized into four parts: water supply and pollution prevention; storm water management with regional infiltration technologies; wastewater treatment and disposal with nutrient removal; and low impact development with landscape architecture technologies. These thematic areas cover the aspects from the fundamental theory to physical, chemical, and biological processes to the coupled human and natural environment, and to the representation of simulated evolutionary pathways. The Effects of Urbanization on Groundwater: An Engineering Case-Based Approach to Sustainable Development is timely and makes a strong case for sustainable development and management. It will help expose just how sensitive key water quantity and quality management targets are to urban development.
In 2007, the world's urban population surpassed the number of people living in rural areas and is still growing. The number of city dwellers who do not have access to piped water and rely on groundwater is also increasing. In many Asian cities, groundwater is not only the source of domestic water but also an important resource for industrial development, making better management of groundwater resources essential for sustainable development. Because groundwater is easier to access and costs less than water from piped systems, groundwater abstraction cannot be easily regulated. Policies for groundwater management adopted in Japan and other Asian countries are compared, and technologies for efficient use of groundwater are elucidated. Groundwater contamination is also a serious problem that exacerbates water scarcity in Asian cities. Case studies illustrate the cause and consequences of naturally occurring contaminants such as arsenic and fluoride, and groundwater contamination due to anthropogenic contaminants is described. Also discussed are technologies for treating contaminated groundwater to reduce the health risks of drinking contaminated groundwater.
The perceptibly changing climate has resulted in more precipitation in a small number of short periods. As most urban water management systems were developed at a time when precipitation was distributed more evenly throughout the year, they cannot deal properly with the new circumstances, and high groundwater levels and excess water are the result. In practice, many urban dwellers are consequently confronted with flooded cellars and inaccessible urban infrastructure. To solve these phenomena in the future, a major part of the urban water programmes for the next few decades consists of restructuring and transformation of the existing urban areas, in which water management is considered as an integral part of urban renewal activities and in which its capacity is compliant with the urban area scale. With an integral approach, this book treats the relation of urbanism and water management in Dutch water cities. It also treats the financial aspects of the adjustment of existing water systems to meet the changes in the urban hydrological cycle. It presents the typology of typical current and future Dutch water cities, their urban function and the ecological and technical aspects. Separate chapters deal with the transformation of the historical city, the consolidation of the inter-war city and the restructuring of the post-war city to meet future conditions. The final chapter presents a comparison of the Dutch situation with South Korean (Seoul), Japanese (Tokyo) and German (Ruhr area) urban areas.
Urban Climates is the first full synthesis of modern scientific and applied research on urban climates. The book begins with an outline of what constitutes an urban ecosystem. It develops a comprehensive terminology for the subject using scale and surface classification as key constructs. It explains the physical principles governing the creation of distinct urban climates, such as airflow around buildings, the heat island, precipitation modification and air pollution, and it then illustrates how this knowledge can be applied to moderate the undesirable consequences of urban development and help create more sustainable and resilient cities. With urban climate science now a fully-fledged field, this timely book fulfills the need to bring together the disparate parts of climate research on cities into a coherent framework. It is an ideal resource for students and researchers in fields such as climatology, urban hydrology, air quality, environmental engineering and urban design.
Effective management of urban water should be based on a scientific understanding of the impact of human activity on both the urban hydrological cycle - including its processes and interactions - and the environment itself. Such anthropogenic impacts, which vary broadly in time and space, need to be quantified with respect to local climate, urban d
Approaches to Water Sensitive Urban Design: Potential, Design, Ecological Health, Economics, Policies and Community Perceptions covers all aspects on the implementation of sustainable storm water systems for urban and suburban areas whether they are labeled as WSUD, Low Impact Development (LID), Green Infrastructure (GI), Sustainable Urban Drainage Systems (SUDS) or the Sponge City Concept. These systems and approaches are becoming an integral part of developing water sensitive cities as they are considered very capable solutions in addressing issues relating to urbanization, climate change and heat island impacts in dealing with storm water issues. The book is based on research conducted in Australia and around the world, bringing in perspectives in an ecosystems approach, a water quality approach, and a sewer based approach to stormwater, all of which are uniquely covered in this single resource.
Groundwater issues have generated worldwide concern in recent decades. The problems are numerous: too little groundwater, too much groundwater, groundwater contaminated by either saline water or a broad spectrum of industrial and domestic pollutants. Many urban groundwater problems are not unique to any one region, which is the thinking behind this book. Many of the case studies presented here have never before been described in English. Overall, the papers represent the work and experience of researchers and groundwater professionals who have worked on urban groundwater issues in developed and less-developed nations around the world. They reveal the magnitude and scope of the problem as well as identify future challenges, potential courses of action, and emerging technologies that offer hope for the future.
Many cities in Latin America and the Caribbean are experiencing a water crisis as sources become exhausted or degraded. Urbanization, deteriorating infrastructures with a lack of funds for repairs, and inadequate polices are conspiring to cause water shortages. People are becoming concentrated in megacities, such as Mexico City with a population of almost 23 million, that have outgrown their water-supply systems. Urban areas are increasingly incapable of supplying water and sewer systems for their populations. By the year 2020, more than 500 million inhabitants of Latin America (two-thirds of.
