UGROW (Urban GROundWater) represents one of the most advanced urban water management tools produced to date and fully integrates all urban water system components including groundwater. It will raise the awareness of the interaction between urban water system components, support management decision-making, and solve a wide range of urban water problems. The model has a sound scientific basis, is computationally efficient, and is supported by outstanding graphics. Developed as part of the sixth Phase of UNESCO’s International Hydrological Programme (IHP-IV), UGROW was tested and refined under a range of demanding urban conditions. Book includes UGROW software CD-ROM and instruction manual.

During the past three decades, urban groundwater has emerged as one of the world’s most pressing issues. Explosive population growth, most prevalent in cities, has placed an inordinate demand on groundwater supply, prompting concerns for its long-term sustainability at a time when the quality of available groundwater resources is being increasingly degraded by anthropogenic activity. Cities less reliant on groundwater for potable supply are equally obliged to manage subsurface water with cautious respect since rising groundwater levels can generate a myriad of problems such as unstable land slopes, flooded basements, tunnels and electrical utilities, and the release of polluted water to urban wetlands, springs and streams.Challenges in Urban Groundwater is premised on a growing recognition that most urban groundwater problems are not uniquely associated with any particular region or hydrogeological environment, and much can be learned by understanding the successes and failures of others. It showcases the best urban groundwater papers presented at the International Geological Congress held in Florence, Italy in 2004, and is supplemented by contributions solicited from other world experts active in urban groundwater research. Topics covered range from the urban water balance and rising groundwater levels to groundwater contamination and the role of aquifer modelling.

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.

Groundwater Dependent Ecosystems (GDEs) frequently exhibit rich biological diversity and can provide enormous economic wealth. In recent years, GDEs in many industrialized countries have shown signs of serious degradation, primarily the result of groundwater abstraction and pollution. Many such systems, including a number of well documented cases in Eastern Europe, are no longer sustainable. As a consequence, the conservation and sustainable management of GDEs has emerged as one of the most urgent environmental research priorities of our time. A large percentage of the world’s population lives in cities and either depends on, or is affected in some way, by groundwater. Moreover, groundwater has become a very important and complex issue that attracts the interest of many diverse stakeholders. Many problems related to groundwater and ecosystems are shared by countries throughout the world and there is growing recognition that much can be gained by co-operation on an international scale. This is no time to be complacent and it is critical that key problems be identified, that the potential consequences of these problems be understood, and that the development of solutions begins urgently. Important data gaps must be recognized and filled without delay

National and global security can be assessed in many ways but one underlying factor for all humanity is access to reliable sources of water for drinking, sanitation, food production and manufacturing industry. In many parts of the world, population growth and an escalating demand for water already threaten the sustainable management of available water supplies. Global warming, climate change and rising sea level are expected to intensify the resource sustainability issue in many water-stressed regions of the world by reducing the annual supply of renewable fresh water and promoting the intrusion of saline water into aquifers along sea coasts, where 50% of the global population reside. Pro-active resource management decisions are required, but such efforts would be futile unless reliable predictions can be made about the impact of the changing global conditions on the water cycle and the quality and availability of critical water reserves. Addressing this wide spectrum of issues, a team of expert authors discusses here the impacts of climate change on the global water resources, the long-term resource management goals at global and local scales, the data requirements and the scientific and technical advances necessary to mitigate the associated impacts.
