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...

The purpose of this book is to bridge the gap between the fundamentals of GIS and applications of this technology to the practice of environmental engineering and science. Students are provided a complete picture of GIS including data availability and fundamental spatial analysis techniques using hands-on environmental applications. A series of case-studies are used to demonstrate how GIS can enhance environmental science and engineering design and analysis. This combination of active GIS learning supplemented with case-study based reinforcement helps the student (and the practitioner) not...

GIS and Geocomputation for Water Resource Science and Engineering not only provides a comprehensive introduction to the fundamentals of geographic information systems but also demonstrates how GIS and mathematical models can be integrated to develop spatial decision support systems to support water resources planning, management and engineering. The book uses a hands-on active learning approach to introduce fundamental concepts and numerous case-studies are provided to reinforce learning and demonstrate practical aspects. The benefits and challenges of using GIS in...
