He has over forty-two years of professional experience in water resources engineering, hydrology, hydraulics, natural resource planning, and environmental engineering, including over thirty years in private practice. Mr. Cahill is the author of over 100 technical papers and publications on land use, stormwater management, and water quality, and is a frequent lecturer at environmental and engineering conferences. Klappentext The comprehensive guide to understanding and implementing sustainable stormwater solutions A practical introductory look at the methods and materials used in twenty-first century site design, Low Impact Development and Sustainable Stormwater Management familiarizes readers with new and emerging ideas and techniques for using rainfall runoff in a more ecologically friendly fashion. Since rainfall is the ultimate source of our water supply, treating it as a finite resource is critical if we are to meet current and future human water needs, and this reference volume explains how. Providing detailed coverage of the design process and construction concerns related to sustainable stormwater management, the book illustrates concepts through the extensive use of photographs, real-world examples of built projects, and engineering details and calculations, including worksheets and specifications. Proposing and presenting innovative engineering design ideas that differ from traditional approaches to stormwater management techniques, including maximizing vegetative cover and the use of infiltration systems, the book is a comprehensive reference on ecologically sustainable approaches to making the most of rainfall. Multidisciplinary in its approach, Low Impact Development and Sustainable Stormwater Management presents insights from landscape architects, planners, and scientists, making it an indispensible resource for anyone interested in managing rainfall runoff, from engineers and designers to developers, regulators, and students.
