Groundwater Lowering in Construction

The late Pat Cashman was the leading British exponent of groundwater control for his generation, championing a practical and straightforward approach for more than forty years.Dr. Martin Preene draws on thirty years’ experience of groundwater control and groundwater management gained with contractors and consultants in more than forty countries worldwide. He currently operates as an independent groundwater specialist via Preene Groundwater Consulting.

"Totally comprehensive in scope and coverage, the book will likely become - if not already - the standard work on subsurface dewatering on small- to medium-sized projects. Although practical, the book is not short on theory or analysis."— Tunnels and Tunnelling International Praise for the Second Edition"This is the book that the dewatering sector really needs—it is reliably based on sound theory and profound understanding of the physical processes, yet is presented in a very accessible and user-friendly manner. It draws on many, many decades of experience, and yet is utterly up to date, even including an intriguing glimpse into the future at the end of the book…It is a one-stop shop for the dewatering practitioner—who can nonetheless rest assured that the theoretical basis of the methods presented is flawless."— Professor Paul L. Younger, FGS, FICE, C.Geol., C.Eng., FREng, University of Glasgow, Scotland, UK"An essential and highly practical tool for all hydrogeologists and geotechnical and civil engineers involved in the quantified design and planning, construction, monitoring, operation, decommissioning, regulation and assessment of environmental impacts of groundwater lowering and dewatering systems."–– Trevor Muten in Quarterly Journal of Engineering Geology and Hydrogeology"The main difference from the previous edition is the introduction of a chapter on the environmental effects of dewatering, reflecting increased societal and regulatory focus on these aspects. However, new sections on cutoff methods, long-term systems and contaminated land all reflect developments in the industry over this period."–– Mike Streetly in Quarterly Journal of Engineering Geology and Hydrogeolog"The best reference on this topic available...and will prove useful to a wide variety of readers ranging from junior construction engineers or dewatering contractors to theoretical hydrogeologists and environmental managers. It is rare that a book is able to bridge the gap between theoretical design guidance and practical application."— S.N. Sterling, University of Waterloo, Canada"The book provides an excellent and practical account of many aspects of dewatering in construction, usefully including a detailed discussion of permanent groundwater control systems. It provides a good account of basic hydrogeology and the history of the development of the science, and includes a thorough chapter on site investigations for dewatering design. Dewatering design and the installation and operation of various types of dewatering system are described in detail, making the book an excellent resource, both for practical purposes and for training. Each chapter has a good reference list for further, more detailed reading. I certainly recommend the book for both practitioners and teaching institutions."— John Waterhouse, Golder Associates Pty Ltd, West Perth, Australia"[This second edition] takes a well received and respected book on this niche subject and brings it fully up to date."— David Richards, University of Southampton, UK
