Groundwater Resources Modeling: A Case Study from the U.K.

As populations grow, climates change, and water resources (and budgets) dwindle, well-documented, wellcoordinated, and well-maintained groundwater management tools are needed more than ever. This book (Shepley et al. 2012), a collection of papers written specifically for this volume, provides not only case studies of individual groundwater modeling efforts, but also an important case study of an overall effort to model a nation’s aquifers. I read this book with great personal interest because I have been involved with a similar modeling program in Texas. (Texas is not a nation, but it used to be!) This collection of papers documents a national program administered by the United Kingdom’s Environment Agency between 1998 and 2009 to develop groundwater flow models of England’s and Wales’ primary bedrock aquifers. While most nonnatives will be aware of the internationally famous Chalk Aquifer, the book also discusses the Permo-Triassic Sandstone Aquifer, the Carboniferous Limestone Aquifer, and the Scottish alluvial aquifers, among others. The editors were closely involved in the national effort; therefore, they were well-positioned to coordinate and deliver a thorough and well-documented product. Broadly, the papers in the book fall into one of three categories: (1) organization and execution of the national modeling effort; (2) descriptions of the modeling efforts; and (3) discussions of conceptual model issues, methodologies, and use of the models. After a foreword by Mary P. Anderson (who also served as a reviewer of the volume), the first five papers focus on the organization and execution of the modeling program, including the history of modeling in the United Kingdom, the background of the national modeling program, the management of the program and its standards, how stakeholders were included in the process, and how final models have been served to stakeholders and others. Eight of the remaining 17 papers are primarily focused on descriptions of specific regional modeling efforts, with the other nine papers focused on conceptual model issues, methodologies, and use of the models. Topics include estimating recharge, using modeling to better understand groundwater flow, and developing and
