Описание: Illuminating opportunities to develop a more integrated approach to municipal water system design, Natural and Engineered Solutions for Drinking Water Supplies: Lessons from the Northeastern United States and Directions for Global Watershed Management explores critical factors in the decision-making processes for municipal water system delivery. The book offers vital insights to help inform management decisions on drinking water supply issues in other global regions in our increasingly energy- and carbon-constrained world. The study evaluates how six cities in the northeastern United States have made environmental, economic, and social decisions and adopted programs to protect and manage upland forests to produce clean drinking water throughout their long histories. New York, New York; Boston and Worcester, Massachusetts; New Haven and Bridgeport, Connecticut; and Portland, Maine have each managed city watersheds under different state regulations, planning and development incentives, biophysical constraints, social histories, and ownerships. Some of the overarching questions the book addresses relate to how managers should optimize the investments in their drinking water systems. What is the balance between the use of concrete/steel treatment plants (gray infrastructure) and forested/grassland/wetland areas (green infrastructure) to protect surface water quality? The case studies compare how engineered and/or natural systems are employed to protect water quality. The conclusions drawn establish that it makes environmental, economic, and social sense to protect and manage upland forests to produce water as a downstream service. Such stewardship is far more preferable than developing land and using engineering, technology, and artificial filtration as a solution to maintaining clean drinking water. Lessons learned from this insightful study provide effective recommendations for managers and policymakers that reflect the scientific realities of how forests and engineering can be best integrated into effective watershed management programs and under what circumstances.

Описание: This book, designed as a handbook, provides a systematic treatment of analytical solutions describing groundwater flow during aquifer tests. The book integrates the majority of known solutions from well hydraulics and subsurface flow theory, starting with pioneering work from the early 20th century up to the most recent publications in scientific journals. The book includes about 300 transient solutions covering a wide range of aquifer test scenarios and hydrogeological conditions. All the solutions have been thoroughly tested and implemented in the multifunctional ANSDIMAT software. The book comprises three parts and is supplemented by appendices.The first part of the book is dedicated to basic analytical relationships referring to pumping tests with constant discharge rate. Conceptual models describe confined, unconfined, confined–unconfined, inhomogeneous, and fracture-porous aquifers, as well as leaky aquifers and multi-layer aquifer systems. Complicating factors such as flow boundaries, aquifer anisotropy, non-uniform aquifer thickness, partial well penetration, wellbore storage and skin, the effect of capillary forces are also considered.The second part focuses on complex pumping test settings and well system configurations. Analytical solutions are presented for pumping from a horizontal or inclined well, constant-head tests, multi-well variable-discharge tests, simultaneous pumping from adjacent aquifers and dipole flow tests. Detailed descriptions are given for slug and recovery tests.The third part of the book contains algorithms for evaluating hydraulic characteristics using analytical and graphical methods, and is supplemented by the ANSDIMAT tool. This software includes solutions for some practical engineering-hydrogeological problems, in particular, the assessment of aquifer characteristics by data on groundwater level monitoring and the evaluation of water inflow into open pits.The book is supplemented with appendices in which hydrogeologists can find a vast body of useful information including mathematical descriptions of the majority of analytical functions used in the book, their plots and possible approximations.Audience:The book is useful for hydrogeologists (students, engineers and researchers) engaged in groundwater flow studies, aquifer test analysis, environmental geologists and civil engineers. Experts in water flow numerical modeling and programmers developing software for aquifer tests will find valuable information in this book, which can also be used for educational and research purposes.
