Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to broaden and improve aquifer test analysis by generating type curves for complicated aquifer and well conditions. It simplifies type curve matching with on-screen interactive techniques, and introduces a statistical semi-automatic protocol for calibrating aquifer test site models. In addition, it discusses the validity of aquifer test analysis results. For anyone involved in aquifers and wells, this is an excellent resource for testing and analysis.
Download or read book Climate Change and Groundwater Planning and Adaptations for a Changing and Uncertain Future written by Robert Maliva and published by Springer Nature. This book was released on 2021-01-26 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to bridge the gap between the climate change research and decision-making communities by exploring the impacts of climate change on groundwater from a more applied perspective. Global climate change will impact groundwater demands, quality, and available supplies, and rising sea level may cause water tables to rise, inundating low-lying coastal areas. Groundwater will increasingly be needed to perform a stabilization role in mitigating fluctuations in the supply of surface waters, serving as a buffer against droughts. Climate change has become a frequent subject in the mass media, and the academic literature on the subject is now enormous. An impediment to climate change adaptation with respect to water is a poor link between the climate change research community and the actual decision-makers responsible for water supply planning. Key issues explored are methods for evaluating potential impacts on climate change on local groundwater systems, the adaptation of decision-making process, and how climate change adaptation can be mainstreamed into the water supply planning.
Download or read book Hydrogeological Conceptual Site Models written by Neven Kresic and published by CRC Press. This book was released on 2012-07-30 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: A reference for students, researchers, and environmental professionals, Hydrogeological Conceptual Site Models: Data Analysis and Visualization explains how to develop effective conceptual site models, perform advanced spatial data analysis, and generate informative graphics for applications in hydrogeology and groundwater remediation. Written by expert practitioners, this full-color book illustrates how fundamental hydrogeological concepts are translated into quantitative, high-resolution computer visualizations. In addition, the authors discuss topics not typically covered in conventional textbooks, including GIS technology and the relationship between conceptual site models and environmental policy. Advanced Methods for Data Analysis and Visualization Featuring more than 500 color illustrations, this unique and visually powerful book outlines the required elements of a conceptual site model and provides numerous examples of supporting charts, cross-sections, maps, and 3D graphics. The authors describe advanced analytical methods such as geospatial processing, kriging, and groundwater modeling through practical real-life examples. They also present numerous case studies in groundwater supply and remediation to help explain key engineering design concepts. Data-Driven Assessments of Groundwater Management Policy The authors tackle controversial topics, ranging from technical impracticability of groundwater remediation to sustainable management of groundwater resources. They encourage discussion and independent thought about how current environmental policies and practices can evolve to achieve better outcomes at less cost to society. Practical Strategies for Communicating Your Findings to the General Public While the book is technical in nature, equations and advanced theory are kept to a minimum. The text focuses on practical strategies to help you create easy-to-understand data tables, graphs, maps, and illustrations for technical and nontechnical audiences alike. A companion DVD includes animations, reference material, modeling software, and more.

Download or read book Characterizing Groundwater Recharge written by J. Moran and published by IWA Publishing. This book was released on 2004-01-01 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the project was to demonstrate the value of age-dating and isotopic tracers in characterizing the flow dynamics and water quality changes in a complex groundwater domain that includes high capacity municipal pumping wells, a geologic fault, and artificial recharge facilities with deep lake-like recharge ponds. Characterizing water quality changes during recharge and transport in groundwater was also an objective of this investigation. Below (west of) the Hayward Fault (BHF), water ages correlated well with aquifer layer sequence. BHF tracers did not reach the BHF wellfield within the time frame of the experiment. Above (east of) the fault, (AHF) tracers reached the targeted wellfield in only 60 days, indicating substantial heterogeneity and a fast travel time along preferential pathways compared to the average travel time of 2+ years indicated by age-dating and more classical estimating methods. A reconnaissance of water quality, conducted concurrently with the tracer studies, suggested certain water quality improvements occurring in either the pond sediment or the near-pond aquifer media. Variations in groundwater age depended on location and depth. A survey of natural isotopes indicated mixing of young and older water in wells, increasing age with depth of aquifer layer, and possible dissolution of carbonate minerals. AHF tracer experiments, along with other analysis, suggested that tracers probably percolated preferentially at shallow depths in the pond near the shoreline. Much of the tracer remained in deep pond water over time, increasing residence time in down-gradient wells. The tracer studies provided evidence of preferential pathways and heterogeneity in the AHF aquifer and a fast minimum travel time to the AHF wellfield. The tracer added to BHF ponds was detected in just two monitoring wells, but not at the BHF wellfield over the 10-month period. An AHF tracer from a small pond spanning the fault did, however, appear at the BHF wellfield. BHF pond water flows mainly to distal portions of the groundwater basin, or reaches the wellfield over a slow, circuitous route.
