Download or read book Measurement of Hydraulic Conductivity in Clay Using Push In Piezometers written by DJ. DeGroot and published by . This book was released on 1992 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydraulic performance of push-in standpipe piezometers was evaluated at a site consisting of medium stiff and soft varved clay in western Massachusetts. The results of falling head hydraulic conductivity tests performed in the piezometers were compared with results of tests performed in prebored and sand-packed piezometers and laboratory flexible wall tests performed on undisturbed samples obtained at the site. A comparison of the field and laboratory tests conducted throughout the upper portion of the profile indicates that while tests performed in the prebored piezometers generally gave hydraulic conductivity results higher than laboratory tests, results from tests performed in push-in piezometers were closer to laboratory tests.

Download or read book A Comparison Between Field and Laboratory Measurements of Hydraulic Conductivity in a Varved Clay written by DJ. DeGroot and published by . This book was released on 1994 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of hydraulic conductivity using a variety of field and laboratory techniques was evaluated at a site consisting of medium stiff and soft lacustrine varved clay in western Massachusetts. Field measurements were obtained by conducting "slug" tests in both predrilled and push-in piezometers and also from pore pressure dissipation tests using the piezocone and flat dilatometer. Laboratory hydraulic conductivity values were obtained for both vertical and horizontal flow conditions using a flexible wall permeameter and by indirect estimation from 1-dimensional consolidation tests. Based on a comparison of tests conducted throughout the profile, laboratory flexible wall tests with vertical flow gave the lowest values of hydraulic conductivity whereas the predrilled piezometers yielded the highest values. Of all the field techniques, the push-in piezometers gave the lowest values. Hydraulic conductivity values interpreted from piezocone and flat dilatometer dissipation tests tended to be between those obtained from the predrilled and push-in piezometers. Results from tests in predrilled piezometers show that the hydraulic conductivity increases with increasing screen length, showing the influence of scale effects. The results of this study clearly show that estimation of hydraulic conductivity for this soil is highly dependent on scale effects, the test technique used and on the direction of flow (i.e., parallel versus perpendicular to the orientation of the varves).

Available in PDF, EPUB and Kindle. Book excerpt: A thoroughly updated classic on the fundamentals of groundwater The second edition of Fundamentals of Groundwater delivers an expert discussion of the fundamentals of groundwater in the hydrologic cycle and applications to contemporary problems in hydrogeology. The theme of the book is groundwater, broadly defined, and it covers the theory and practice of groundwater—from basic principles of physical and chemical hydrogeology to their application in traditional and emerging areas of practice. This new edition contains extensive revisions, including new discussions of human impacts on aquifers, and strategies and concepts for sustainable development of groundwater. It also covers the theory of groundwater flow—including concepts of hydraulic head and the Darcy equation—and ground water/surface water interactions, as well as geochemistry and contamination. Readers will also find A thorough introduction to the techniques of water resource investigations and regional groundwater flow Comprehensive explorations of groundwater chemistry and its applications in regional characterization and assessments of health impacts Practical discussions of groundwater contamination and water sustainability more generally Fulsome treatments of newly emerged contaminants, like PFAS, pathogens, agricultural contaminants, methane, arsenic, uranium, and redox processes Perfect for undergraduate and graduate students taking courses in hydrogeology, groundwater, geoscience, applied geoscience, and groundwater and contaminant processes, Fundamentals of Groundwater also benefits environmental consultants, geochemists, engineers, and geologists.

Download or read book Advances in Understanding Engineered Clay Barriers written by Eduardo E. Alonso and published by CRC Press. This book was released on 2005-06-23 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of clay barriers for waste-isolating purposes has gained increasing attention in the geotechnical engineering community. Practical interest is linked to fundamental research, which includes examination of the behaviour of compacted materials and expansive clays. The interaction between the barrier, waste and the surrounding ground may involve several thermo-hydro-mechanical and chemical-coupled processes that have been analyzed by means of 'in situ' tests, laboratory experiments and numerical modelling. Large-scale field tests have been developed in recent years by European Agencies dealing with the management of radioactive waste. These experiments have provided an opportunity to calibrate and to validate research models and offer benefits in terms of experience of instrumentation and installation techniques. The book includes about sixty papers presented in a symposium held in Spain in 2003. The four main topics of the book are: field emplacement and instrumentation techniques; fundamental research, material behaviour (i.e. bentonite), and laboratory testing; barrier behaviour and THM modelling; and chemical effects, HC and THMC modelling.
