Download or read book Hydraulic Conductivity written by Lakshmanan Elango and published by BoD – Books on Demand. This book was released on 2011-11-23 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several books on broad aspects of hydrogeology, groundwater hydrology and geohydrology, which do not discuss in detail on the intrigues of hydraulic conductivity elaborately. However, this book on Hydraulic Conductivity presents comprehensive reviews of new measurements and numerical techniques for estimating hydraulic conductivity. This is achieved by the chapters written by various experts in this field of research into a number of clustered themes covering different aspects of hydraulic conductivity. The sections in the book are: Hydraulic conductivity and its importance, Hydraulic conductivity and plant systems, Determination by mathematical and laboratory methods, Determination by field techniques and Modelling and hydraulic conductivity. Each of these sections of the book includes chapters highlighting the salient aspects and most of these chapters explain the facts with the help of some case studies. Thus this book has a good mix of chapters dealing with various and vital aspects of hydraulic conductivity from various authors of different countries.

Download or read book In situ Permeability Measurements with the Cone Permeameter trademark Measurement System written by and published by . This book was released on 1998 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The permeability of soil to fluid flow defines the magnitude of soil gas and groundwater flow under imposed pressure gradients. Pressure gradients exist due to natural effects such as hydraulic gradients (in the case of groundwater) and barometrically imposed gradients (in the case of soil gas). Unnatural gradients are imposed by soil vapor extraction air sparging, active venting, pump-and-treat, and other remediation processes requiring the active movement of fluids through the soil. The design of these processes requires knowledge of the flow characteristics of the soil. The most variable of the soil's flow characteristics is its permeability, which can vary by several orders of magnitude in a given geologic and hydrologic setting. Knowledge of soil gas permeability is needed to design soil vapor extraction systems and predict the general movement of gas in soil. Saturated hydraulic conductivity, or the soil's permeability to liquid flow, is required to predict movement of groundwater in saturated soils. The variability of permeability is illustrated by the range of values for different media in a table. It is not uncommon for permeabilities to vary by several orders of magnitude at a given site.

Download or read book Hydraulic Conductivity Measurement in Unsaturated Soils with a Modified Cone Penetrometer written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project, a new cone penetration test (CPT) method for the determining the hydraulic properties of unsaturated soil was developed. A modified cone penetrometer (cone permeameter) is used to inject water into the soil under constant pressure through a screen and measure movement of the wetting front with tensiometer rings. An inverse methodology is used to analyze the cumulative inflow volume and pressure head readings to obtain estimates of the hydraulic conductivity and soil moisture retention curves for the soil. To accomplish the inversion, a cone permeameter test is numerically simulated with the radially symmetric form of Richard's equation and the van Genuchten hydraulic conductivity and moisture retention functions. An objective function expressing the differences between flow responses measured with the cone permeameter and those predicted using the numerical model with the parameterized soil hydraulic properties is minimized to obtain the hydraulic parameter estimates. Full scale tests in a laboratory aquifer and field tests were performed during the course of this study. Excellent agreement between saturated hydraulic conductivity values obtained with the cone permeameter and values from in-situ Guelph permeameter and laboratory falling head tests was obtained. Soil moisture retention curves were similar to those obtained from multi-step outflow and capillary rise tests.

Download or read book Soil Physical Measurement and Interpretation for Land Evaluation written by Keppel Coughlan and published by CSIRO PUBLISHING. This book was released on 2002-11-26 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil physical measurements are essential for solving many natural resource management problems. This operational laboratory and field handbook provides, for the first time, a standard set of methods that are cost-effective and well suited to land resource survey. It provides: *practical guidelines on the soil physical measurements across a range of soils, climates and land uses; *straightforward descriptions for each method (including common pitfalls) that can be applied by people with a rudimentary knowledge of soil physics, and *guidelines on the interpretation of results and integration with land resource assessment. Soil Physical Measurement And Interpretation for Land Evaluation begins with an introduction to land evaluation and then outlines procedures for field sampling. Twenty detailed chapters cover pore space relations, water retention, hydraulic conductivity, water table depth, dispersion, aggregation, particle size, shrinkage, Atterburg limits and strength. The book includes procedures for estimating soil physical properties from more readily available data and shows how soil physical data can be integrated into land planning and management decisions.
