This book was released on 2015 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous measurement of soil thermal conductivity, moisture content, dry density, and soil suction is a challenging issue and very important to the design of geothermal-related structures such as geothermal energy piles (GEP), ground source heat pump (GSHP) systems, borehole thermal energy storage (BTES) systems, etc. The measurement of these properties is mainly done in laboratory conditions, which can be time consuming. Hence, an attempt is made in this research to develop a new field sensor that can provide these properties in about the same timeframe. The TDR technique has been used successfully to measure soil moisture content and dry density by analyzing the soil dielectric constant (Ka) and the electrical conductivity (ECb) obtained from TDR waveforms. The objective of this research is to develop a new thermo-time domain reflectometry (TDR) probe and a moisture/suction TDR probe to better achieve these measurements. The thermo-TDR probe has three probes of the same diameter and length, with resistance wire embedded in the center probe, and three thermocouples installed in each probe. The probe calibrations for Ka and ECb were completed by testing five different chemicals with known Ka values, and NaCl and KCl solutions with different concentrations. The probe was then evaluated by testing four different materials, i.e., three sands and kaolin clay, and validating them against the KD2 standard probe for measurement of soil thermal properties. Laboratory experiments employing the thermo-TDR probe were then performed on quartz sands, sand-sand mixtures, and sand-clay mixtures to study the effects of the quartz content, particle size, moisture content, dry density, and clay content on soil thermal conductivity. Based on the experimental results on sand-clay mixtures, a continuum soil thermal conductivity prediction model was developed. The model overcame the shortcomings of the existing models, which accounts for the quartz content effect and prediction of soil thermal conductivity continuously over the entire range of soil types. The moisture/suction TDR probe has two steel stainless probes and a gypsum block attached to half of the probes. The calibration of the probe is conducted by modified pressure plate tests to establish the relationship between Ka and the matric suction of the gypsum block. Laboratory experiments on silty sand, including the staged-drying test and absorption and desorption tests, were performed to evaluate the probe and to study the equilibrium or response time of the gypsum block being equilibrated with surrounding soils

Download or read book Applications of Soil Physics written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.

Book excerpt: This innovative study presents concepts and problems in soil physics, and provides solutions using original computer programs. It provides a close examination of physical environments of soil, including an analysis of the movement of heat, water and gases. The authors employ the programminglanguage Python, which is now widely used for numerical problem solving in the sciences. In contrast to the majority of the literature on soil physics, this text focuses on solving, not deriving, differential equations for transport. Using numerical procedures to solve differential equations allowsthe solution of quite difficult problems with fairly simple mathematical tools. Numerical methods convert differential into algebraic equations, which can be solved using conventional methods of linear algebra. Each chapter introduces a soil physics concept, and proceeds to develop computer programsto solve the equations and illustrate the points made in the discussion.Problems at the end of each chapter help the reader practise using the concepts introduced. The text is suitable for advanced undergraduates, graduates and researchers of soil physics. It employs an open source philosophy where computer code is presented, explained and discussed, and provides thereader with a full understanding of the solutions. Once mastered, the code can be adapted and expanded for the user's own models, fostering further developments. The Python tools provide a simple syntax, Object Oriented Programming techniques, powerful mathematical and numerical tools, and a userfriendly environment.
