Available in PDF, EPUB and Kindle. Book excerpt: GeoMeasurements by Pulsing TDR Cables and Probes examines Time Domain Reflectometry (TDR) research and provides information on its use as a robust, reliable, and economical production tool. Common uses for TDR technology include telecommunications and power industries, but the text examines applications such as measurement of moisture of unsaturated soils; detection of fluids for leak and pollution; measurement of water levels for hydrological purposes; measurement of water pressures beneath dams; and deformation and stability monitoring of mines, slopes, and structures. Chapters discuss: basic physics of signal generation, transmission, and attenuation along the coaxial cable probe designs and procedures for calibration as well as the variation in probe responses to changes in water content and soil mineralogy variations in waveform characteristics associated with cable, deformation, cable calibration, and installation techniques for metallic cables in rock several cases demonstrating the use of TDR cables in soil as well as weathered and soft rock a rationale for the use of compliant cable in soil the use of metallic cable (MTDR) and optical fiber (OTDR) to monitor response of structures sensor/transducer components, connections from the sensors to the TDR pulser/sampler, and system control methods available software for transmission and analysis of TDR signatures The diverse interest and terminology within the TDR community tends to obscure commonalities and the universal physical principles underlying the technology. The authors seek to crystallize the basic principles among the seemingly divergent specialties using TDR technology in geomaterials. By examining varied experiences, GeoMeasurements by Pulsing TDR Cables and Probes provides a synergistic text necessary to unify the field.

Download or read book New Pesticides and Soil Sensors written by Alexandru Mihai Grumezescu and published by Academic Press. This book was released on 2017-02-10 with total page 794 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Pesticides and Soil Sensors, a volume in the Nanotechnology in the Agri-Food Industry series, is a practical resource that demonstrates how nanotechnology is a highly attractive tool that offers new options for the formulation of 'nanopesticides'. Recent advances in nanopesticide research is reviewed and divided into several themes, including improvement of the water solubility of poorly soluble pesticide active ingredients to improve bioavailability and the encapsulation of pesticide active ingredients within permeable nanoparticles with the aim of releasing pesticide active ingredients in a controlled or targeted manner, while also protecting active ingredients from premature photo-degradation. - Provides examples of pesticide formulations that contain inorganic and organic nanoparticles - Includes general principles and the most recent applications of chemical sensors and multisensory systems for the assessment of soils and main soil nutrition component detection - Presents the main benefits and drawbacks of chemical sensors and their employment in soil analysis for further applications - Describes current issues of pesticide use, environmental contamination, bioaccumulation, and increases in pest resistance which demands a reduction in the quantity of pesticides applied for crop and stored product protection
Download or read book Unsaturated Soils Two Volume Set written by Eduardo E. Alonso and published by CRC Press. This book was released on 2010-09-02 with total page 1532 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades the development of unsaturated soil mechanics has been remarkable, resulting in momentous advances in fundamental knowledge, testing techniques, computational procedures, prediction methodologies and geotechnical practice. The advances have spanned the full spectrum of theory and practice. In addition, unsaturated materials exhibiting complex behaviour such as residual soils, swelling soils, compacted soils, collapsing soils, tropical soils and solid wastes have been integrated in a common understanding of shared behaviour features. It is also noteworthy that unsaturated soil mechanics has proved surprisingly fruitful in expanding to other neighbouring areas such as swelling rocks, rockfill mechanics, and freezing soils. As a consequence, geotechnical engineering involving unsaturated soils can be now approached from a more rational and systematic perspective leading towards an improved and more effective practice. Unsaturated Soils contains the papers presented at the 5th International Conference on Unsaturated Soil (Barcelona, Spain, 6-8 September 2010). They report significant advances in the areas of unsaturated soil behaviour, testing techniques, constitutive and numerical modelling and applications. The areas of application include soil-atmosphere interaction, foundations, slopes, embankments, pavements, geoenviromental problems and emerging topics. They are complemented by three keynote lectures and three general reports covering general issues of modelling, testing and applications. Unsaturated Soils is a comprehensive record of the state-of-the art in unsaturated soil mechanics and a sound basis for further progress in the future. The two volumes will serve as an essential reference for academics, researchers and practitioners interested in unsaturated soils.

Download or read book Surface Water Balance for Recharge Estimation Part 9 written by L Zhang and published by CSIRO PUBLISHING. This book was released on 2002-10-09 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This addition to The Basics of Recharge and Discharge series deals with the surface water balance approaches that form the traditional basis of hydrological investigations. It explores both field methods and modelling methods for measuring or estimating the different parts of the water balance, including rainfall, evaporation, run-off and soil water storage. The authors discuss the concepts required to understand a surface water balance result or to set up an experiment. As water balance studies can be both time-consuming and expensive, this report will give readers a better understanding of water balance approaches and the considerations before going into a water balance study for the purpose of deep drainage.

This quadrennial conference is the traditional focal point for the physical modelling community of academics, scientists and engineers to present and exchange the latest developments on a wide range of physical modelling aspects associated with geotechnical engineering. These proceedings, together with the seven previous proceedings dating from 1988, present an inestimable collection of the technical and scientific developments and breakthroughs established over the last 25 years. These proceedings include 10 keynote lectures from scientific leaders within the physical modelling community and 160 peer-reviewed papers from 26 countries. They are organised in 14 themes, presenting the latest developments in physical modelling technology, modelling techniques and sensors, through a wide range of soil-structure interaction problems, including shallow and deep foundations, offshore geotechnics, dams and embankments, excavations and retaining structures and slope stability. Fundamental aspects of earthquake engineering, geohazards, ground reinforcements and improvements, and soil properties and behaviour are also covered, demonstrating the increasing complexity of modelling arising from state-of-the-art technological developments and increased understanding of similitude principles. A special theme on education presents the latest developments in the use of physical modelling techniques for instructing undergraduate and postgraduate students in geotechnical engineering.
