Available in PDF, EPUB and Kindle. Book excerpt: Interpretation and reliability of in situ tests, such as cone penetration, can be improved if in situ moisture content and density can be measured without affecting the speed of site investigation significantly. This paper describes the principle and technique of determining moisture content with a penetrometer that can measure the dielectric constant (specific inductive capacitance) of soils. Effects of various factors, such as salt content of water, on the measured parameter are discussed with special reference to frequency of the measuring bridge. This study shows that it is possible to determine the in situ moisture content of soils from measurements conducted at very high frequencies. This method presents particular promise because the moisture content versus capacitance relationship has been found to be practically independent of soil type.

This book was released on 2018-04-13 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: RILEM TC 248-MMB was established in 2012 with the main aim to improve and distribute knowledge related to moisture measurement in construction materials in various scientific and industrial applications. Properties and performance of building materials and structures are influenced to a large extent by the moisture conditions in the materials. Obvious examples are heat conductivity, shrinkage and creep, transport properties, most types of deterioration, discoloration etc. For research and applications the moisture conditions must be quantified, by measurements in the laboratory or under field conditions. There is much variation in methods being used, even within the same topic, in different countries, both with regard to materials and to applications. No consensus whatsoever does exist. For the construction industry it is important to be able to quantify the moisture conditions in an accurate way in various applications. This state-of-the-art report is divided into two parts, Principles and Applications, with altogether 28 chapters on various moisture measuring principles and a number of applications.
Download or read book Soil Moisture Measurement Classic Reprint written by Howard W. Lull and published by Forgotten Books. This book was released on 2018-03-18 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil-Moisture Measurement As has been noted, the gravimetric method is the only commonly used direct means of measuring soil moisture. Simply, it involves taking a soil sample, weighing it, oven-drying it, reweighing, and expressing the original moisture content in percent of oven-dry weight of soil. The first step, securing the sample, is the most troublesome, the degree of difficulty depending on the condition of the soil. Sampling conditions are ideal when soil is just moist enough for easy ingress and egress of the sampling instrument, and where stones, roots, and organic matter are not a problem. Such conditions are seldom encountered. With free water in the soil, moisture can never be sampled accurately: water will drip off as the sample is removed from the ground or compaction may squeeze it out. Rapid sampling is essential to prevent undue losses. Stickiness, often a problem in wet soils, can be alleviated by keeping instruments clean. Where a wet layer overlies a dry one, samples taken from the drier levels may be contaminated. After the upper soil is wetted by a summer rain, for instance, removal of a sample may permit water to run down the hole toward drier soil. The same problem is en countered when samples are taken below a perched water table. Wet instruments add to contamination and should be dried between samplings. When the soil is dry and hard, the principal problem in fine textured soils is to get the sampling instrument in and out again. In coarse-textured soils particularly, samples may slide out of the in strument as it is withdrawn from the soil. Fortunately, after the soil dries in summer, its moisture content may fluctuate so little that frequent sampling may be unnecessary.

Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.
