Measurement System for Soil-Air Permeability Coefficient in Soil Deodorizer

Estimation of Soil Permeability using Soil Index Properties

Permeability is a very important engineering property of soils and finds utility in a number of soil engineering problems such as yield of wells and seepage through and below the earth structures. It controls the hydraulic stability of soil masses. The permeability of soils is also required in the design of filters required to prevent piping in hydraulic structures. However, the determination o...

VARIATION IN SOil WATER AND SOil AIR CONTENTS ASSOCIATED WITH A VEGETATION - SOil SEQUENCE IN

SU.M~IARY: This paper describes part of a study of vegetation/soil system dynamics in which d~e re]ationships were demonstrated bctween structuraJ chang<' of the forest, with"associated changes in composition, and changes in otganic matter and soil physical properties, particularly the quantities cf water and air in non-capillarypores. Becausc of these rcsults an a.nalysis,\','as made of the qu...

Measurement Technologies for Radon in the Soil

Although the principal means to confirm indoor radon involves testing buildings, soil-based investigations are of value in identifying land areas that pose special concerns. Ideally, soil-based measurements would relate to radon production, diffusive transport, and convective transport into buildings. This paper briefly reviews technologies for measuring radon in soil gas, radon flux, and soil ...

A TDR-Based Soil Moisture Monitoring System with Simultaneous Measurement of Soil Temperature and Electrical Conductivity

Elements of design and a field application of a TDR-based soil moisture and electrical conductivity monitoring system are described with detailed presentation of the time delay units with a resolution of 10 ps. Other issues discussed include the temperature correction of the applied time delay units, battery supply characteristics and the measurement results from one of the installed ground mea...
