Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the feasibility of using radar sensors as a remote means of detecting the presence and measuring the depth of surface water, and detecting the presence and measuring the depth to ground water. Also, previously begun studies were continued to relate radar returns, and the electrical soil constants they provided, to soil moisture content. Large laboratory soil samples were prepared at various moisture contents and with various depths of surface water and various depths to ground water. Standard pulsed radar sensors operating with frequencies of 297,5870, and 9375 mc through various angles of incidence were employed. Results indicate that the standard pulsed radar sensors can provide information to permit detection of surface water and an estimate of the moisture content of deep homogeneous soil samples. However, such sensors do not permit prediction of depth of surface water, presence of ground water, or depth to ground water. Systematic variation of surface-water depths and depths to ground water permitted an analytical solution for measuring surface- or ground-water depths, and led to the conclusion that properly designed radar systems could measure surface- and ground-water depths. Three such systems are proposed.

Book Synopsis Principles and Applications of Time Domain Electrometry in Geoenvironmental Engineering by : A.M.O. Mohamed
Download or read book Principles and Applications of Time Domain Electrometry in Geoenvironmental Engineering written by A.M.O. Mohamed and published by CRC Press. This book was released on 2006-07-27 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Time domain electrometry (TDE) is a general term which includes time domain reflectrometry and time domain transmissiometry. It is a commercially-viable technique for leak detection, contaminant monitoring, and moisture content determination in contaminant transport modelling. Under demographic pressure, contaminated sites are increasingly being re-developed for domestic and industrial use; and this presents an urgent need for reliable, non-intrusive and integrated methods of subsurface characterization, detection and monitoring of organic and inorganic pollutants, soil moisture content and salinity. This book provides an overview of the potential application of TDE in geoenvironmental engineering and describes the geophysical methods used.

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory tests were conducted with radar sensors to detect the presence of and measure the depth to subsurface interfaces when the surface was bare, and to determine the influence of vegetation at various stages of growth on radar responses. A secondary purpose was to continue earlier studies to relate radar returns and the electrical constants that they provided to moisture content and density of samples. Large laboratory samples were prepared at various moisture contents and densities and with various depths to a subsurface metal plate. Standard pulsed radar sensors operating with frequencies of 297, 5870, 9375, and 34,543 megacycles/sec and directed at various angles of incidence to the surface were employed. The results of this laboratory study indicate that the standard pulsed radar sensors can provide information that will permit an estimate of the moisture content of deep, homogeneous soil samples and the detection of surface vegetation of various heights. Radar signatures of vegetation-covered soil were more significantly altered at Ka-, X-, and C-band frequencies than at P-band frequencies. However, standard pulsed radar sensors used monochromatically cannot provide information for predicting depth to subsurface interfaces or for directly indicating the presence of a subsurface interface.
Book Synopsis Feasibility Study of the Use of Very High Frequency Radio Imaging Techniques for Detection of Tunnels (U) by : Hansjoerg J. Nikodem
Download or read book Feasibility Study of the Use of Very High Frequency Radio Imaging Techniques for Detection of Tunnels (U) written by Hansjoerg J. Nikodem and published by . This book was released on 1967 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A desk study and a laboratory scale-model study were made of the feasibility of using high resolution, very high frequency (VHF) mapping techniques to detect the presence of tunnel complexes such as occur in Vietnam. Detailed descriptions of proposed airborne systems for such detection are given. An evaluation of the feasibility of using these systems for tunnel detection was made by considering the known capabilities of existing radar systems for a similar purpose and the specific results of this scale-model study which involved the use of cylindrical and L-shaped Plexiglas rods submerged in water to simulate tunnels approximately 1 m in cross section buried beneath wet soils at depths of as much as 10 m. The results of the study indicate that tunnels could be detected in areas characteristic of a large part of Vietnam using the airborne systems described. (Author).
