Available in PDF, EPUB and Kindle. Book excerpt: The self-potential method enables non-intrusive assessment and imaging of disturbances in electrical currents of conductive subsurface materials. It has an increasing number of applications, from mapping fluid flow in the subsurface of the Earth to detecting preferential flow paths in earth dams and embankments. This book provides the first full overview of the fundamental concepts of this method and its applications in the field. It discusses the historical perspective, laboratory investigations undertaken, the inverse problem and seismoelectric coupling, and concludes with the application of the self-potential method to geohazards, water resources and hydrothermal systems. Chapter exercises, online datasets and analytical software enable the reader to put the theory into practice. This book is a key reference for academic researchers and professionals working in the areas of geophysics, environmental science, hydrology and geotechnical engineering. It will also be valuable reading for related graduate courses.

Corwin and published by . This book was released on 1989 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report consists of four distinct but complementary parts: a laboratory/field study of environmental effects on self-potential (SP) electrodes and long-term stability of the electrodes; field investigations at Beaver Dam, Arkansas; development of a computer program for interpreting seepage-related SP field survey data; and development of an extensive bibliography and database for acquisition and interpretation of seepage-related SP data. The geotechnical problem at the Beaver Dam, AR, site was anomalous underseepage in the foundation of a large embankment dike. SP data were effectively used to map the seepage paths. Three electrodes were investigated: non-polarizing copper-copper sulfate (CS), copper-clad steel (CCS), and lead. Of the three, the commercial-grade lead electrodes are least suitable for long-term monitoring of SP. CS electrodes with gelled electrolyte appear capable of surviving at least a few years without maintenance or significant deterioration of physical properties or performance. For SP measurements, CCS electrodes have a lower signal to noise ratio than do CS electrodes. Field and laboratory measurements indicate that responses of CCS electrodes to environmental disturbances are an order of magnitude or greater than CS electrodes. The higher noise level is due both to the direct exposure of the metal to the soil as well as the exposure of the unburied portion of the electrodes to solar heating and rainfall. Thus, the considerably higher initial cost and extra effort involved in installation of the CS electrodes are justified, and CS electrodes are recommended for geotechnical applications of the SP method.

Erchul and published by . This book was released on 1988 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self potential (SP) measurements were effectively used in the detection of surface and subsurface drainage around a sinkhole. The same SP technique was also able to track an apparent subsurface flow path for over 600 ft from one sinkhole into another sinkhole. Confirmation of the SP data was obtained by visual observation, electrical resistivity measurements and geological studies. The use of this geophysical technique was evaluated in and around sinkholes in a karst area of west central Virginia. The SP electrode configuration consisted of a double ring of electrodes circumferentially located around each sinkhole. Two reference electrodes were used in taking SP measurements. One reference electrode was located outside the rings of electrodes, and the other was located in the center of one of the sinkholes. Once a major drainage path around the sinkhole was detected, an array of electrodes was used to track the flow path. Although SP data varied significantly for individual electrodes during the 6-month testing period, the relative values between electrodes were consistent. This finding was also true if the position of the reference electrode was changed. It appeared that changes in precipitation and temperature had a great effect on the variation of SP data over the testing period. Keywords: Subsurface drainage; Surface drainage.

Wilt and published by . This book was released on 1990 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual describes the theory and operations of program SPPC. This code, a microcomputer (PC) version of program SPXCPL, calculates the self potential anomaly due to fluid and thermal sources in geologic media. Fluid and heat flow generate significant electrical potentials due to cross-coupling between fluid and heat flow and the flow of electrical current. The SP anomalies are largest near the primary flow sources and in regions where the cross-coupling coefficients change (geological boundaries). Program SPPC allows for the forward model calculation of primary potential (pressure or temperature) and secondary potential (voltage) for discrete sources of heat or pressure in a two-dimensional model of the earth. Input for the program involves a small mesh where values are assigned for permeability or thermal conductivity, cross-coupling coefficients, and electrical resistivity. Magnitude and location of the primary sources (fluid or heat flow) must also be specified. The output file provides values for the primary potential and voltage on the surface and throughout the two-dimensional model. The manual provides a discussion of the input parameters, a section on how to read the output, and some guidance on applying the program to physical problems. The program was validated with an analytical solution for a point pressure source in a homogeneous halfspace. A field example is shown where SP data collected near a leaky dam site is used to locate the zone of leakage. The potential users of program SPPC is urged to read report 3, ADA 207704, in this series for guidance on obtaining the required modeling parameters. (edc).

Available in PDF, EPUB and Kindle. Book excerpt: In hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste
