Available in PDF, EPUB and Kindle. Book excerpt: Lateral changes in geology pose a serious problem in data interpretation for any surface geophysical method. Although many geophysical techniques are designed to probe vertically, the source signal invariably spreads laterally, so any lateral variations in geology will affect the measurements and interpretation. This problem is particularly acute for controlled source electromagnetic soundings because only a few techniques are available to interpret the data if lateral effects are present. In this thesis we examine the effects of geological contacts for the time domain electromagnetic sounding method (TDEM). Using two simple two-dimensional models, the truncated thin-sheet and the quarter-space, we examine the system response for several commonly used TDEM sounding configurations. For each system we determine the sensitivity to the contact, establish how to the contact anomaly may be distinguished from other anomalies and, when feasible, develop methods for interpreting the contact geometry and for stripping the contact anomaly from the observed data. Since no numerical models were available when this work was started, data were collected using scale models with a system designed at the University of California at Berkeley. The models were assembled within a table-top modeling tank from sheets or blocks of metal using air or mercury as a host medium. Data were collected with a computer-controlled acquisition system.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of time-domain electromagnetic (TDEM) soundings were made in the vicinity of Medicine Lake, California, during July, 1982, as part of the US Geological Survey's geothermal research program. The objectives were to evaluate the use of TDEM methods in this environment, to compare frequency and time-domain results, and to study variations in the conductive layer (Zohdy and Bisdorf, 1982) which were known to exist in the area of the Medicine Lake volcano. The TDEM soundings were made at nine sites using both single and central loop configurations (Spies, 1980). At several of the sites, the large TDEM square loop (1500 ft. per side) was also used as a transmitter loop for loop-loop frequency domain soundings (Frischknecht, 1967). The frequency domain soundings have not been processed to-date; however, to make the data available, all TDEM results and their computer inversions are being presented in this preliminary report.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of techniques that are available to characterize sedimentary aquifers. Groundwater flow and solute transport are strongly affected by aquifer heterogeneity. Improved aquifer characterization can allow for a better conceptual understanding of aquifer systems, which can lead to more accurate groundwater models and successful water management solutions, such as contaminant remediation and managed aquifer recharge systems. This book has an applied perspective in that it considers the practicality of techniques for actual groundwater management and development projects in terms of costs, technical resources and expertise required, and investigation time. A discussion of the geological causes, types, and scales of aquifer heterogeneity is first provided. Aquifer characterization methods are then discussed, followed by chapters on data upscaling, groundwater modelling, and geostatistics. This book is a must for every practitioner, graduate student, or researcher dealing with aquifer characterization .
