Book excerpt: Bachelor Thesis from the year 2016 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 3.91, , course: Geology/Mining Technology, language: English, abstract: The Vertical Electrical Sounding (VES) technique was carried out in Alode Community of Eleme Local Government Area in Rivers State to determine the geo-electrical and hydrogeological characteristics of the aquifers present in the area, and to delineate the geo-electric stratigraphy of each VES station. A total of three (3) VES were carried out with the ABEM Terrameter SAS 300C, using the Schlumberger Configuration. Maximum half-current electrode spread (AB/2) of 1m up to 150m was used, while the half potential electrode separation (MN/2) was maintained between 0.5m and 7.5m. The VES curves were quantitatively interpreted by partial curve matching and computer iteration techniques, using the IP1 WIN computer software. The results of the interpreted VES data confirm the following stratigraphies: top soil (40.2-65.2Ωm), shale (32.2-86.3Ωm), fine-medium sand (172-204Ωm), medium-coarse sand (532Ωm), and medium sand (417Ωm). Geo-electric sections reveal that the aquiferous units are mostly confined, with depth to aquifer range of 47m for VES 1 and 2 and 21m for VES 3.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The integrated use of Electromagnetic Ground Conductivity, Ground Electrical Resistivity and Seismic Refraction geophysics methods was made in Alia valley, Eritrea for the aim of developing a methodology best suited for ground water exploration in hard rock areas with limited professional and financial resources. A total area of 25 square kilometer was covered with the geophysical surveys. The effective use of information from wells and geological information from outcrops and existing literature helped to create a preliminary conceptual hydrogeologic model that in turn provided a general picture of the research site in terms of its groundwater potential and related factors. The optimum configuration of the geophysical methods and their interpretation was researched by the use of synthetic mathematical models and experimental surveys in areas of known hydrogeological characteristics like lithology and depth of water table. Two approximately parallel electromagnetic ground conductivity profile lines crossed the survey area in approximately north-south direction to assess the variation in the electrical conductivity of the major geological structures. Vertical electrical sounding (VES) surveys were conducted close to existing wells with lithological information and at some selected sites. Survey sites for the two dimensional electrical resistivity imaging and the seismic refraction surveys were selected based on the results from the electromagnetic ground conductivity surveys. The formal geophysical surveys results were correlated with nearby boreholes and with each other. The responses of the different geophysical methods for each lithological layer were recognized. In addition, the location and characteristics of the major geological structures of the area were studies based on the information from the geophysical surveys and other available information. At the end of the research, parts of the research area with better groundwater potential were identified. As a result of the research, an efficient and cost effective geophysical approach was developed for groundwater exploration in hard rock areas of Eritrea and similar places of the world. Recommendations were made on the wider and effective use of the approach with due consideration for the limited financial, human resource and material capacities available for ground water exploration in most countries of Africa and other countries of the world.
Download or read book Groundwater Geophysics in Hard Rock written by Prabhat Chandra Chandra and published by CRC Press. This book was released on 2015-09-01 with total page 0 pages. 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 of time, something that could have been avoided by a systematic and proper geophysical approach. The combination of various geophysical techniques with environmental conditions is essential to constrain the interpretation and reduce uncertainties in this respect. This book presents the approach to groundwater exploration in hard rocks, various geophysical techniques and combinations to be used, interpretation of data with case studies and drilling results and the preparation of different utility maps.

Download or read book An Introduction to Geophysical Exploration written by Philip Kearey and published by John Wiley & Sons. This book was released on 2013-04-16 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition of the well-established Kearey and Brooks text is fully updated to reflect the important developments in geophysical methods since the production of the previous edition. The broad scope of previous editions is maintained, with even greater clarity of explanations from the revised text and extensively revised figures. Each of the major geophysical methods is treated systematically developing the theory behind the method and detailing the instrumentation, field data acquisition techniques, data processing and interpretation methods. The practical application of each method to such diverse exploration applications as petroleum, groundwater, engineering, environmental and forensic is shown by case histories. The mathematics required in order to understand the text is purposely kept to a minimum, so the book is suitable for courses taken in geophysics by all undergraduate students. It will also be of use to postgraduate students who might wish to include geophysics in their studies and to all professional geologists who wish to discover the breadth of the subject in connection with their own work.
