Features

• Clear guide on the interpretation and use of geophysical research data, useful for application in groundwater monitoring and movement, relevant for well-boring and construction of large civil works.
• Aims for convergence of hydrogeological, hydrochemical and geophysical approaches; numerous case studies will guide in the application of different tools to solve problems related with water resources.
• Presents a complete overview of current data interpretation techniques; includes case studies on different hard rock formations.
• Effectively integrates geophysical techniques to minimize uncertainty and therefore boring failure; may lead to acceptance of well-defined and relatively cheap geophysical investigations, compared with other prospecting tools.

• No comparable books on hard rock geophysics are available; author is an expert in the field.

Summary

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.
