Geophysics

In this book, the different types of geophysical logs and equipment used in hydrogeologic investigations are reviewed. Applications and analysis methods are illustrated by specific examples in both unconsolidated deposits and bedrock settings.

In this book, we outline the theory and application of electrical imaging methods, which inject current into the ground and measure the resultant potentials.

This book summarizes the theory and examples of the use of Distributed Temperature Sensing (DTS), Distributed Strain Sensing and Distributed Acoustic Sensing (DAS) for subsurface characterization and analysis of groundwater/surface water exchange.
