Introduction to geophysical methods

Geophysics is a discipline based on the measurement of physical parameters of the subsoil, the development of mathematical filters has allowed to interpret this type of data with greater precision. Theoretical modelling applied to geophysical data allows to define the adequate parameters for each type of geological structure, the applications of potential field methods are very diverse as an indication in mining prospecting, oil exploration and karst hydrogeology, etc. Sub-surface geophysics contributes to the improvement of daily life by assessing and predicting the risk of geotechnical problems such as karst collapse, landslides, water rising and pollution. In this document the theoretical aspect of each method is discussed so that the reader will have a preliminary idea of the theoretical concepts, the modalities of data acquisition, processing and finally the interpretation. At the end of each chapter a practical example is explained in order to better understand the fundamental concepts of each method.
