EEGU introduces nontraditional geophysical conference attendees (regulators, environmental program managers, consultants, and students who are new to near-surface geophysics) to incorporating geophysical approaches into characterization or remediation programs or to evaluating the suitability of geophysical methods for general classes of environmental or engineering problems. In the 20th century, geophysical methods were developed for remote exploration of the solid Earth and the ocean, and geophysics played an essential role in the development of the theory of plate tectonics. Moreover, the papers set the stage for emerging future topics in this important interdisciplinary field. With the aggravation of environment pollution and the development of geophysical techniques, the application of environmental geophysical methods is becoming more and more extensive in monitoring and controlling environmental pollution. For this reason, there is drive in the scientific community towards the integration of several geophysical methods in order to detect and characterize the subsoil from the analysis of different physical properties. EEGU introduces nontraditional geophysical conference attendees (regulators, environmental program managers, consultants, and students who are new to near-surface geophysics) to incorporating geophysical approaches into characterization or remediation programs or to evaluating the suitability of geophysical methods for general classes of environmental or engineering problems. In view of the high costs associated with delaying launch and possibly missing launch windows, only a nowcast could provide a sufficiently reliable service. On the environmental level, they have demonstrated that these methods can be used in the zones where drilling of the wells is difficult even impossible or useless in order to delimit the zones where the water resource is exploitable. Geophysical Engineers utilize their extensive knowledge of the earth to identify sites that may contain special mineral or stone deposits that could be of interest to mining companies and other corporations.
