Urban Geophysics: development of new methods for the interpretation of geophysical data

Abstract

Urban areas are transforming landscapes worldwide. The limited space challenges the study of their subsurface critical for transportation, thermal energy harvesting or environmental impact assessment. In this framework, there is a growing research body developed around Urban Geophysics to provide solutions for understanding the subsurface in complex areas where infrastructures networks and foundations often impair traditional methods both in terms of geophysics and invasive techniques. There is therefore a need to develop those approaches for these specific areas.

The aims of this thesis are the development of modeling methods to account for near-surface networks (cables, pipelines, geomembranes,..) in urban areas for geophysical imaging, the improvement of time-lapse geophysical surveys to monitor remediation actions in urban sites and to improve the characterization of anthropogenic targets. A last task is the multi-modal (boreholes, infrastructures maps, geotechnical maps) data assimilation in the context of urban subsurface mapping.
