Applicability and Interpretation of Geophysical Results in Relation to Engineering and Environmental Properties

 

The purpose of this PhD project is to evaluate the possibility to use the resistivity-induced polarisation (DCIP) imaging method for predicting engineering and environmental key parameters in connection with infrastructural developments in urban environments. Commercial 3D algorithms for DCIP inversion completely disregard the spectral content contained in the IP decays. This implies a significant loss of information in the inversion process. More sophisticated inversion approaches will be developed in the project and the output evaluated in this subproject. The lack of understanding that exists in the correlations between IP and the engineering/environmental parameters, especially about the IP spectral characteristics, will be in focus. Thus the possibility to establish more accurate characterisation of engineering and environmental key properties based on models derived from inversion of spectral time-domain IP data will be investigated. This includes soil and rock properties, tectonic structures, existence and character of buried waste and derelict industrial areas, as well as water and contaminant occurrence and transport.

Geoelectrical Imaging Techniques in Urban Environments

 

The purpose of this PhD project is to develop and adapt the resistivity-induced polarisation (DCIP) imaging method for use in infrastructural developments in urban environments. The urban environment is intrinsically three dimensional and presents logistic limitations that often prevent regular geometries of the electrode spreads. Furthermore, several sources of noise are present. These specificities require adapted electrode configurations and advanced signal processing schemes. The need of using 3D models in turn demands much greater amounts of data. More scalable and faster acquisition systems are required for a cost effective applicability of DCIP.
