Many geophysical inverse problems are ill-posed and their solution non-unique. It is thus important to reduce the amount of mathematical solutions to more geologically plausible models by regularizing the inverse problem and incorporating all available prior information in the inversion process. We compare three different ways to incorporate prior information for electrical resistivity tomography (ERT): using a simple reference model, adding structural constraints to Occam’s inversion and using… 

Covariance-constrained difference inversion of time-lapse electrical resistivity tomography data

ABSTRACTHydrogeophysics has become a major field of research in the past two decades, and time-lapse electrical resistivity tomography (ERT) is one of the most popular techniques to monitor passive

Constrained electrical resistivity tomography Bayesian inversion using inverse Matérn covariance matrix

Bayesian inversion using maximum a posteriori estimator is a quantitative approach that has been successfully applied to the electrical resistivity tomography inverse problem. In most approaches,

Electrical resistivity tomography has become a standard geophysical method in the field of hydrogeology, as it has the potential to provide important information regarding the spatial distribution

Enhancing the information content of geophysical data for nuclear site characterisation

This thesis examines various aspects of uncertainty in ERT and develops new methods to better use geophysical data quantitatively and proposes that the various steps in the general workflow of an ERT study can be viewed as a pipeline for information and uncertainty propagation and suggested some areas have been understudied.

Uncertainty in training image‐based inversion of hydraulic head data constrained to ERT data: Workflow and case study

A workflow inspired by a Popper‐Bayes philosophy that data should first be used to falsify models, then only be considered for matching, is proposed, highlighting the importance of considering and estimating prior uncertainty (without data) through a process of probabilistic falsification.

CONSTRAINING ELECTRIC RESISTIVITY TOMOGRAPHY BY DIRECT PUSH ELECTRIC CONDUCTIVITY LOGS AND VIBRACORES: AN EXEMPLARY STUDY OF THE FIUME MORTO SILTED RIVERBED (OSTIA ANTICA, WESTERN ITALY)

The inversion of geoelectric data is non-unique. Therefore, electric resistivity tomography (ERT) usually results in different subsurface models that fit observed apparent resistivity values equally
