Uncertainty Quantification of the Fresh-Saltwater Interface from Time-Domain Electromagnetic Data
Arsalan Ahmed, Thomas Hermans, David Dudal +1
Geophysical methods provide a cost-effective way to characterize the subsurface for hydrogeological projects, but they rely on solving an inverse problem. Traditionally, determinis…
Quantitative imaging of the fresh/saltwater interface with airborne electromagnetics: examining different sources of uncertainty
Wouter Deleersnyder, David Dudal, Thomas Hermans
Knowing the distribution between fresh and saline groundwater is imperative for sustainable and integrated management of water resources in coastal areas. The airborne electromagne…
A multidimensional AI-trained correction to the 1D approximate model for Airborne TDEM sensing
Wouter Deleersnyder, David Dudal, Thomas Hermans
The computational resources required to solve the full 3D inversion of time-domain electromagnetic data are immense. To overcome the time-consuming 3D simulations, we construct a s…
Determining the optimal focusing parameter in sparse promoting inversions of EMI surveys
Wouter Deleersnyder, David Dudal, Benjamin Maveau +1
If the magnetic field caused by a magnetic dipole is measured, the electrical conductivity of the subsurface can be determined by solving the inverse problem. For this problem, a f…
Novel Airborne EM Image Appraisal Tool for Imperfect Forward Modelling
Wouter Deleersnyder, David Dudal, Thomas Hermans
Full 3D inversion of time-domain Airborne ElectroMagnetic (AEM) data requires specialists' expertise and a tremendous amount of computational resources, not readily available to ev…
Flexible quasi-2D inversion of time-domain AEM data, using a wavelet-based complexity measure
Wouter Deleersnyder, Benjamin Maveau, David Dudal +1
Regularization methods improve the stability of ill-posed inverse problems by introducing some a priori characteristics for the solution such as smoothness or sharpness. In this co…
Inversion of electromagnetic induction data using a novel wavelet-based and scale-dependent regularization term
Wouter Deleersnyder, Benjamin Maveau, Thomas Hermans +1
The inversion of electromagnetic induction data to a conductivity profile is an ill-posed problem. Regularization improves the stability of the inversion and, based on Occam's razo…
