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…

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…
