Diffusion models for multivariate subsurface generation and efficient probabilistic inversion
Roberto Miele, Niklas Linde
Diffusion models offer stable training and state-of-the-art performance for deep generative modeling tasks. Here, we consider their use in the context of multivariate subsurface mo…
Two-dimensional probabilistic inversion of plane-wave electromagnetic data: Methodology, model constraints and joint inversion with electrical resistivity data
M. Rosas-Carbajal, N. Linde, T. Kalscheuer +1
Probabilistic inversion methods based on Markov chain Monte Carlo (MCMC) simulation are well suited to quantify parameter and model uncertainty of nonlinear inverse problems. Yet,…
Focused time-lapse inversion of radio and audio magnetotelluric data
M. Rosas Carbajal, N. Linde, T. Kalscheuer
Geoelectrical techniques are widely used to monitor groundwater processes, while surprisingly few studies have considered audio (AMT) and radio (RMT) magnetotellurics for such purp…
Conditioning of stochastic 3-D fracture networks to hydrological and geophysical data
C. Dorn, N. Linde, T. Le Borgne +2
The geometry and connectivity of fractures exert a strong influence on the flow and transport properties of fracture networks. We present a novel approach to stochastically generat…
3D density structure and geological evolution of Stromboli volcano (Aeolian Islands, Italy) inferred from land-based and marine gravity data
N. Linde, L. Baron, T. Ricci +5
We present the first density model of Stromboli volcano (Aeolian Islands, Italy) obtained by simultaneously inverting land-based (543) and sea-surface (327) relative gravity data.…
Joint inversion in hydrogeophysics and near-surface geophysics
N. Linde, J. Doetsch
The near-surface environment is often too complex to enable inference of hydrological and environmental variables using one geophysical data type alone. Joint inversion and coupled…
Tomogram-based comparison of geostatistical models: Application to the MAcro-Dispersion Experiment (MADE) site
N. Linde, T. Lochbühler, M. Dogan +1
We propose a new framework to compare alternative geostatistical descriptions of a given site. Multiple realizations of each of the considered geostatistical models and their corre…
Geological realism in hydrogeological and geophysical inverse modeling: a review
N. Linde, P. Renard, T. Mukerji +1
Scientific curiosity, exploration of georesources and environmental concerns are pushing the geoscientific research community toward subsurface investigations of ever-increasing co…
Image synthesis with graph cuts: a fast model proposal mechanism in probabilistic inversion
T. Zahner, T. Lochbühler, G. Mariethoz +1
Geophysical inversion should ideally produce geologically realistic subsurface models that explain the available data. Multiple-point statistics is a geostatistical approach to con…
Summary statistics from training images as prior information in probabilistic inversion
T. Lochbühler, J. A. Vrugt, M. Sadegh +1
A strategy is presented to incorporate prior information from conceptual geological models in probabilistic inversion of geophysical data. The conceptual geological models are repr…
Structure-coupled joint inversion of geophysical and hydrological data
T. Lochbühler, J. Doetsch, R. Brauchler +1
In groundwater hydrology, geophysical imaging holds considerable promise for improving parameter estimation, due to the generally high resolution and spatial coverage of geophysica…
Effective modeling of ground penetrating radar in fractured media using analytic solutions for propagation, thin-bed interaction and dipolar scattering
A. Shakas, N. Linde
We propose a new approach to model ground penetrating radar signals that propagate through a homogeneous and isotropic medium, and are scattered at thin planar fractures of arbitra…
Fracture imaging within a granitic rock aquifer using multiple-offset single-hole and cross-hole GPR reflection data
C. Dorn, N. Linde, J. Doetsch +2
The sparsely spaced highly permeable fractures of the granitic rock aquifer at Stang-er-Brune (Brittany, France) form a well-connected fracture network of high permeability but unk…
