Surrogate‐Model Assisted Plausibility‐Check, Calibration, and Posterior‐Distribution Evaluation of Subsurface‐Flow Models

J Allgeier, OA Cirpka - Water Resources Research, 2023 - Wiley Online Library
Modern physics‐based subsurface‐flow models often require many parameters and
computationally costly simulations. This prohibits traditional ensemble‐based conditioning …

Uncertainty Analysis of Numerical Simulation of Seawater Intrusion Using Deep Learning-Based Surrogate Model

T Miao, H Huang, J Guo, G Li, Y Zhang, N Chen - Water, 2022 - mdpi.com
Seawater intrusion is expected to cause a shortage of freshwater resources in coastal areas
which will hinder regional economic and social development. The consequences of global …

Finite-volume flux reconstruction and semi-analytical particle tracking on triangular prisms for finite-element-type models of variably-saturated flow

P Selzer, J Allgeier, R Therrien, OA Cirpka - Advances in Water Resources, 2021 - Elsevier
Consistent particle tracking relies on conforming velocity fields that ensure local mass
conservation on elements. Cell-centered finite-volume and mixed finite-element methods …

Flux postprocessing and semi-analytical particle tracking for finite-element-type models of variably saturated flow in porous media

P Selzer - 2023 - tobias-lib.ub.uni-tuebingen.de
Aquifers are predominantly conceptualized as porous media. In real-world applications, the
material properties and boundary conditions are heterogeneous requiring numerical models …

Analytical and stochastic numerical methods for the simulation of subsurface flow in floodplains

JT Allgeier - 2023 - tobias-lib.ub.uni-tuebingen.de
Floodplain aquifers are important hydraulic connectors between hillslopes and surface-
water bodies. The flow field in floodplain aquifers comprises different flow components …
