Probabilistic delineation of subsurface connected pathways in alluvial aquifers under geological uncertainty

M Schiavo - Journal of Hydrology, 2022 - Elsevier
The present work aims to address the issue of the delineation of subsurface pathways
carved in sedimentary aquifers from a stochastic perspective. A probabilistic approach to …

Pathline density distributions in a null‐space Monte Carlo approach to assess groundwater pathways

C Moeck, J Molson, M Schirmer - Groundwater, 2020 - Wiley Online Library
A null‐space Monte‐Carlo (NSMC) approach was applied to account for uncertainty in the
calibration of the hydraulic conductivity (K) field for a three‐dimensional groundwater flow …

Hydrogeological uncertainty estimation with the analytic element method

M Ramgraber, M Schirmer - Water Resources Research, 2021 - Wiley Online Library
Uncertainty estimation plays an important part in practical hydrogeology. With most of the
subsurface unobservable, attempts at system characterization will invariably be incomplete …

[PDF][PDF] Boundary and Initial Condition Issues for Computational Fluid Dynamics (CFD) and Modeling and Simulation (Mod-Sim)

DM Bushnell - 2021 - ntrs.nasa.gov
For many important classes of Mod-Sim problems, even quantum computing will not enable
accurate predictions/computation vis-à-vis the real world due to boundary/initial condition …
