Impacts of peak-flow events on hyporheic denitrification potential
Tanu Singh, Shubhangi Gupta, Gabriele Chiogna +2
Subsurface flows, particularly hyporheic exchange fluxes, driven by streambed topography, permeability, channel gradient and dynamic flow conditions provide prominent ecological se…
Alpine Permafrost Modeling: On the influence of topography driven lateral fluxes
Jonas Beddrich, Shubhangi Gupta, Barbara Wohlmuth +1
Alpine permafrost environments are highly vulnerable and sensitive to changes in regional and global climate trends. Thawing and degradation of permafrost has numerous adverse envi…
An all-at-once Newton strategy for methane hydrate reservoir models
Shubhangi Gupta, Barbara Wohlmuth, Matthias Haeckel
Marine gas hydrate systems are characterized by highly dynamic transport-reaction processes in an essentially water-saturated porous medium that are coupled to thermodynamic phase…
Efficient parameter estimation for a methane hydrate model with active subspaces
Mario Teixeira Parente, Steven Mattis, Shubhangi Gupta +2
Methane gas hydrates have increasingly become a topic of interest because of their potential as a future energy resource. There are significant economical and environmental risks a…
Testing a coupled hydro-thermo-chemo-geomechanical model for gas hydrate bearing sediments using triaxial compression lab experiments
Shubhangi Gupta, Christian Deusner, Matthias Haeckel +2
Natural gas hydrates are considered a potential resource for gas production on industrial scales. Gas hydrates contribute to the strength and stiffness of the hydrate-bearing sedim…
Multi-rate time stepping schemes for hydro-geomechanical model for subsurface methane hydrate reservoirs
Shubhangi Gupta, Barbara I. Wohlmuth, Rainer Helmig
We present an extrapolation-based semi-implicit multirate time stepping (MRT) scheme and a compound-fast MRT scheme for a naturally partitioned, multi-time-scale hydro-geomechanica…
Non-Isothermal, Multi-phase, Multi-component Flows through Deformable Methane Hydrate Reservoirs
Shubhangi Gupta, Rainer Helmig, Barbara Wohlmuth
We present a hydro-geomechanical model for subsurface methane hydrate systems. Our model considers kinetic hydrate phase change and non-isothermal, multi-phase, multi-component flo…
