Time-varying sensitivity analysis for mixing in chaotic flows: a comparison study
Carla Feistner, Francesca Ziliotto, Barbara Wohlmuth +1
Engineered injection and extraction systems that create chaotic advection are promising procedures for enhancing mixing between two species. Mixing efficiencies vary considerably,…
Numerical simulation and analysis of mixing enhancement due to chaotic advection using an adaptive approach for approximating the dilution index
Carla Feistner, Mónica Basilio Hazas, Barbara Wohlmuth +1
Lagrangian particle-tracking methods are particularly suitable to study solute transport in velocity fields displaying chaotic advection. They can accurately resolve stretching and…
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…
Bayesian calibration and sensitivity analysis for a karst aquifer model using active subspaces
Mario Teixeira Parente, Daniel Bittner, Steven Mattis +2
In this article, we perform a parameter study for a recently developed karst hydrological model. The study consists of a high-dimensional Bayesian inverse problem and a global sens…
On the relation between parameters and discharge data for a lumped karst aquifer model
Daniel Bittner, Mario Teixeira Parente, Steven Mattis +2
Hydrological models of karst aquifers are often semi-distributed, and physical processes such as infiltration and spring discharge generation are described in a lumped way. Several…
