An Adaptive Subdivision Algorithm for the Identification of the Diffusion Coefficient in Two-dimensional Elliptic Problems
In this work, we consider the identification problem of the diffusion coef-ficient in two-dimensional elliptic equations. For parameterization, we use the zonation method: the diffusion coefficient is assumed ...

On the Efficiency of the Direct Substitution Approach for Reactive Transport Problems in Porous Media
Nonlinear reactive transport problems can be solved using the Operator Splitting (OS) approach, where transport and reaction processes are separated or the Direct Substitution Approach (DSA) where chemical and...

An Efficient Implementation of the Method of Lines for Multicomponent Reactive Transport Equations
Modeling reactive transport with chemical equilibrium reactions requires solution of coupled partial differential and algebraic equations. In this work, two formulations are developed to combine the method of ...

Accuracy and efficiency of time integration methods for 1D diffusive wave equation
The diffusive wave approximation of the Saint-Venant equations is commonly used in hydrological models to describe surface flow processes. Numerous numerical approaches can be used to solve this highly nonline...

Hydrological and vegetation response to climate change in a forested mountainous catchment
Vegetal cover and the water cycle are closely linked. The climate controls the distribution and productivity of terrestrial vegetation, and the vegetal cover type is a key determinant for evapotranspiration an...

A low-dimensional subsurface model for saturated and unsaturated flow processes: ability to address heterogeneity
A low-dimensional model that describes both saturated and unsaturated flow processes in a single equation is presented. Subsurface flow processes in the groundwater, the vadose zone, and the capillary fringe a...

Grid convergence for numerical solutions of stochastic moment equations of groundwater flow
We provide qualitative and quantitative assessment of the results of a grid convergence study in terms of (a) the rate/order of convergence and (b) the grid convergence index, GCI, associated with the numerica...

Open AccessEstimating the activation energy of bond hydrolysis by time-resolved weighing of dissolving crystals
Bond-breaking activation energy EB is nowadays a key parameter for understanding and modeling crystal dissolution processes. However, a methodology to estimate EB based on classical dissolution experiments still ...
