    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...

    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...

    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...
