Python package for generating periodic hydraulic conductivity fields and groundwater flow fields



This is a Python package, periodicgw (available at, for generating 2D periodic random groundwater flux fields with any user specified mean flow vector. Periodic random hydraulic conductivity fields are generated that are locally multi-Gaussian with user-selectable semi-variograms and anisotropy structures. Darcy flux fields are solved exactly using a finite volume approach on these conductivity fields with periodic boundary conditions and an enforced mean flow angle. Inter-cell fluxes are directly reported for compatibility with particle tracking algorithms based on the Pollock method. Source code of this Python package is attached.
