In an age of both big data and increasing strain on water resources, sound management decisions often rely on numerical models. Numerical models provide a physics-based framework for assimilating and ...

"In this course we will be utilizing MODFLOW, the USGS's modular hydrologic model, for illustrating and solving contaminant transport processes and problems. To ...

Model spatial discretization, referred to herein as a model grid, serves as the foundation for building hydrologic models in GSFLOW. GSFLOW and MODFLOW-NWT model grids are structured cellular grids, ...

Electrostatic coupling occurs while simulating the transport of ionic (charged) chemical species. The condition of electroneutrality leads to a coupled nonlinear solute transport equation, where the ...
