Three-Dimensional Steady-state Groundwater Flow Modeling with Full Tensor Conductivities Using Finite Difference

A new three-dimensional steady-state groundwater-flow forward-simulator with full conductivity tensors using a nineteen-points block-centered finite-difference method is presented. Hydraulic conductivity tensors are defined at the block interfaces eliminating the need to average conductivity tensors...
