Abstract
Groundwater is one of the most important water resource for many country, and adequate management is required to use it sustainably. Modeling and simulation are the strong tool for groundwater management. However, hydraulic conductivity distribution of the flow field has been ig.nored in the most of simulations. In this report, the outline of the model for spatial distribution of hydraulic conductivity is described, and some examples of the numerical simulations in the non-uniform flow field are introduced.
