Texture-based hydraulic conductivities were assigned to \nvertical intervals along each lithology record. A three-dimensional kriging program read texture-based \nhydraulic conductivity values for each vertical interval and calculated a continuous 3D distribution of \nhydraulic conductivity for the entire model domain. The model was calibrated to hydrologic conditions \nin May and June of 1979. The model was used to simulate groundwater flow paths from points of \nrecharge to points of discharge. These flow paths were compared to flow paths generated by an \nexisting model (https://pubs.usgs.gov/wri/1997/4204/report.pdf) that was constructed using a manual \napproach to create the hydraulic conductivity distribution and calibrated to the same hydrologic \nconditions. The model using the kriged hydraulic conductivity distribution had 30 vertically discretized \nlayers, and the model using the the manually created hydraulic conductivity distribution had two \nvertically discretized layers.
