MODFLOW-2000 model used to illustrate the differences in flow paths and travel times when
three-dimensional kriging is used to estimate the hydraulic conductivity distribution as compared to manual
determinations of hydraulic conductivity distribution
A three-dimensional (3D) groundwater flow model of the glaciated sediments around Elkhart, Indiana 
was constructed as part of the U.S. Geological Survey Groundwater Resources Program using 
lithologic records from water well logs. Texture-based hydraulic conductivities were assigned to 
vertical intervals along each …
