We produced a high-resolution model for aquifer heterogeneity in the Terra Cotta Member of the central Kansas Dakota Formation. To improve upon the resolution of modeling techniques currently available, we developed an innovative approach to geometric modeling methods. We used architectural-element analysis to determine the parameters for a stochastic growth model. The growth of the model was accomplished using multiple Monte Carlo simulations, and the result is a detailed model of the architectural elements in the sedimentary basin. The model consists of five layers calibrated to the thickness of the elements determined from interpreted well logs. The horizontal resolution of this model is 50 ft (15.25 m), which is on the order of the horizontal size of the architectural elements. The total horizontal size of the model is 150,000 ft (45,750 m) from east to west by 100,000 ft (30,500 m) from north to south, which covers virtually all of Hodgeman County, Kansas.

Numerical Experiments in Stratigraphy: Recent Advances in Stratigraphic and Sedimentologic Computer Simulations - This volume presents the results derived from a three-day workshop held at the University of Kansas, Lawrence, Kansas, from May 15 through May 17, 1996. The objectives of the workshop were to document, characterize, demonstrate, and compare different computing procedures that have been utilized in simulating stratigraphic sequences. Both inverse and forward simulation modeling procedures are represented. The results of the workshop and the papers assembled here include: (1) an enhanced understanding of similarities and differences between models and modeling philosophies, (2) increased communication among modeling groups and geoscientists, (3) critical evaluation of applications and assessment of how models have been utilized, and (4) improvements and refinements in techniques for generating and describing model input and output.
