Original publication date November 25, 1995.
To develop a high-resolution model for aquifer heterogeneity in the
Terra Cotta Clay Member of the central Kansas Dakota Formation, a
detailed study of the architectural elements prevailing in the outcrop
region of the aquifer was conducted. On the basis of the information
collected during this field study, a stochastic model was developed to
characterize lithic heterogeneity within the sedimentary basin.
To simulate the stratigraphy of the Dakota aquifer in central Kansas,
twenty-nine outcrops of the Dakota Sandstone in central Kansas were
studied, and the data was put into the stochastic growth model, which
produced a set of likely basin configurations. This preliminary report
presents our results, and previews the work that will be accomplished
during the second year of the project.
