This document provides a record of the discussions conducted by the Geological Observations and Parameterizations (GOP) group, which sought to define and address important questions concerning the parameterization of geological observations for use in stratigraphic simulations. The discussions of this group, which was intermittently composed of a combination of model-building, model-using, and nonmodeling geologists, centered on the type and quality of common geological observations, the scales of these observations, and the accurate representation of observations in geological models. The underlying concerns were whether all relevant processes are accounted for in existing models, and whether modelers are using the available models correctly, inputting realistic values and ranges of values at the proper scales.
Our fundamental questions include the following: How closely is the variability of geological observations reflected in stratigraphic models? If such variability is well represented within a model, how well does a simulation predict away from points of control? If it does not do this well, is it the input parameters that are not reflecting the natural variability of the system, or does the fault lie with the model itself? If the model itself is the limiting factor, how well do we really need to constrain input parameters? How well do we understand the nonlinear characteristics of natural systems, and how are these characteristics introduced into models?

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.
