Abstract:

GOLEM is a numerical model that simulates the evolution of topography over geologic time scales. The model was developed by Greg Tucker (then at the Pennsylvania State University Department of Geosciences). The model operates by solving a set of equations that describe the action of various uplift and erosion processes across a grid of cells. The model is designed to simulate landscape evolution on spatial scales ranging from a small watershed to an entire mountain range. For small-scale studies, GOLEM includes equations that describe processes such as weathering, soil creep, landsliding, and channel initiation. For larger-scale studies, GOLEM simulates the evolution of the channel network and parameterizes the action of ``hillslope'' processes within grid cells.

Information on the theory behind GOLEM can be found in Tucker (1996). The theory behind earlier versions of the model is given by Tucker and Slingerland (1994) and by Slingerland and others (1993, Chapter 3). For examples of the model's application to scientific problems, see Tucker and Slingerland (1994, 1996, and 1997), Tucker and Bras (1998), and Gasparini et al. (1999). Related information on theory and applications can be found in the other references listed below.

Although GOLEM has been primarily designed as a research tool, we encourage its use as an educational tool as well. We have found that visualizing the evolution of simulated landscapes is a fascinating and insightful exercise!
