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!
