This paper will review a mathematical model that simulates the physical runoff and erosion processes that are believed to occur on hillslopes and channels of a typical catchment. More importantly, the model is able to explicitly model the growth

The A. develops a three-dimensional numerical model of fluvial landsculpting operative over large periods of time and large spatial scales. The model is based on simple approximations intended to capture the synoptic effects of fluvial processes
. Experiments with the model also offer tentative insight into how climatic and tectonic variables affect the evolqution of landscapes. The results of the model also relate to the complexity of natural landscape and its description through the language

The temporal discontinuity in geomorphic processes that is responsible for time-scale dependence in published process rates (Gardner et al., 1987) is effectively modeled by a fractal construction, the Cantor dust. Fractal dimension values estimated
for processes of uplift (0.75) and denudation (0.81) suggest that uplift events are only slightly more clustered in time than are denudation events. The results obtained from application of this model are unaffected by variability in magnitude of events.
