On the extraction of channel networks from digital elevation data
TL;DR: A criterion for determining the appropriate drainage density at which to extract networks from digital elevation data is suggested to extract the highest resolution (highest drainage density) network that satisfies scaling laws that have traditionally been found to hold for channel networks.
Journal ArticleDOI
A coupled channel network growth and hillslope evolution model: 1. Theory
TL;DR: In this paper, the authors present a model of the long-term evolution of catchments, the growth of their drainage networks, and the changes in elevations within both the channels and the hillslopes.
Journal ArticleDOI
Hillslope processes, drainage density, and landscape morphology
Gregory E. Tucker,Rafael L. Bras +1 more
TL;DR: In this paper, the consequences of several different hillslope process laws are explored in a series of experiments with a numerical model of drainage basin evolution, including a simple diffusive-advective process transition, a runoff generation threshold, an erosion threshold, and two types of threshold activated landsliding.
