On the extraction of channel networks from digital elevation data
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. Expand
Hillslope processes, drainage density, and landscape morphology
Catchment morphology and drainage density are strongly influenced by hillslope processes. The consequences of several different hillslope process laws are explored in a series of experiments with aExpand
A coupled channel network growth and hillslope evolution model: 1. Theory
This paper presents 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. ElevationExpand
The Channel-Hillslope Integrated Landscape Development Model (CHILD)
By providing the much-needed connection between measurable processes and the dynamics of long-term landscape evolution that these processes drive, mathematical landscape models have posed challenging new hypotheses and have provided the guiding impetus behind new quantitative field studies and Digital Elevation Model -based analyses of terrain.

Precipitation recycling in the Amazon basin
SUMMARY Precipitation recycling is the contribution of evaporation within a region to precipitation in that same region. The recycling rate is a diagnostic measure of the potential for interactionsExpand
Energy dissipation, runoff production, and the three-dimensional structure of river basins
Three principles of optimal energy expenditure are used to derive the most important structural characteristics observed in drainage networks: (1) the principle of minimum energy expenditure in anyExpand
A stochastic approach to modeling the role of rainfall variability in drainage basin evolution
We develop a simple stochastic theory for erosion and sediment transport, based on the Poisson pulse rainfall model, in order to analyze how variability in rainfall and runoff influences drainageExpand
Preserving high-resolution surface and rainfall data in operational-scale basin hydrology: a fully-distributed physically-based approach
Abstract This study presents various aspects of the continuous simulation capabilities of a fully-distributed, triangulated irregular network (TIN) hydrologic model. The TIN-based Real-timeExpand
