A new procedure for the representation of flow directions and calculation of upslope areas
using rectangular grid digital elevation models is presented. The procedure is based on …

Channel networks with artibtrary drainage density or resolution can be extracted from digital
elevation data. However, for digital elevation data derived networks to be useful they have …

Ever since Mandelbrot (1975, 1983) coined the term, there has been speculation that river
networks are fractals. Here we report analyses done on river networks to determine their …

The analysis of large river networks obtained from digital elevation models has given insight
into the variation of channel slope with scale. Investigators have recently suggested that …

Drainage density, a basic length scale in the landscape, is recognized to be the transition
point between scales where unstable channel-forming processes yield to stable diffusive …

Digital elevation models (DEMs) are a useful data source for the automatic delineation of flow
paths, sub watersheds and flow networks for hydrologic modeling. Digital representation of …

This module is designed to provide a comprehensive and quantitative understanding of
infiltration and runoff generation processes. The module should take in 6-15 hours to complete …

The structure and scaling of river networks characterized using fractal dimensions related to
Horton's laws is assessed. The Hortonian scaling framework is shown to be limited in that …

This paper describes an energy balance snowmelt model developed for the prediction of rapid
snowmelt rates responsible for soil erosion and water input to a distributed water balance …

This work examines patterns of regularity and scale in landform and channel networks. Digital
elevation model data sets from throughout the United States are used as a data source. …
