Advances in the mapping of flow networks from digital elevation data

D. Tarboton, D. Ames
Geography
15 May 2001

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 the flow… Expand
