Tribe (1992) provided a review of a number of methods for the automated delineation of
valley lines and drainage networks from grid digital elevation models (DEM). Two …

The literature on valley and drainage line recognition from grid digital elevation models
(DEMs) is reviewed. Two problems preventing the successful delineation of fully connected …

An approach to the automatic derivation of drainage networks from digital elevation models
(DEMs) using regular-gridded data is described. Features such as depressions and …

One problem in drainage networks studies is the amount of effort which is needed to identify
the drainage net and to measure basic properties. First, the drainage network must be …

Drainage direction assignment over flat surfaces in raster Digital Elevation Models (DEM)
has been a stubborn problem for DEM processing methods. A new approach that improves …

A major problem in developing digital elevation models (DEMs) is the realistic
representation of flow though complex terrain. A contour‐based DEM, which uses natural …

A set of ten algorithms to automate the determination of drainage network and subcatchment
areas from Digital Elevation Models (DEMs) is presented. The algorithms perform such tasks …

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 …

Based on existing principles of automated drainage network extraction we have developed
two methodological algorithms, the “profile scan” and “hydrological flow modeling,” and …

Current algorithms that deduce the drainage network from a digital elevation model (DEM)
represented by a regular array of surface elevations share a fault: Unless the terrain is …
