| Title | Towards an Algebra for Terrain-Based Flow Analysis |
| Creator | Tarboton, David G. Baker, M. E. |
| Description | Topography is an important land surface attribute for hydrology that, in the form of Digital Elevation Models (DEMs), is widely used to derive information for the modeling of hydrologic processes. Much hydrologic terrain analysis is conditioned upon an information model for the topographic representation of downslope flow derived from a DEM, which enriches the information content of digital elevation data. This information model involves procedures for removing spurious sinks, deriving a... |
