Scale factor and digital elevation analysis for hydrological studies [PDF]

open access: yes, 2007
The digital elevation model (DEM) is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. The DEM is a model of the elevation surface, which is subject to errors.

Digital Elevation Models (Experimental Bed)

open access: yes, 2018
Digital Elevation Models from Bed Scans used in the following paper: Elgueta-Astaburuaga and Hassan, Sediment storage, partial transport, and the evolution of an experimental gravel bed under changing sediment supply regimes, submitted to Geomorphology in 2018. Each DEM name specifies the run R(1-7) in which it was collected and time H(1-40).

Unit 38 - Digital Elevation Models

open access: yes, 1990
This unit considers digital elevation models (DEMs) as one way of representing surfaces. It describes how DEMs are created and used, particularly in hydrology. Approaches for estimating elevation, slope and aspect, and for determining drainage networks are presented, along with a discussion of issues that may arise when automatically determining ...
