A Comparison Of Three Terrain Parameters That May Be Used To Identify Denudation Surfaces Within A Gis: A Case Study From Wales, United Kingdom., Matt D. Rowberry
Matt D Rowberry
The study of denudation surfaces has long formed a major theme within geomorphic and tectonic research. This paper describes the computational methods used to identify these surfaces through three terrain parameters within a GIS. The investigated parameters are slope angle, relative relief, and the elevation-relief ratio. The study area under consideration is that of Wales, United Kingdom. The SRTM DEM forms the basis of this investigation, with all data interrogation undertaken in ArcMap 9.3. The computational methods are described in detail and then the results relating to each terrain parameter are compared. The denudation surface maps based on slope angle …
