| description | This paper uses the elevation-relief ratio to constrain the horizontal and vertical extent of sub-horizontaldenudation surfaces in Wales, United Kingdom. The elevation-relief ratio has been chosen as the appropriategeomorphological parameter as it allows such surfaces to be mapped analytically, even in areas that havebeen subjected to considerable linear denudation; thus, the technique is applicable in a wide range oftopographic settings. For the first time, the elevation-relief ratio has been calculated through the interrogationof the SRTM DEM, using ESRI ArcMap 9.2 GIS software; the methodology has been described in detail.Five sub-horizontal denudation surfaces are recognized at between 40-90 m asl, 118-132 m asl, 173-187m asl, 219-229 m asl, and 385-520 m asl. The number and altitudinal range of these surfaces has not beenrecognized in any previous study; the enduring tripartite division of the Welsh landscape envisaged byBrown (1960) must now be rejected, both in terms of the number of surfaces that may be recognized andtheir altitudinal range. |
