Description :
The Gödöllő Hills, a low-relief terrain within the Central Pannonian Basin in Hungary, is characterised by moderate tectonic deformation rates. Although typical tectonic landforms are not clearly recognisable in the study area, this paper succeeded in discriminating between tectonically controlled landforms and features shaped by fluvial erosion or deflation with no tectonic control. DEM-based morphometric parameters including elevation, slope and surface roughness, enabled the delineation of two NW-SE trending spearhead-shaped ridges separated by a wide rectilinear valley of the same strike. Deflation plays a significant role in shaping the area, and the presence of two large-scale yardangs separated by a wind channel is proposed. Characteristics drainage patterns and longitudinal valley profiles enabled the recognition of areas probably affected by neotectonic deformation.
