AB  - The semi-arid terrain of South-eastern Spain is vulnerable to geohazards,including flash-flood erosion, landslides and seismic risk. Developing urbanisation,quarrying and mining, road building and changing agricultural practices are affectedby geohazards and in some cases create them. For example, instability on new roadcuts and embankments, and ploughing of natural, regolith-soil surfaces renderspreviously stable terrain vulnerable to ‘badland’ gully erosion, soil loss and causesincreased reservoir siltation.This paper reports the results of a comparative study of the uses of LandsatTM, and SPOT Pan, in conjunction with a Digital Elevation Model (DEM) forgeohazard identification and mapping. We have also investigated aspects of geohazardscaused by changes in land use and infra-structure development since LandsatTM imagery became available in 1984.Study targets include: terrain at risk from mass movement ‘badland’ terrain in unconsolidated sediments disturbance of land surfaces by agricultural development. Expansion of communications infrastructure and quarrying in relation to naturalhazards.The methodology for integrated hazard mapping involves directed enhancement,merging and draping of multi-spectral, and panchromatic imagery with the DEM tocreate three dimensional image products for mapping. The paper concludes withrecommendations for combined image and DEM usage in geohazard assessment.
