A erosão dos solos é um problema frequentemente relatado em todo o globo, qual compromete a utilização do recurso pedológico, essencial para reprodução da atividade humana. Para as áreas declivosas, como caso das Cuestas Basálticas Estado de São Paulo, este pode se tornar ainda maior partir características naturais terreno, que podem funcionar catalizadoras processos erosivos. disto, objetivo d...

While there is abundant geomorphologic evidence for landslides in Iceland, it is in most cases unknown whether or not these landslides are actively creeping. Here we use Interferometric Synthetic Aperture Radar (InSAR) to assess its monitoring capabilities on three landslides that are known to be creeping and to survey large areas in East and Central-North Iceland in search for other creeping l...

Geoinformation is an important basis for planning strategies, natural hazard modelling, process detection, and risk analysis. Airborne Laser Scanning is an operational working method for area wide data acquisition and provides 3D information in a high spatial resolution. The data contains detailed information to characterise surface properties which is, however, not obvious to extract from the ...

The present study deals with the inter-relations in the relief which forms the Bacia do Alto Rio Paraguay (BAP) in mid-west Brazil. The overall aim is to discuss the relationship between relief forms and the biodiversity of the Pantanal. The BAP is a natural environmental system with contrasts in two of the compartments on which it is formed: the plateau, the most elevated compartment, highly t...

Digital elevation models (DEMs) are increasingly used for visual and mathematical analysis of topography, landscapes and landforms, as well as modeling of surface processes. A DEM of Cerro Sillajhuay, a volcano in the Andes of Chile/Bolivia, was developed from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) satellite data. The original 30-m DEM was generated by using tie ...

Two loud explosions accompanied by two successive big dark clouds that would have been 300 metres high, had taken place at El Humazo geothermal manifestation at February 2003. These explosions produced some important geomorphologic and structural changes that were registered in the geothermal area and its surroundings. Among these, it can be mentioned the reactivation of a geothermal manifestat...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...
