The concavity, or curvature, of river profiles has long been taken to be a fundamental indicator of the underlying processes governing fluvial erosion, and thereby of landscape evolution. However, erosion laws have generally been derived without accounting for the strong orographically driven gradients in precipitation typically found in mountainous regions. In addition, field measurements have...

Land use and cover (LUC) of southern European mountains is dramatically changing, mainly due to observed socioeconomic demands climatic changes. It therefore important understand LUC changes accurately predict future landscapes their threats. Simulation models change are ideal for this task because they allow the in silico experimentation under different scenarios. In present study, we employed...

Consumer-grade digital imagery captured by nonexperts has a great potential for DEM extraction. The portability of the equipment creates opportunities for data collection in difficult and inaccessible mountainous terrain. In this context it provides an important tool enabling rapid response post-disaster planning in regions affected by large scale natural hazard events. The potential of this me...

The knowledge of the surface topography has a major importance in the field of Earth sciences. It is essential in any discipline concerned with process modeling like hydrology, climatology, geomorphology and ecology. The present study utilized Environmental Systems Research Institute’s (ESRI) ArcGIS 9.3 (with the spatial analyst extension) software, remote sensing data ( DEM and Digital Aerial ...

Land abandonment in European mountains threatens habitats shaped for centuries by low-intensity agriculture and grazing. Hence, it is important to identify spatiotemporal patterns rural abandonment, relate them biophysical socioeconomic drivers. We pursued these goals the theoretical context of transitions from traditional productivist then post-productivist agriculture. conducted a case study ...

iran has mountainous landscapes and half of its surface is occupied by highlands. moreover, iran is an arid country and deserts are located at lower altitudes. most metropolitan areas are positioned in mid-altitudes between mountain and desert. cities grow upwardly toward the highlands under pressures of urbanization and desertification. foothill ecotones are a zone between upland mountains and...
