geomorphologic landforms associated with tourism and development has been considered by many researchers in recent years. geomorphologic landforms which have values and capabilities, considered in context of tourism, known as geomorphosite and are studied in geomorphotourism approach. in this paper, we used landsat satellite imageries, geological and topographic maps, data obtained by field obs...

RESUME This work concerns the application of SAR interferometry for the assessment of the long-term analysis of the state of activity of deep seated mass movements affecting some urban areas in the northern Appennines of Emilia Romagna region (from 1994-2001 space-borne ERS data) and for the real-time monitoring of active flow-like landslides in year 2002 (from ground-based system). These activ...

[1] The reason for the survival of mountainous topography in ancient orogenic belts is a long-standing problem in geomorphology and geodynamics. We explore the geomorphologic controls on the timescale for the postorogenic decay of topography to address the question of whether there is a viable geomorphologic explanation for the persistence of topography in ancient orogenic belts or whether alte...

[1] Understanding the processes controlling chemical sedimentation is an important step in deciphering paleoclimatic conditions from the rock records preserved on both Earth and Mars. Clear evidence for subaqueous sedimentation at Meridiani Planum, widespread saline mineral deposits in the Valles Marineris region, and the possible role of saline waters in forming recent geomorphologic features ...

Stream networks are important features for hydrologic modeling, geomorphologic analysis of landscape, and many other applications. Automatic extraction of stream network from digital elevation model (DEM) has been implemented in major GIS software such as ArcGIS and GRASS based on flow direction along steepest descent and using some threshold criteria to separate channels and hillslope. However...
