Abstract Global terrain classification data have been used for various issues related to topography such as the estimation of soil types and ground vulnerability earthquakes creation seismic hazard maps. However, due resolution digital elevation models (DEMs), from previous studies could not discriminate small landforms plains at bottom narrow valleys rises in plains. Owing greater regional var...
The Jacotines landslide is representative of the large mass movements that affect Champagne vineyards. Understanding subsurface structure these slopes and mechanisms leading to sliding events a great interest, particularly for winegrowers who produce Champagne. This knowledge generally used elaborate accurate hazard assessment maps, which an important feature in land use planning. approach pres...
Abstract Sub-Antarctic Marion Island's glacial history has acted as a control on abiotic terrestrial processes and the colonization distribution of biotic species found island today. Recent chronological studies have shown an early deglaciation identified new geomorphological features associated with past ice dynamics. These permit reassessment extent during after island's last local maximum. I...
Liechtenstein has faced an increasing number of natural hazards over recent decades: debris flows, slides, snow avalanches and floods repeatedly endanger the local infrastructure. Geomorphological field mapping and geoelectrical profiling was used to assess hazards near Malbun, a village potentially endangered by landslides, and especially debris flows. The area is located on the tectonic conta...
in recent years, the occurrence of water and wind erosion indifferent parts of country due to the changes of land use from the forest andpasture into the agricultural and also construction of communication lineshave increased. the study and research on this phenomenon, the effectivefactors in creating them and also identification of geomorphology faciestypes are necessary to prevent the waste o...
A generic procedure for semantics-oriented landform classification using object-based image analysis
In most landform classification studies – either per cell or object-based – the authors have ignored modeling the semantics of landforms explicitly. Thus, landform classification schemes rely on individual knowledge, and are too much tailored to specific areas and/or scales. Integration of structured knowledge models in the classification process has been proposed to overcome the limitations in...
Marine-based ice streams whose beds deepen inland are thought to be inherently unstable1–3. This instability is of particular concern because significant portions of the marinebased West Antarctic and Greenland ice sheets are losing mass and their retreat could contribute significantly to future sea-level rise4–7. However, the present understanding of icestream stability is limited by observati...
Landslide inventories provide the knowledge basis for many geomorphological applications and also planning emergency management. Detailed landslide should be prepared where pre-existing are available, as updates. In this paper, we present a new inventory an area of High Agri Valley, Southern Italian Apennines. The map was through systematic interpretation historical aerial photographs testing e...
Introduction: The recent observations about different waterand ice-related features on Nepenthes region of Mars [1] [2] [3], and the evidence of changes on the Oceanus Borealis’ water level on this region [4] [5] inspired the work here presented. What are exactly the water-related landforms (glacial, periglacial, fluvial, etc) existing in this region of Mars? How are they spatially distributed?...
