The Gangotri Glacier, at the source of the Ganges River, has fluctuated greatly throughout the late Quaternary in response to climatic oscillations. This has resulted in impressive moraines, paraglacial debris flow fans and terraces along the upper stretches of the Bhagirathi Valley. Cosmogenic radionuclide (CRN) dating of glacial and paraglacial landforms shows that fans, terraces and associat...

As the largest service industry in the world, tourism plays a special role in sustainable development. Geomorphic tourism is known to be a segment of this industry with lower environmental impact and underlying causes that explain lower demand; therefore, it is essential to study, identify, assess, plan, and manage natural tourist attractions. As such, the present study assesses the ability of ...

Coastal areas are exposed to high levels of human occupation, which has led their degradation. dunes have been greatly altered by different historical and current land uses, causing the loss natural cultural values. On coast Tenerife there volcanic organogenic sand active relict with multiple most prominent is tourism (also main cause deterioration). The aim this study demonstrate relevance geo...

During the lowstand sea-level phase of Last Glacial Maximum (LGM), a large part current Mediterranean continental shelf emerged. Erosional and depositional processes shaped coastal strips, while inland areas were affected by aeolian fluvial processes. Evidence both subsequent phases eustatic sea level rise can be observed on Sardinia (Italy), including submerged palaeo-shorelines landforms, ind...

Aeolian ripples arise instantaneously from sandy beds subjected to winds sufficient to cause saltation to surface grains. It is now widely believed that the process of ripple formation is a self-organizing phenomenon involving non-linear dynamics in the variation of flux of secondary grains that are ejected through saltation. In addition, the metric entropy and interaction matrix of the system ...

“Danxia landform” is a landform type originally defined in China, characterized by red-colored sandstones and steep cliffs, and developed through long-term erosion. In recent years, Danxia landforms have been receiving international attention, and six examples in China became a UNESCO World Natural Heritage in 2010. However, morphometric studies of Danxia landforms in China have been very limit...

Climbing dunes are typical aeolian landforms. The study of their formation and development mechanisms is necessary for the prevention control dune migration. gradient shape important geomorphic factors affecting climbing dunes, but influencing mechanism not clear at present. In this work, wind speed sand deposition on a sloping surface were monitored constant 8 m s−1 in wind-tunnel experiments,...

Aeolian process leads to the transportation and accumulation of sand particles that result in dune landforms. The structure shape dunes are driven by parameters interacting wind force material composition within. Cross-section profiles over will essay geomorphological through which steady state rate transport can be computed. National Aeronautics Space Administration’s novel satellite namely Ic...

Abstract The wide spatial coverage of sand dunes in continental interiors makes the understanding their activity and accumulation history valuable for palaeoenvironmental reconstructions interpretation landscape evolution. Nevertheless, study aeolian development at million‐year timescale is hampered by complex interaction factors determining dune migration inherently self‐destructive nature chr...

[1] This paper describes selection and characterization of the landing site for the Mars 2004 Beagle 2 mission. The site is within Isidis Planitia between 10 –12 N, 266 – 274 W, centered at 11.6 N, 269.5 W. This is at low elevation ( 3600 to 3900 m MOLA), is flat (MOLA RMS slope = 0.57 ), radar data suggest a smoother surface at decimeter to meter scales than the Pathfinder site and it has a mo...
