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 dune sediments and landforms offer a unique opportunity to understand climate change sea level on the centennial-millennial time scale. However, there is paucity of chronological studies effects storms evolution coastal dunes along temperate coastline China. In this study, optically stimulated luminescence (OSL) dating sand was conducted investigate process mechanism southeastern coast ...
“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...
Among the various processes that destroy lands, soil erosion is a complex and hazardous environmental process that constitutes a serious threat to preservation of soil and water resources in Iran and has inflicted its negative effects on the vital ecosystem with the intensified utilization of nature by human beings. The present descriptive and analytic research employed the PSIAC model to study...
Coastal areas constitute one of the most difficult domains to manage, due several human activities and natural processes concentrated in it. The case coastal dunes is special, since they are so fragile any intervention on them can cause alterations landforms dynamics. This work assesses level role management morphological status Catalan Valencian shorelines. To that end, ten beach-dune systems ...
Several coastal barriers experienced significant erosion and change in shape throughout the Mediterranean coasts over past decades, issue has become of increasing concern for scientists policymakers. With reference to a case study by meteorological geomorphological investigations, this note aims define wind–wave conditions, infer net longshore transport, detect processes that landforms Cesine L...
spatial analysis of aeolian landforms by fractal theory (case study: ardestan rig) abstract natural sciences face to a great revolution, nowadays. now, scientists think the world as a collection of complex systems which prediction of consequences of this complex systems is so difficult. in this situation the systems have rotational act so irregularly lead to regular and regularly lead to irregu...
