knowledge about spatial soil variation in terms of measured pedodiversity offers the possibility to estimate the quality and variance within a soil map. diversity indices and abundance distribution models are statistical tools which ecologists have applied for decades for analyzing the intrinsic regularities of various ecological entities. in this study relationships between soils evolution, la...

Quantifying bedrock weathering rates under diverse climate conditions is essential to understanding timescales of landscape evolution. Yet, are often difficult constrain, and associating a weathered landform specific formative environment can be complicated by overprinting successive processes temporally varying climate. In this study, we investigate three sites between 59°N 69°N along the Norw...

abstract geosystems or geomorphic systems include terrain structure with processes interactions that work as alone or common and create a series of terrain unites. geosystem elements consist of lines, points, surfaces, and volumes. the ways of relationships between the elements form spatial structure identity. the elements prepare spaces for different land uses, when they are located in ratio t...

“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...

Alluvial fans are one of the most important of types of geomorphic landforms in mountainous regions, especially in dry and semi-dry region, which flow processes create them with reducing the slope and opening the valley after leaving the mountain.This study investigate the effects of geographic directions on the dimensions of alluvial fans in down streams in Shirkouh Mountain in the central par...

We present the first extensive high-resolution glacial geomorphic map west of Andean Cordillera in southernmost Chile (52.8–53.1°S, 73.0–73.9°W). The extends over 1565 km2 and is based on satellite images aerial photographs. At selected locations, remotely mapped geomorphology was corroborated by field observations. study area dominated erosional landforms (77%) depositional (23%), with publish...

The world’s arid lands are some of the most beautiful landscapes on Earth, and their paucity of vegetation often makes it possible to see landforms and structures with great clarity (Figure 1.1). In addition, they have many characteristics both in terms of landforms and geomorphological processes that render them different from other major environments (see, for example, Laity, 2008; Parsons an...

An important paradigm in geomorphology is paraglacial sedimentation, a phrase first used almost 40 years ago to describe reworking of glacial sediment by mass wasting and streams during and after continental-scale deglaciation. The concept has been extended to include nonglacial landforms and landscapes conditioned by glaciation. In this paper we apply the paraglacial concept to volcanoes in so...

In tectonically active mountain ranges, the landscape is shaped by interplay of erosion/sedimentation and driven crustal deformation. Characteristic landforms such as moraines, wind gaps, fault scarps, river terraces can be used to decipher evolution. However, available data often allow for different interpretations. Here we study Pradol (Pradolino) Valley in Western Slovenia, a deeply incised ...

Landforms with characteristic flow-like morphology are distributed across the southwestern portion of Utopia Planitia, Mars. Although some features have previously been interpreted as mud flows associated a former presence partly frozen muddy ocean based on their morphologies and similarities terrestrial analogues (Ivanov et al., 2014, Icarus 228; Ivanov 2015, 248), such interpretations remain ...
