“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...

The objective of this study is to understand the effect of landslides on the drainage network within the area of interest. We thus test the potential of rivers to record the intensity of landslides that affected their courses. The study area is located within the Zagros orogenic belt along the border between Iraq and Iran. We identified 280 landslides through nine QuickBird scenes using visual ...

The character and distribution of cooling ages in modern river sediment provide useful constraints on rates and patterns of uplift and erosion within actively deforming mountain ranges. Such sediment effectively samples all locations within the catchment area, irrespective of remoteness. We evaluate how successfully detrital cooling ages may be used to constrain hinterland erosion rates by exam...

The hydrological information derived from a digital elevation model is very important in distributed modeling. As part of alpine research on stream network modeling using remote sensing data the northeast Tibetan Plateau, three (DEM) datasets were obtained for purpose features, mainly including channel network, watershed extent and terrain character. sources include airborne light detection ran...

The development of a linear mixed model to describe the degradation friction on flexible road pavements be included in pavement management systems is aim this study. It also aims at showing that, network level, factors such as temperature, rainfall, hypsometry, type layer, and geometric alignment features may influence throughout time. A dataset from six districts Portugal with 7204 sections wa...

[1] The abundance and size distribution of lakes is critical to assessing the role of lakes in regional and global biogeochemical processes. Lakes are fractal but do not always conform to the power law size-distribution typically associated with fractal geographical features. Here, we evaluate the fractal geometry of lakes with the goal of explaining apparently inconsistent observations of powe...

By subtracting surface topographies from 1979, 1994, 2000 and 2008, we measured ice thinning rates increasing from 1 m a-1 (1979-1994) to more than 4 m a-1 (2000-2008) on the tongue of the Mer de Glace. The relative contributions of changes in surface mass balance and ice fluxes to this acceleration in the thinning are estimated using field and remote sensing measurements. Between 1979-1994 and...

The rapid development of remote sensing technology for obtaining high-resolution digital elevation models (DEMs) in recent years has made them more and widely available allowed to be used morphometric assessment concave landforms, such as valleys, gullies, glacial cirques, sinkholes, craters, others. aim this study was develop a geographic information systems (GIS) toolbox the automatic extract...

For the area of historic centre Krakow (area 9.29 km2), southern Poland, base maps were prepared showing hypsometry and distribution landforms in historical variant (ca. 1000 AD) current variant, based on published data mainly from archaeological geoengineering research carried out for last 60 years, including geographic information system (GIS) tools. The aim work is to establish changes undul...
