Gravity erosion is one of the most important types soil in loess region, and it focus difficulty current research region. This paper systematically reviews progress gravity experimental observation methods, occurrence critical conditions, relationship between watershed water sediment, process simulation so on, It points out that lack monitoring capacity caused by random, sudden rapid characteri...

A cyclical pattern can be observed in the central sector of the Guadix Basin (southern Spain) in the Late Pliocene-Quaternary alluvial fan deposits prograding into its axial valley. A climatic significance has been attributed to this cyclicity on the basis of sedimentological and preliminary isotopic studies. The progradation phases of the alluvial fans are here attributed to more arid time int...

Tibetans view the environment as an interrelated balance upon which humans and nature coexist. Overconsumption of resources is discouraged, and the taking of life is forbidden by Buddhist practice. However, as traditional people meet the modern world, checkerboard patterns are carved into forested mountain slopes, pollution runs freely in once pristine waters, erosion lays grasslands bare, and ...

This research determines which of the phenomena that appear during cavitation are responsible for the erosion of some brittle water soluble materials, such as gypsum and alum, when exposed to a high intensity ultrasound field over the cavitation level. The observation that gypsum suffers no erosion under the effect of an ultrasound field when the material is irradiated in a saturated solution o...

soil erosion is one of the most important forms of land degradation that threatens continued and sustained agricultural production in ghana. the most severely affected areas are the three northern regions especially upper east region, where large tracts of land have been destroyed by water erosion leading to soil depth reduction and decline in soil fertility. this study was carried out in talen...

risk assessment of soil erosion, one of the most important land degradation problems worldwide, is very essential for land and water resources management, and development of soil conservation methods. in the present study, the temporal changes of soil erosion risk were assessed from 1987 to 2010, based on the revised universal soil loss equation (rusle) using remote sensing (rs) and geographic ...
