Better understanding the fate of atmospheric carbon (C) captured by plant photosynthesis is essential to improve natural C flux modelling. Soils are considered as major terrestrial bioreactor and repository C, whereas channel networks floodplain rivers collect transport, throughout aquatic continuum, a significant part primary production until its export through outgassing or sequestration in m...

Construction of six large dams and reservoirs on the Missouri River over the last 50-75 years has resulted in major landscape changes and alterations in flow patterns, with implications for riparian forests dominated by plains cottonwood (Populus deltoides). We quantified changes in land cover from 1892-1950s and the 1950s-2006 and the current extent and age structure of cottonwood forests on s...

The ruins of the Medieval castle and village El Castellar are located on an abrupt 1.2-km-long scarp Miocene gypsums, in central sector Ebro depression. remains main perched a 100 m cliff River. Considering historical geoarchaeological relevance settlement, this investigation aimed to study geomorphological paleoenvironmental context site during after settlement its later evolution, including c...

The effects of erosion, avalanching and random precipitation are captured in a simple stochastic partial differential equation for modelling the evolution of river networks. Our model leads to a self-organized structured landscape and to abstraction and piracy of the smaller tributaries as the evolution proceeds. An algebraic distribution of the average basin areas and a power law relationship ...

gully erosion constitutes a major problem in natural resources management and soil conservation, which causes severe land degradation in arid and semi-arid areas. therefore, determination of gully prone area and identification of gully conditioning factors can help to managers and decision makers to reduce the hazard of gully erosion. the aim of this study is to predictthe gully erosion suscept...

Tropical forests are the only forest biome to have experienced increased rates of forest loss during the past decade because of global demands for food and biofuels. The implications of such extensive forest clearing on the dynamics of tropical river systems remain relatively unknown, despite significant progress in our understanding of the role of trees in riverbank stability. Here, we documen...

by determining relative importance and contributions of erosion types to sediment yield, erosion susceptible areas in a watershed will be identified, and sediment control and soil conservation projects can be focused on that areas. because of many problems associated with traditional procedures for identifying sediment sources, fingerprinting techniques, based on physical, chemical and organic ...

Abstract Landslides have occurred on the Belimbing road, Pejagoan, Kebumen – Central Java which has affected 4 houses. The direction of landslide movement is N10 ° E, with rotational type. lithology location river deposits that not been compacted (alluvium). Morphology plain steep bordering Luk Ulo river. slope 45 60 a shape influenced by lateral erosion result analysis groundwater flowing arou...

introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...
