Little information is available on the scale behavior of the flow–sediment relationship despite numerous studies on the scale behavior of sediment yield. Based on data observed at 19 gauging stations and 10 runoff experimental plots, we examined the flow–sediment relationship in the context of spatio‐temporal scales for hilly loess areas, China. Distinct from many rivers around the world, sediment...
Two sites (Asciano and Castelfalfi) were selected in Tuscany (central-west Italy) in order to study the effects of wild boar activities (rooting and trampling) at two different densities and on the organic matter quality and functionality in soil ecosystems. In each site, two study areas with different vegetation (woodland (W) and olive tree grove (O)) were identified to evaluate the influence of...
Geomorphological and sedimentological investigations in the lower reaches of the Orkhon River in northern Mongolia provide evidence for Late Pleistocene terraces, Holocene soil development, aeolian accumulation, soil erosion and slope wash. Optically stimulated luminescence (OSL) and radiocarbon dating of aeolian and colluvial sediments including paleosols show different sedimentation and soil formation...
Although rock check dams have been used for centuries to control erosion and support subsistence agriculture on western US rangelands, there is a lack of measured data to quantify their impact on soil moisture distribution. This study was conducted to measure and document soil moisture response to loose rock structures and wire bound rock structures in comparison with untreated control sites during...
Andisols are soils with high structural development and aggregate stability, characteristics that play a major role in their high infiltration rate. They are, however, vulnerable to environmental changes, particularly those associated with land use modifications. The present work aims to ascertain the influence of modifications to land use as well as vegetation cover on the steady-state infiltration...
Gully erosion and woody plant encroachment are frequently observed in grasslands worldwide. Gully erosion driven by water processes is usually affected by topography, land-use change and vegetation cover. We hypothesised that trees, through their potential link with overland and subsurface flow, may have an impact on gully extension. However, very few studies have simultaneously considered tree encroachment...
A rainfall simulator is an ideal tool for infiltration, soil erosion, and other related research areas for replicating the process and characteristics of natural rainfall. In this study, a laboratory-scale rainfall simulator is developed. Rainfall characteristics including the rainfall intensity and its spatial uniformity, raindrop size, raindrop velocity, and kinetic energy confirm that natural rainfall...
Globally, soils contain an estimated 1500GT of carbon, over twice that present in the atmosphere (IPCC, 2001). However the role of soils in the global carbon cycle remains highly contentious. Soil erosion redistributes organic matter (OM) within landscapes, and takes place at a range of scales from mass movement to interrill erosion. It is known that interrill erosion occurring on clay-rich stable...
This study examines the interplay between long-term climate changes, compounded natural disturbances and human driven land-use changes on catastrophic soil erosion of the heathland ecosystem of Haukadalsheiði, south Iceland. Soil erosion was catastrophic for three centuries (~1660–1960 AD) and was characterized by almost total loss of vegetation and underlying soil. Soil erosion resulted in a desertified,...
A study was undertaken into the environmental and economic impacts of different soil management strategies, spontaneous grass cover with and without gully control (SC/SCGC) or conventional tillage with and without gully control (T/TGC), based on the experimental results obtained in an 6.1ha olive crop microcatchment. Initially, 2years of rainfall–runoff–sediment load data series, (34 events) recorded...
The concentrations of Co, Cr, Cu, Mn, Ni, Pb, Zn, and V in urban topsoil samples collected from inside the Xi'an Second Ringroad, northwestern China were measured by X-ray fluorescence spectroscopy. Correlation coefficient analysis, factor analysis and cluster analysis were used to analyze the data and to identify the possible sources of these heavy metals. The results show that the mean concentrations...
Profile samples from 0 to 70cm depth were collected in five plant zones along a hydrological gradient in a typical land/inland water ecotone, Northeast China. Total phosphorous (TP), organic phosphorous (OP), inorganic phosphorous (IP) and available phosphorous (AP) were measured to study their horizontal and vertical distribution patterns in the land/inland water ecotone, as well as their important...
