Evaluation of field performance of BEST aeolian sediment catcher in sandy-loam soil of arid zone of Turkey
sediment trap trap efficiency wind erosion
2017/6/26
Field measurement of wind erosion is still a great challenge for researchers. In this study, field performance of a newly designed sediment trap BEST (Basaran and Erpul Sediment Trap) was evaluated fo...
Scale effects of eroded sediment transport in Wujiang River Basin, Guizhou Province, China
Sediment transport modulus Scale effect Soil erosion Wujiang River Basin
2018/3/23
In recent years, research on spatial scale and scale transformation of eroded sediment transport has become a forefront field in current soil erosion research, but there are very few studies on the sc...
AN APPROACH TO QUANTIFY SEDIMENT YIELD IN VAST AREAS
Watershed Sediment Yield Index (SYI) Remote Sensing Technology
2015/8/17
Loss of fertile soil by erosion is undoubtedly much higher than weathering and soil formation. A
number of studies on estimation of sediment yield have been conducted and many such studies will be p...
Land Use Changes and Sediment Yield on a Hilly Watershed in Central-East Argentina
GIS MUSLE soil loss territorial management
2015/7/28
Watershed management strategies need suitable techniques to be available in order to quantify sediment yield,
among other relevant issues. The aim of this work was to estimate the sediment yield on ...
Evaluation of the variability in runoff and sediment loss in successional fallow vegetation of Southern Nigeria
erosional losses soil erosion rainfall vegetation components vegetation fallows
2015/3/10
The effects of three different ages of natural fallow vegetation on runoff and sediment loss were investigated in a part of the rainforest zone of Nigeria. Measurements of runoff amount and sediment l...
Assessing sediment enrichment ratio in Mai-Negus catchment, northern Ethiopia
degradation erosion-status sites landform
2015/3/10
Soil degradation is a threat to sustainable development in Ethiopia. However, degradation indicators, such as sediment enrichment ratio (SER), are not adequately documented in literature. This study a...
Evaluation of the relationships between runoff-rainfall-sediment related nutrient loss (A case study: Kojour Watershed, Iran)
clockwise hysteretic loop organic matter phosphorus loss regression models suspended sediment
2015/3/9
Suspended sediment (SS) resulted from distributed soil erosions facilitates soil organic matter and phosphorus (P) transportation and influences soil depletion and water quality. Organic matter (OM) i...
Temporal variations of runoff and sediment in different soil clay contents using simulated conditions
clay erosion plot rainfall simulator
2015/3/9
Soil clay content (SCC) plays an essential role in the processes of infiltration, seal and crust formation, runoff, and soil erosion. The role played by SCC in water erosion has received much attentio...
Use of trace elements from historical mining for alluvial sediment dating
archaeological methods heavy metals historic metallurgy human impact landscape development Middle Ages
2015/3/9
We examined whether it is possible to relate concentrations of trace elements in alluvial sediments with records concerning the intensity of mining, and use them as a means of dating. We conducted our...
Storm-wise sediment yield prediction using hillslope erosion model in semi-arid abundant lands
abundant lands erosion model hillslope erosion model (HEM) Iran Khosbijan Research Centre
2015/3/9
Evaluation of soil erosion by existing models is needed as an important tool for managerial purposes in designation of proper water and soil conservation techniques. The present study aimed to assess ...
Effect of temperature on the distribution of polycyclic aromatic hydrocarbons in soil and sediment
sorption desorption thermodynamic parameters polycyclic aromatic hydrocarbons
2015/2/4
The knowledge of sorption-desorption processes of polycyclic aromatic hydrocarbons (PAHs) in natural solids is essential to predict the fate, transport, and environmental risks of these pollutants. In...
Sediment Load and Suspended Sediment Concentration Prediction
sediment concentration sediment yield sediment delivery ratio soil erosion water quality European catchments
2015/1/28
Sediment is a natural component of riverine environments and its presence in river systems is essential. However, in many ways and many places river systems and the landscape have been strongly affect...
Soil reinforcement by a root system and its effects on sediment yield in response to concentrated flow in the loess plateau
Root Soil Properties Soil Erosion Sediment Yield Loess Plateau
2013/3/4
The importance of roots in soil conservation has long been underestimated due to a lack of sys-tematic studies conducted to evaluate root dis-tribution patterns and their effects on soil ero-sion. Cur...
Ultra-fine Coatings on Sediment Grains Influence Nitrate and Sulfate Storage in Soil
Ultra-fine Coatings Sediment Grains Nitrate and Sulfate Storage Soil
2009/12/16
Tiny sediment grains are covered with a very fine-grained, complex mixture of minerals in an open fabric that results in a large surface area in contact with water between the grains. Scientists at th...
