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...
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...
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...
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...
