Characterizing soil erosion potential using electrical resistivity imaging
The erosion rate, or erodibility, of soil depends on many soil characteristics including: plasticity, water content, grain size, percent clay, compaction, and shear strength. Many of these characteristics also influence soil in situ bulk electrical resistivity (ER) measurements. The objective of …

Optimizing the management of soil erosion using GIS
The dynamic nature of erosion and associated processes and their dependence on climatic, pedological, land cover, land use, and management factors result in spatial and temporal variability. Computing and mapping this variability will produce information which is essential for designing dams, …

Effect of water temperature on cohesive soil erosion
… the<br />effect of water temperature on cohesive soil erosion should be explored. The objectives of this study are to: determine the effect of water temperature on the erosion rates of clay; determine how erosion rates vary with clay mineralogy; and, explore the relationship between zeta potential …

Modeling Soil Erosion in the Upper Green River, KY
Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease …

Simulating the Soil Erosion from Land Removed from CRP
… The objective of this study was to calibrate an erosion prediction model and use it to estimate increased soil erosion due to this land use change. The Water Erosion Prediction Project (WEPP), a process based erosion prediction model developed by USDA, was utilized in this study for this purpose. …

Soil erosion and suspended sediment dynamics in intensive agricultural catchments
… ecological habitats. Management of accelerated soil losses and the transmission of sediment-associated agricultural pollutants, such as phosphorus, is required to mitigate the drive towards sustainable intensification to increase global food security. Quantifying soil erosion and the pathways …

Soil conditioner effects on soil erosion, soil structure and crop performance
Previous work has suggested that soil conditioners can provide environmentally beneficial aids to agriculture and soil conservation. To investigate this further, studies were carried out on soil conditioner effects on soil erosion, soil structure and crop performance. The main soil conditioner …

Effects of Black-tailed Prairie Dogs (Cynomys Iudovicianus) on Soil Erosion
<p>The rates of natural erosion are poorly understood, especially with respect to influences by fauna. Soil traps were implemented in a prairie dog town 14 miles NW of Killdeer, ND to measure and compare erosion rates within the prairie dog town to those of a control site comprised of natural …

Predicting Soil Erosion on Off-Road Vehicle Trails in Southwest Missouri
… on specially designated trails since the 1960s. Soil erosion is a focal area of concern for environmental groups in the area. Methods for predicting soil erosion include the Universal Soil Loss Equation (USLE), Modified Universal Soil Loss Equation (MUSLE) and Geographic Information System (GIS) …

Development of novel lanthanide based particle tracers for rapid monitoring of soil erosion.
Soil erosion is a global problem, affecting much of the world's agricultural land. As the world's population increases, the pressures placed upon the land resource to provide space for food production, leisure, housing and industrial facilities also increases. Thus it is vital that the land …

Linking soil erosion processes with arable weed seedbank dynamics to inform sustainable cropping
<p>Accelerated soil erosion affects sustainable food production through the degradation of arable soils resulting in lower crop yields and compromising biodiversity. Over the past 50 years, the weed seedbank has been declining due to farming intensification, increased herbicide use and weed …

Rainfall trends in India and their impact on soil erosion and land management
… on the impact that climate trends may have on soil erosion and contaminant transport in India and examined the potential for top soil management practices to improve or maintain soil quality. Historical rainfall data from 50-135 years and extreme temperature data for 103 years were analysed and …

Impact of Tenure and Uncertainty on the Choice of Optimal Soil Erosion Control Measures
Soil conservation issues re-surfaced in the United States during 1970's when crop acreage expanded by more than 120 percent to meet a 132 percent rise in agricultural exports. This large rapid expansion in cropland acres generated concern that increase in soil erosion might impair the nation's long …
