Urban Erosion Potential Risk Mapping with GIS
… (metals, nutrients, etc.) with it. Existing erosion models focus primarily on estimating erosion from agricultural watersheds. Methods are needed to predict areas with high erosive potential (EP) in urban watersheds. Highlighting highly erosive areas in urbanized watersheds allows for the …

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 …

Operational characteristics, erosion potential, and implementation of forestry best management practices on biomass harvesting operations
… a likely feedstock to meet increased demands. Potentials for increased biomass utilization have created concerns regarding possible impacts of using logging residues for energy. The overall goals of this project were to characterize biomass harvesting operations and to evaluate potential …

The influence of a petrochemical discharge on the bioturbation and erosion potential of an intertidal estuarine mudflat (Humber estuary, UK)
… the effects of community change on bioturbation potential. In addition, a laboratory flume was constructed to measure sediment erosion potential with field measurements being taken using a Cohesive Strength Meter (CSM). The physico-chemical properties of the sediment, changes to the infaunal …

Changes in Streambank Erodibility and Critical Shear Stress Due to Surface Subaerial Processes
… conditions and processes that enhance streambank erosion potential. The goal of this study was to investigate temporal changes in streambank erodibility and critical shear stress due to surface weathering. Soil erodibility and critical shear stress were measured monthly in situ using a multi-angle …

Investigation of Erosion and Deposition of Sand Particles within a Pin Fin Array
… on the channel walls (99.6% - 100%). The erosion potential is shown to increase with Stokes number and is highest on the pin faces. As is to be expected, the deposition increases with decreasing softening temperature from 13.4% at θ<sub>ST</sub> = 0.67 to 79% for θ<sub>ST</sub> =0. …

Identifying Locations Of Highly Eroded Agricultural Land In The Devils Lake Basin, ND Using GIS Terrain Analysis Modeling
<p>Soil erosion modeling using terrain analysis holds great potential due to the simplicity of the models, and the ease in running the analysis in a GIS. Terrain analysis of the upper Devils Lake basin was conducted using a 3-meter Light Detection and Ranging-derived digital elevation model. …

Evaluation of road erosion prediction models applied to unpaved roads in a small tropical watershed in Eastern Brazil
… sediment generation and delivery. A number of erosion and sediment prediction models have been developed for unpaved roads and applied across a wide range of locations. However, little work has been devoted to the comparison of these models or to their application in tropical environments. A 13 …

Harvesting impacts on steep slopes in Virginia
… in Virginia. Special emphasis was placed on erosion, compaction and soil movement. Ten randomly selected study areas were clear-cut between September 1988 and August 1989; measurements followed between March 1989 and August 1989. Potential erosion was estimated using the Universal Soil Loss …

Factors influencing the adoption of soil conservation practices in Virginia's Piedmont Bright Leaf Erosion Control Area
… a sample of farmers in the Piedmont Bright Leaf Erosion Control Area of Virginia is examined to determine the factors which influence the farmers' decisions to use soil conservation practices. The relationship between farmers' use of conservation tillage and other conservation practices and a …

Effects of Two-Phase Flow in a Multistage Centrifugal Compressor
… droplet impact on the compressor surfaces. An erosion model was developed and implemented to locate the erosion "hot spots" and to estimate the amount of material eroded. To understand the effects of increasing liquid carryover, the mass flow rate of the liquid phase was increased from 1% to 5% …

Quantifying Near-Bank Turbulence Through a Storm Event
… impairment for streams and rivers. Streambank erosion is a dominant source contributing to sediment pollution and there is a growing need for adopting management practices to reduce it. Bank retreat occurs from a combination of fluvial erosion, subaerial processes, and mass failure. Fluvial …

Soil erosion and land degradation in the Swartland and Sandveld, Western Cape province, South Africa : a re-evaluation
… making this area vulnerable to varying erosion rates. Land use in the Swartland and Sandveld is mainly agricultural. Soil erosion is driven by the force of wind and or water. Sheet flow is what is considered as unconstrained water erosion together with rainsplash, while piping, rill and …

Evaluating the impacts of urbanization and stormwater management practices on stream response
… always reduced to fair. Long-term changes in erosion potential in the Morgan Creek watershed were minimized when stormwater controls were applied. Biotic response was shown to be related to both hydrologic or geomorphic metric values, indicating that restoration of hydrology may not allow for …

Effect of exposure on the erodibility of intertidal mudflats
… sediments, and therefore changes the patterns of erosion/accretion on intertidal flats. Consequently, exposure indirectly affects the intertidal morphology. An understanding of how exposure alters the erodibility of sediment on intertidal flats is critical to predicting the resilience of …

Rainfall trends in India and their impact on soil erosion and land management
… 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 long …

Evaluating Energywood Harvesting Operations in The Lower Mid-Atlantic Region of the United States
… concerns surround energywood harvesting, such as potential increased erosion, applicability and adequacy of conventional water quality best management practices (BMPs), increased area in road network features due to increased machine trafficking, and reduced quantities of residual woody debris. …
