Erosion control with vegetation in highway corridors
… vegetation and land contours, thereby causing erosion and pollution. Minimizing erosion is predicated on the principle of maximizing water infiltration to reduce massive runoff of water. This depends on grading and soil preparation methods, augmented temporarily by mulches, but perfected by …

Roadside Ditch Design and Erosion Control on Virginia Highways
… for the Virginia Department of Transportation. Erosion failures of roadside ditches have occurred frequently enough to indicate that it may be desirable to revise the current design practice. Through the Virginia Transportation Research Council, VDOT has sponsored this research to investigate …

A quantified approach to the functional longevity of Geosynthetic Rolled Erosion Control Products (GRECPS)
Geosynthetic Rolled Erosion Control Products (GRECPs) have been utilized for decades in a multitude of applications to mitigate erosion resulting from land disturbance in civil construction projects. GRECPs vary from one type to another, ranging in performance and design life due to their …

Simulating the Adoption of Soil Conservation Management Systems Under the Conditions of Uncertainty (Erosion, Control)
… concern for the continuing problem of soil erosion. Since conservation involves a planning horizon of more than one year, risk and uncertainty enter into the plans. Over time it is difficult to predict farm income due to variability in prices, costs, interest rates, weather, crop yields, and …

Effect of Bacterial Strain on MICP and its Application for the Erosion Control of Fine Sands
Tangential flow-induced erosion poses a major threat to a wide variety of engineering structures, including earth-filled embankment dams and oil and gas extraction wells. Current mitigation solutions are limited to mechanical approaches (e.g. filters, gravel packs), relying on the fulfilment of a …

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 …

Assessment of Technical Efficacy and Economic Impact of Bench Terraces used in Soil Erosion Control in Eastern Rwanda
Soil erosion is one of the most serious problems challenging the wellbeing of the human beings and environmental sustainability. In developing countries like Rwanda, in order to combat soil erosion, conservation practices should be implemented. This research evaluated the technical conformity and …

Evaluation of Best Management Practices for Bladed Skid Trail Erosion Control and Determination of Erosion Model Accuracy and Applicability
… the majority of sediment is produced from erosion on highly disturbed areas, such as skid trails, haul roads, and log landings. Erosion from silvicultural activities not only has the potential to introduce sediment into waterways but can also decrease site productivity through the removal …

Development of a research and demonstration facility for the evaluation of stormwater runoff, erosion control, and sediment control best management practices
… rates and volumes of stormwater runoff and soil erosion. Soil erosion is a major global environmental problem and the fourth leading cause of water quality impairment in U.S. Although many commercial products are available for erosion and sediment control, there is currently a deficit in …

Development of testing protocols and evaluation methods for erosion and sediment control products
A study at the Erosion and Sediment Control Research and Training Center (ESCRTC) at the University of Illinois at Urbana-Champaign was conducted to develop testing protocols for ditch checks and erosion control blankets, as well as evaluate the products’ effectiveness as erosion and sediment …

Systems analysis of runoff and sediment yield from a watershed using a simulation model
… levels of conservation management and, instream erosion control structures for long term analysis. Temporal and spatial variations of a rainfall event were also considered so the response of the watershed can be accurately modeled. Channel processes were incorporated into a comprehensive model to …
