Hydraulic Performance of Porous Sediment Control Structures
… of filter fabric and rockfill as well as their sediment trapping efficiency are studied in this research. The head-discharge relationship for filter fabric has been developed by first applying the Bernoulli equation to a single opening and then extending the principle to the entire …

Sediment Control In Alluvial Rivers Using Simulation-Based Optimization
… and fluvial geomorphology. Severe sediment erosion such as in-stream sever bed and bank erosion or gullying can threaten the stability of in-stream hydraulic structures, river banks, levees, and underground utilities. On the other hand, large amounts of sediment deposition can …

Evaluation of check dams for sediment control on disturbed land surfaces
An erosion and sedimentation study was conducted and the University of Illinois at Urbana-Champaign to evaluate the suitability of using check dams as an erosion control practice on military bases. Military readiness and effectiveness is enhanced by constant training and use of their lands; this …

Evaluation of sediment control practices for perimeter barrier: Experiments and modeling
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

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 …

Development of a research and demonstration facility for the evaluation of stormwater runoff, erosion control, and sediment control best management practices
… products are available for erosion and sediment control, there is currently a deficit in objective quantitative performance evaluations of such products under an adequate range of locally relevant climate conditions and soil types. To address these concerns, an Erosion Control Research …

Controlling nonpoint pollution in Virginia's urbanizing areas: an institutional perspective
… enforcement of nonpoint source (NPS) pollution control measures in the state's urbanizing areas. The institutional framework is developed primarily around the existing governmental framework. The federal, state and local roles are examined in terms of the relevant legislative and executive NPS …

The impact of nonpoint source pollution from mining wastes on water quality, Elko County, Nevada
… of dissolved constituents was found to be controlled by river discharge. Many of the deleterious impacts commonly associated with mine wastes, such as acidification and increases in suspended sediment concentrations were not found to be occurring at the site, due to factors such as …

Evaluation of Natural Remediation Following the Occurrence of a Construction-Related Sediment Plume at Camp Shelby Training Site, Mississippi
… and recovery of an anthropogenic induced sediment infill of a bottom land hardwood wetland at Camp Shelby Training Site (CSTS) in Perry and Forrest Counties, Mississippi. Lack of sediment control structures (sediment fences and matting), combined with high rainfall, led to erosion within …

Areal Modeling of Erosion for Environmental Nonpoint Applications (AMEENA)
Erosion and sediment delivery from upland areas to waterbodies is a major problem impacting water quality in the United States and elsewhere. Measures to reduce these impacts are either targeted at reducing erosion on-site or at reducing delivery of sediment to waterbodies. AMEENA (Areal Modeling …

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 …

Soil Erosion and Modeling Following Closure Best Management Practices for Bladed Skid Trails in the Ridge and Valley Region
Sediment is a prevalent non-point source pollutant associated with forest operations. Roads and skid trail surfaces have erosion rates that are greater than the harvest area. Forestry best management practices (BMPs) have been developed to minimize erosion on skid trails, but few projects have …

Improved dynamics modelling for drainage sediment prediction and management
… in this thesis aims to further knowledge of sediment behaviour and provides engineers with appropriate tools and methods to facilitate proactive sediment management. The techniques developed during this investigation are therefore able to predict the locations and quantities of sediment …

Soil Erosion from Forest Haul Roads at Stream Crossings as Influenced by Road Attributes
… and stream crossings can be important sources of sediment in forested watersheds. The purpose of this research was to compare trapped sediment and forestry best management practice (BMP) effectiveness from haul road stream crossing approaches and ditches. The three studies in this dissertation …

Impacts of artisanal and large scale gold mining on tropical rivers in West Africa: A case study from the Brong Ahafo Region of Ghana
… LSM impacted the respective river’s water and sediment quality, macroinvertebrate and microbial (Archaea and Bacteria) community structures and resulted in mercury biomagnification in fish. ASGM impact on river water and sediment quality was determined using a reversed BACI (Before/After and …

Sedimentation ponds and their operation in stormwater systems
The efficacy of sedimentation ponds as a means of sediment and heavy metal remediation is investigated, with particular regard to the physical and chemical conditions that may lead to remobilisation of metals from the sediments

A study of aquatic sedimentation in Chattanooga, Tennessee, using GIS and remote sensing technology integrated with hydrodynamic and watershed models
Suspended sediments can have benefits and drawbacks on aquatic ecosystems depending on the concentrations. The need to quantitatively monitor water bodies and watersheds is key to reduce excessive suspended concentrations. This study aims to integrate remote sensing technology with numerical …
