Monitoring of an urban level spreader as part of the collaborative adaptive management process
… The Hinkson Creek CAM (Collaborative Adaptive Management) approach is doing long-term monitoring of a level spreader system in the Hinkson Creek watershed to determine the effectiveness of this stormwater best management practice (BMP) as a method to regulate flow in asmall tributary to Hinkson …

A multiperiod linear programming model of farm growth and bmp adoption in southeastern Virginia
Firm growth and best management practice (BMP) adoption of a representative, diversified, southeastern Virginia, farrow to finishing hog farm is examined in a multi-period linear programming framework. Specific attention is focused on the acquisition of additional productive resources and the …

Effect of a Water Treatment BMP on Nutrient Spiraling and Leaf Litter Breakdown in an Urban Stream
… as nutrient attenuation and carbon processing. A best management practice (BMP) water facility was installed to restore an impaired urban stream in Columbus, GA. This study was conducted to determine the effect of this BMP on nutrient spiraling and leaf litter decomposition in a 2 km stretch of …

Analysis of an Urban Stormwater Bioretention Management Practice in Prince William County, Virginia
… performance of an urban stormwater bioretention management practice in the Kingsbrooke Subdivision of Prince William County, Virginia was examined over a one-year period. Bioretention is a relatively new urban stormwater best management practice (BMP) intended to mimic the pollutant-removal …

Impact of Biochar Amendment, Hydraulic Retention Time, and Influent Concentration on N and P Removal in Horizontal Flow-Through Bioreactors
… drivers of this deterioration, and require management. In the mid-1990s, denitrifying bioreactors (DNBRs), a subsurface, edge-of-field best management practice (BMP) that intercepts and treats agricultural drainage by supporting nitrate-attenuating denitrification with a saturated, …

Sediment Delivery from Reopened Forest Roads at Stream Crossings in the Virginia Piedmont Physiographic Region, USA
… crossing approaches with diverse intensities of best management practice (BMP) implementations for surface cover and water control. Model predictions from the Water Erosion Prediction Project (WEPP) were compared to field observations of surface runoff and sediment delivery to evaluate model …

NUTRIENT RETENTION BY RIPARIAN FORESTED BUFFERS IN WESTERN MARYLAND: DO THEY WORK AND ARE THEY WORTH IT?
Riparian buffers are a best management practice (BMP) implemented to improve water quality. In 1997, Maryland established the Conservation Reserve Enhancement Program (CREP) to give landowners incentives to install riparian buffers that would help restore the Chesapeake Bay. Although many studies …

Evaluating Best Management Practices For Minimized Pesticides Transport With The Wepp-Ui Model
Best management practice (BMP) tools that provide site-specific water quality suggestions with limited input data are needed to assist consultants and farm advisors as they work to target BMP placement and reduce dissolved and sediment bound pesticide loads from agricultural landscapes. BMP …

Agricultural BMP Placement for Cost-effective Pollution Control at the Watershed Level
… development of an optimization procedure for best management practice (BMP) placement at the watershed level. The procedure combines an optimization component, written in the C++ language, with spatially variable nonpoint source (NPS) prediction and economic analysis components, written in the …

Constructed Floodplain Wetland Effectiveness for Stormwater Management
… of Opequon Creek in Northern Virginia as a best management practice (BMP) for stormwater management. The research goals were to 1) determine if wetland hydrology existed and quantify the role of groundwater exchange in the constructed wetland (CW) water budget, 2) estimate wetland hydraulic …

Application of the Analytic Hierarchy Process Optimization Algorithm in Best Management Practice Selection
The efficiency of a best management practice (BMP) is defined simply as a measure of how well the practice or series of practices removes targeted pollutants. While this concept is relatively simple, mathematical attempts to quantify BMP efficiency are numerous and complex. Intuitively, the …
-
Soil Erosion from Forest Haul Roads at Stream Crossings as Influenced by Road Attributes
… 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 provide a quantitative assessment of sediment production and potential sediment delivery from forest haul …

Modeling Watershed-Wide Bioretention Stormwater Retrofits to Achieve Thermal Pollution Mitigation Goals
… likely to be cooled naturally. While several best management practices, including bioretention filters, have been able to reduce thermal pollution, success has been limited. The extent of thermal mitigation required to prevent ecological damage is unknown. A calibrated runoff temperature model …

MODELING IMPACTS OF CLIMATE CHANGE AND AGRICULTURAL MANAGEMENT ON WATERSHED OUTPUTS IN MIDWESTERN USA
… data such as LULC, soil, crop rotation and other management data were processed through these HRUs. The SWAT model was then calibrated/validated for the Raccoon River watershed in Iowa for 2002 to 2010 and the Big Creek River watershed in Illinois for 2000 to 2003. SWAT was able to replicate …
