- Abstract:
- ... Rainfall characteristics can be a major factor influencing the ability of best management practices to reduce nutrient loss from agricultural lands to receiving waterbodies. The goal of this study was to examine how rainfall characteristics impacted NO₃ – N concentrations in a tailwater recovery (TWR) ditch implemented at a farm within the Porter Bayou watershed in Mississippi, USA. We used a meth ...

- Abstract:
- ... Over the last several decades, increased groundwater usage by agriculture with a consequence of groundwater resource depletion has motivated the discussion of sustainability of groundwater resource. In this study, to investigate the impacts of agricultural best management practices (BMPs) on groundwater level, two kinds of conservation practices and five scenarios of tail water recovery pond and c ...

- Abstract:
- ... Best management practices (BMPs) are conservation efforts implemented to address environmental challenges associated with agricultural production. One such BMP, a tailwater recovery (TWR) system, has a dual purpose aimed at mitigating solids and nutrient losses from agricultural landscapes and creating an additional surface water source for irrigation. This study analyzes the costs of using five T ...

- Abstract:
- ... The rapid spreading of impervious areas has been a growing concern in urban stormwater management. Runoff originating from impervious areas directly connected to or disconnected from drainage systems contributes differently to the outflow at the downstream outlet. Extensive implementations of best management practices (BMPs) and low impact development (LID) practices necessitate more accurate quan ...

Nutrient enrichment is largely driven by application of nutrients and altered hydrologic regimes. To inform stressor–response‐based nutrient reduction goals for agricultural alluvial plain streams, diatom assemblages were s ...

- Abstract:

An On-Farm Water Storage (OFWS) system is a structural Best Management Practice (BMP) that prevents downstream nutrient loading by capturing irrigation tailwater and storm runoff from agricultural fields. OFWS systems, as a result, also act as a source of water for irrigation with the potential to recycle nutrients captured in runoff events. A monitoring study was conducted for an OFWS system loca ...

Reducing the amount of nitrogen (N) exported in these streams requires the use of best management practices (BMPs) within the landscape. However, proper BMP utilization has rarely been statistically connected to potential controls of N export ...

- Abstract:
- ... Constructed wetlands are a suggested best management practice to help mitigate agricultural runoff before entering receiving aquatic ecosystems. A constructed wetland system (180 m x 30 m), comprising a sediment retention basin and two treatment cells, was used to determine the fate and transport of simulated runoff containing the pyrethroid insecticides lambda-cyhalothrin and cyfluthrin, as well ...

- Abstract:
- ... In intensively cultivated areas, agriculture is a significant source of pesticides associated with storm runoff. When these pollutants enter aquatic receiving waters, they have potential to damage nearby aquatic ecosystems. Constructed wetlands are a best management practice (BMP) designed to help alleviate this potential problem. A constructed wetland system (180 x 30 m) comprised of a sediment r ...

- Abstract:
- ... Oxbow lakes are remnants of meandering floodplain rivers, which have been cut off and physically isolated from their respective main river channels. They usually capture only small relic drainages. Beasley Lake Watershed, a Conservation Effects Assessment Project (CEAP) benchmark watershed, is one of three oxbow lake watersheds in the original Mississippi Delta Management Systems Evaluation Area ( ...

- Abstract:
- ... Analyses of regional carbon sources and sinks are essential to assess the economical feasibility of various carbon sequestration technologies for mitigating atmospheric CO₂ accumulation and for preventing global warming. Such an inventory is a prerequisite for regional trading of CO₂ emissions. As a U.S. Department of Energy Southeast Regional Carbon Sequestration Partner, we have estimated the st ...

- Abstract:
- ... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...
