Selection and Placement of Best Management Practices Used to Reduce Total Phosphorous Runoff

An increased loss of agricultural nutrients is a growing concern for water quality in Arkansas especially in nutrient surplus areas. Methodologies that help to find solutions that are accepted and understood by all the stakeholders involved in water quality issues are needed. Several studies have shown that best management practices (BMPs) are effective in controlling excess amounts of sediment and nutrient from runoff. However, selection, placement and affordability of those practices need to be taken into consideration when making water management decisions.

The main goal of this project was to evaluate the relations between water quality, and selection, timing, and distribution of BMPs within the Lincoln Lake watershed using an environmental-economic model. This goal was accomplished by fulfilling four objectives:

  1. Integrate historical water quality, annual land use, point source, nutrient management/conservation plans and BMP data from Moores Creek, Beatty Branch, and Lincoln Lake into a common GIS-linked database.
  2. Evaluate BMPs under uncertain production conditions using stochastic dominance (SD) techniques by demonstrating how selection of BMPs differs when scenarios are ranked in terms of total phosphorous reduction or net returns benefits.
  3. Develop a BMP optimization technique that searches for near optimal solutions to achieve minimum total phosphorous pollution runoff and minimum total net cost increase for BMP placement within the Lincoln Lake
  4. Collect stakeholder’s perceptions about water quality and sources of water pollution.
