"Effectiveness of Wetlands as a Best Management Practice for
Agriculture" is a project that aims to quantitatively assess the
effectiveness of constructed wetlands for providing water
quality improvement under various agricultural scenarios.
Collection Organization: Texas A&M University
Collection Methodology: Six experimental wetlands cells ... constructed to provide shallow flow through aquatic vegetation
to remove pollutants from surface runoff from an
agricultural/industrial watershed. Cells, each 30 ft. by 100 ft.
in surface area, arranged in two rows of 3 to provide
opportunity to study water quality benefits. The cells uniformly
planted with appropriate plants so vegetation not a variable.
Water pumped into the cells at predetermined flow rates.
Hydraulic and pollutant loading studied as experimental
variable. Inflow and effluent water sample analyzed for total
suspended solids, volatile suspended solids, nitrate, ammonia,
total nitrogen, phosphorous and biochemical oxygen demand
removal. Field data used to validate a computer model describing
the transport of contaminants within wetlands.
Collection Frequency: Ongoing
Update Characteristics: N/A
