2001) compared the pre- and post-implementation responses of best management practices on sediment, nitrate, and P losses from the Nomini watershed in the Coastal Plain area and found the effectiveness of the practices diminished because of the increased rainfall and runoff intensity
in the post-implementation phase of the project.
Many researchers believe global warming can increase rainfall and runoff intensity
, a phenomenon that could result in more surface water and groundwater contamination and environmental health problems.
It is generally accepted that contaminant accumulation is a function of time, and that the ability of surface runoff to remove accumulated contaminants increases as runoff intensity
