Systems Analysis Applied to the Protection and Enhancement of the Water Quality of Lake Macbride

摘要

This study reports on the development of an optimization model to determine strategies for controlling the impact of land runoff on lake water quality. An Iowa agricultural watershed, and Lake MacBride were analyzed. It was found that the lake was a stratified eutrophic lake. Phosphorus was the limiting nutrient in early summer with nitrogen becoming limiting in the early fall. The optimization moden indicated that runoff control of up to 75% will result in enhanced water quality.
