초록
Daecheong Lake plays a major role in securing water resources in the central region. This lake is experiencing problems due to the yearly occurrence of algae and therefore, long-term monitoring of the lake is conducted to analyze water quality and tidal characteristics. It is found that pollutants containing large amounts of nitrogen and phosphorus are scattered in the upper stream of the Okcheon Stream, which is a tributary. Cyanobacteria grow in significant quantities every year due to sewage treatment plants. We use a SWAT model to evaluate pollutant reduction for different load scenarios. Our findings generally support that Scenario 3, the Farm Management, Point Pollution Reduction and Creation of an Overland Pond method can control the pollutants most efficiently, thereby reducing the amount of nutrients that flow into the river and suppressing the occurrence of algae.
