Characteristics of Pollution Source Structures and Temporal and Spatial Discharge from the Drainage Basin of a Reclaimed Area

간척지 담수호유역의 오염물질 배출구조 및 시공간적 유출특성

Discharge characteristics of organic materials and nutrients were estimated in the catchment area of relaimed area-Saemankeum-. Discharge load of BOD5 was high in the domestic system, while nitrogen and phosphorous were discharged mainly from the livestock system and the land . Load was so dependent on the precipitation that it increased in the rainy season, particulary in nitrogen and phosphorus. Loads from nonpoint sources in this area were higher compared with others.
