Efficient Setting of Riparian Buffer Zone to Reduce Non-Point Pollutant

Abstract

For control of non-point pollutants in Han River, the required method to become with nature is riparian buffer zone (RBZ) or riparian buffer waterside. RBZ is habitats of living organism and it is to improve water quality setting up and management. But the study of riparian buffer zones has not been achieved yet. The object of the study is to establish efficient setting of riparian buffer zone for increase of self-purification, ability to intercept non-point pollutants and preservation of habitats of living organism. The study focused on existing experimental site's development and complement. Experimentation and analysis of removal effect of non-point pollutants has also been preceded. A location of the Experiment is Nam Han River (Byung San-Ri, Yang Pyong-Gun, Gyeong Gi-Do) which is included in Han River water system. The area was divided into 5 land cover sectors: grass, reed, pussy willow, mixed (grass + pussy willow) and natural zone to compare effectiveness of vegetation. Water samples from four points and samples each sector have been collected in different widths and depths (4 points in each sector). And the pollutant removal efficiency by sectors with different plant species was yielded through influent with one of each sample.
