Non-point pollution is caused by many diffusive sources, unlike a point pollution derivedfrom industrial wastewater treatment plants or sewage treatment plants. Runoff of non-pointpollutants is originated from rainfall or thawing in short period of time moving over andthrough the a ground surface. They cause ill effect on the quality of neighboring aquaticenvironment. To prevent effectively the wash off from non-point pollutant, it should beimmediately reduced at the source or be treated after gathering of runoff water. This study hasbeen carried out for the best width of riparian buffer zone. So we implemented the experimentin terms of its depth, width and kind of vegetations and calculated the reduction of pollutantsloading. The experimental zone encompasses the watershed of Namhan River (KyunggidoYangpyunggun Byungsanri). The region was divided into 5 land cover sectors : grass, reed,pussy willow, mixed(grass+pussy willow) and natural zone to compare effectiveness ofvegetation. Water samples from four points have been collected in different depths. And thepollutant removal efficiency by sectors with different plant species was yielded throughinfluent with one of each sample. And we obtained the correlation between the width ofriparian buffer zone and the removal efficiency of pollutants. Using correlation result, the widthof riparian buffer zones which needs to improve the water quality of river could be derived.
Abstract
Non-point pollution is caused by many diffusive sources, unlike a point pollution derivedfrom industrial wastewater treatment plants or sewage treatment plants.

To prevent effectively the wash off from non-point pollutant, it should beimmediately reduced at the source or be treated after gathering of runoff water. This study hasbeen carried out for the best width of riparian buffer zone.
