This study focused on the sediment reduction effects of VFS (vegetative filter strip) systems for the general characteristics ofuplands in Korea. General conditions of upland fields were investigated through national scales of annual agricultural statistics. 7-15 %of slope with loam soil was the dominant types of uplands, and the hydrologic soil group feature usually belong to Type B. Thecommon sizes of uplands were bigger than 0.1 ha and less than 0.2 ha, and 86.2 % of them account for less than 1.0 ha. With thisinformation, 0.1 ha, 0.5 ha, and 1.0 ha of uplands with various shapes and 7-15 % of slopes were considered for the VFS systemsimulations. 20 mm, 40 mm, and 100 mm of daily precipitation were applied. As a result, the trapping efficiencies of VFS systemswere obtained 37.4～100 % for 7 % slope and 18.1～98.0 % for 15 % slope of the less than 1.0ha of uplands. As rainfall increased,sediment loads also increased with slope and slope length increase. Also as size and slope of uplands and slope length increased withVFS length decrease, the trapping efficiency decreased for the same amount of rainfall. The optimum lengths of VFS systems for thegivien upland conditions were suggested based on the modelling results with condition of VFS length less than 20 % of upland areas.
