ABSTRACT |
A long-term nationwide nonpoint-source pollution monitoring program was initiated by the Ministry of Environment Republic of
Korea (ME) in 2007. Monitoring devices including rain gauges, flow meters, and automatic samplers were installed in monitoring sites to
collect dynamic runoff data in 2008-2009. More than 10 rainfall events with three or more antecedent dry days were monitored per year.
More than 10 samples were collected and analyzed per event. So far, five land use types (single family, apartments, education facilities,
power plants, and other public facilities) have been monitored 23 to 24 times each. Characterization of the runoff from different land
use types will aid unit load estimation in Korea and hopefully in other countries with similar land use. The monitoring results will be
reported regularly at national and international levels. |
