During the dry periods, many types of pollutants are being accumulated on the land surface and the accumulated various pollutants are inflowing in th the near watershed areas for the rainfall periods. Then, the monitoring study needs to analysis of the pollutant loads and an establishment of a management plan for nonpoint source. The aims of this study are the characterization of discharge from nonpoint source, the analysis of the pollutant loads and an establishment of a management plan for

... point source of Geum river basin. For this purpose, 7 monitoring points was selected to the investigated. During the period from April, 2008 to August, 2013, the water automatic sampler system has been installed in each monitoring points. Event Mean Concentration(EMC) of BOD 5 , SS was calculated based on the monitoring data of 318 rainfall events at 7 monitoring points. The land use of the studied basins were divided into forested land and grassland. As the results, a significant relationship was observed from the correlation between EMCs and rainfall characteristics. The present study is achieved to provide the correlation between rainfall events and nonpoint source pollutants. And the data which were build up in this study will contribute to establish the management policy for the nonpoint source pollutants.
