This paper presents basic data to management of nonpoint source. Follow as the result of analysis of water pollution characteristic;
Because forest and agriculture area are distributed all over Nae-sa stream watershed which is small watershed, so reach time is 1~2hr. Within 1~2hr from the time that primary rainfall occurred , concentration of BOD is 2~6 times higher than it's of dry season on Site 1 and Site 2. We can get the study that a lot of nonpoint sources enter the channel by primary rainfall
