- Abstract
- Anyang Stream including its main branch is the most big branch stream of Han River in Korea. The geological and geomorphological characteristics investigated to the affected area of Anyang Stream, in which rainfall characteristic analyzed. The water quality surveyed that the analysis of water pollution used to biotic index and biological water pollution.The rainfall pattern in this area was like to that of typical Korea, but the rate of trigger and runoff during summer season(June~August) is more higher than mean of Korea. A dried stream is severe status, which was due to abundant runoff. After 1997, water quality of stream is recovering status such as water pollution of stream steeply decreased. Although, owing to the increasing of a T-N and SS at upstream wastewater were due to bad collection of industrial factories, livestock's and mans living, the water quality worsted at upstream. Water quality in total section of main stream was severely contaminated that water-quality limit is 5 with polysaprobic by water self-purification. That of main branch was 1~3limits with α- and β-mesosaprobic in Anyang city area, But water quality in all area about another branch of Anyang stream except Anyang city area was almost under of 3 grades. Though trying of Anyang city for recover movement on Anyang stream, water pollution states of upper branch in Anyang stream was not better than its of 2002.
