Abstract

This study aimed to evaluate stream environments of Gaeumjeongcheon and Bansongsohacheonin the City of Changwon, Gyeongsangnam-do, on the basis of the evaluation of each streamstructure, stream faunae and florae, the evaluation of stream naturalness, and the results ofmonitoring of water quality. Stream survey was conducted quarterly for a year, and five surveysincluding a pre-survey were conducted. Given the nature of urban streams, most of streams wereequipped with artificial embankments with a narrow width of under 25m, and the vertical slopewas very gentle. Except for the summer rainy season, the flow was small, and also the flow ratewas very slow due to drop and river structures. In terms of florae, Gaeumjeongcheon had 24families and 59 species, while Bansongsohacheon had 20 families and 47 species. In the survey offaunae, in Gaeumjeoncheon, only fish presumed to be mud fish were collected, and such birds ascranes and spot-billed ducks, and salamander larvae, Lymnaea auricularia, etc. were observed. Inthe evaluation of stream naturalness targeting the entire stream section, Gaeumjeongcheon wasevaluated as class Ⅲ, and Bansongsohacheon as class Ⅳ, revealing that Bansongsohacheon naturalness was low. Seven items related to river water quality were analyzed, revealing thatduring the dry season when the flow was reduced and the flow rate was slow, the water qualityturned poor. In particular, due to winter's continued drought, the stream quality at the fourthsurvey was found to be the poorest, and Bansongsohacheon had a severer pollution level thanGaeumjeongcheon.
