Recently, Korea is concentrating his concern to restoration of stream because its water quality has been deteriorated by various pollutants generated through urbanization and industrialization. As a test section, upstream section(3.1㎞) of Osan Stream which has the characteristics of the typical small urban stream was restored with natural form by various construction methods. This study was performed to understand the variation of water quality for the section after restored to natural form and to estimate improvement effectiveness of water quality by it through comparison of water quality before and after constructed. Based on the results, it was estimated that, even though inflow of tributaries, water quality was improved at the section of OS1 and OS3 and this was influenced by self-purification increased. Through the comparison with the datum of 1996, we could know that water quality after construction was greatly improved. Therefore naturalization form of Osan Stream contributed to purification of water quality and to restore stream with natural form was estimated as a desirable method for improvement of stream water quality.

본 연구에서는 최근 환경재료로서 관심이 모아지고 있는 다공성 콘크리트를 하천구조물(보 및 하상재료)에 적용함으로써 수질을 개선하고자 수행하였다. 먼저, 물리·화학적 특징을 평가해 본 결과, 공극률 10% 및 30%의 다공성 콘크리트의 압축강도는 일반 콘크리트의 최저 압축강도(180 kgf/)를 상회하여 하천구조물에 적용 가능하였고, 알칼리 용출에 의한 부착 미생물에의 영향도 거의 없을 것으로 판단되었다. 또한, 일반 콘크리트와 다공성 콘크리트로 하천구조
