Abstract

This study was conducted to investigate water quality after construction of straightened concrete block at Tongbok stream and difference of water quality between natural stream and municipal stream artificially straightened. In Tongbok upstream which was natural block having a variety of sand, there was ability to purify pollutants by microorganism and filtration. There was ability to purify pollutants in natural section of the natural midstream which have a diversity and a plenty of sands. In Tongbok upstream BOD concentration was lower than that of reservoir, but in midstream which was straightened concrete block without sand, BOD and NH$_3$-N concentration was higher than that of upstream and deteriorated water quality.
