Abstract
Non-point pollution source is difficult to control due to uncertain outflow path and emission. So, There are many development and research to Best Management Practices(BMP) established to manage the Non-point pollution source. Besides, various methods of estimated efficiency to exact assessment of BMP is presented. In this study, the impact about length of Grassed Swale on reduction efficiency based on monitoring results of Grassed Swale by length is studied. By estimating Grassed Swale reduction efficiency in a variety of methods, the difference between the methods of estimated efficiency was compared with those that. Estimated efficiency method using ER, SOL, ROL, ROF, SOLF, and ROLF methods is analyzed. EMC analysis result is high inflow and outflow concentration distinction organic compound for nutritive salts The result of efficiency analysis along Grassed Swale length sharply increases in a Grassed Swale inlet. After this increase, the efficiency gradually decreases. This is expected that cistern installed in the end of the front. To obtain a stable reduction efficiency of Grassed Swale, minimum length 30m of Grassed Swale should be enough. Also, in order to efficiently and economically design Grassed Swale, the researches on length of Grassed Swale are needed rather than simple analysis of efficiency.
