| Abstract |
| This study monitored the water qualities of 16 streams, which flow to Masan bay during 2005-2013. The characteristics and probability distribution of the water qualities were analyzed. The water quality, BOD, of 8 streams were found to have a log-normal probability distribution. The characteristics of probability distribution of stream water qualities could be used for determining the target concentration of stream water qualities. Determination and setting of the target concentration of stream water qualities using the probability distribution could improve the total pollution load management system (TPLMS) currently being regulated in Masan Bay watershed, Korea. Reliability analysis method was applied to fine the coefficients of reliability (COR), in terms of the compliance of the target water qualities. The target management concentrations to meet the target stream water qualities were calculated from the COR obtained. This study discusses the importance of interpreting monitoring results of water qualities distribution for setting up the target water quality of the streams and compliance with legislation. |
