AB - In this study, we analyzed probability distribution of EMCs (Event Mean Concentration)of COD, TOC, T-N, T-P and SS from rice paddy fields and compared the mean values of observedEMCs and the median values of estimated EMCs (EMC50) through probability distribution. The fieldmonitoring was conducted during a period of four crop-years (from May 1, 2008, to September 30.
2011) in a rice cultivation area located in Emda-myun, Hampyeong gun, Jeollanam-do, Korea. Fourprobability distributions such as Normal, Log-normal, Gamma, and Weibull distribution were usedto fit values of EMCs from rice paddy fields. Our results showed that the applicable probabilitydistributions were Normal, Log-normal, and Gamma distribution for COD, and Normal, Log-Normal, Gamma and Weibull distribution for T-N, and Log-normal, Gamma and Weibulldistribution for T-P and TOC, and Log-normal and Gamma distribution for SS. Log-normal and Gamma distributions were acceptable for EMCs of all water quality constituents(COD, TOC, T-N,T-P and SS). Meanwhile, mean value of observed COD was similar to median value estimated bythe gamma distribution, and TOC, T-N, T-P, and SS were similar to median value estimated by lognormaldistribution, respectively.
