| Abstract |
The purpose of this study is to evaluate on the applicability of the Load Duration Curve (LDC) method using a Maintenance of Variance Extension type 2 method and sampling data for efficient total maximum daily loads at the Nakbon-A unit watershed in Korea. The LDC method allows for characterizing water quality data, such as BOD, TOC, T-N and T-P in this study at different flow regimes (or quarters). BOD usually exceeded the standard value (probability 50%) at the low flow zone. On the other hand, TOC, T-N, and T-P usually exceeded the standard value at the dry and low flow zone. Seasonally, all water-quality variables usually exceeded the standard value at Q1 (Jan-Mar) and Q2 (Apr-Jun) zones. Improvement of effluent control from wastewater-treatment plants are effectively improves BOD and T-P. |
