초록
This study is performed to increase the accuracy of the water quality modeling. Two water quality models such as QUAL2E and QUAL2K (or Q2K) are applied to simulate the water quality of Gokgyochun. The simulation results of both QUAL2E and Q2K show generally similar ranges of error although the differences of internal reaction mechanism of both models cause insignificant disagreement. In the Q2K model, BOD variable can be divided CBOD (cs) and CBOD (cf), that is, CBOD (cs) is increased by degradation of detritus and fast reacting CBOD (cf) is increased by hydrolysis of CBOD (cs). In addition, a decrease in concentration of CBOD caused by denitrification is considered in Q2K differently in QUAL2E. For the calculation of nitrogen concentration,QUAL2E simulates four different types of nitrogens such as ammonia, nitrite, nitrate, and organic nitrogen, but Q2K three different types of nitrogens except nitrite. Also, Q2K model include attached bottom algae for the simulation of phosphorus concentration. These differences of reaction mechanism between two models represent different simulation results. In conclusion, it is advisable to use more than two models simultaneously for the stream water quality modeling and Q2K model is recommendable to apply after due consideration of extensive reaction mechanisms and user-friendly model interface.
Abstract
This study is performed to increase the accuracy of the water quality modeling. Two water quality models such as QUAL2E and QUAL2K (or Q2K) are applied to simulate the water quality of Gokgyochun.

In the Q2K model, BOD variable can be divided CBOD (cs) and CBOD (cf), that is, CBOD (cs) is increased by degradation of detritus and fast reacting CBOD (cf) is increased by hydrolysis of CBOD (cs).
