In the Qual2E stream water quality simulation model, the hydraulic coefficients are assigned to the reach that is collection of computational element. This study developed a module that can incorporate the results of nonuniform flow analysis to specify such hydraulic characteristics for each individual element. Flow variation depends on many factors such as cross sections, channel slopes, and bed materials. Detailed flow analysis is essential to increase the accuracy of water quality simulation. The model has been applied for certain reach of the Han River where significant flow change is expected due to submerged weir. From the result of water quality simulation, the developed module contributes to describe the effect of submerged weir without considering reaeration coefficient. |
