Academic Editors: Rao Bhamidiammarri and Kiran Tota-Maharaj Received: 27 December 2015; Accepted: 31 March 2016; Published: 8 April 2016 Abstract: In this study, the Mudan River, which is the most typical river in the northern cold region of China was selected as the research object; Environmental Fluid Dynamics Code (EFDC) was adopted to construct a new two-dimensional water quality model for the urban sections of the Mudan River, and concentrations of CODCr and NH3N during ice-covered and open-water periods were simulated and analyzed.
