Unsteady Water Quality Model for River Network
A complex river network system consisting of branches and loops is sometimes complicated by downstream effects from tides, lakes, and other factors. The management of water quality in such rivers is a difficult task. A model was developed to simulate hydraulic behavior and water quality of a river network on a one-dimensional representation. The two complete St. Venant equations and the transport equation were solved by a finite difference implicit method using a modified Gauss elimination procedure. The model can simulate biochemical oxygen demand, dissolved oxygen, and any conservative substance. The hydraulic module of the model was adjusted and verified with data from the Jacui Delta, Brazil, showing good agreement between the calculated results and the observed data. The water quality model was tested under hypothetical conditions for the same Delta to demonstrate the utility of the model in making managerial decisions.
