The Study and Applications of One-dimensional Unsteady Water Quality Model for the Lower Yellow River

摘要：

An one-dimensional hydrodynamic numerical model was established for the lower reaches of the Yellow River and coupled one-dimensional water quality model, then the finite volume method was used for the basic equation discretization. The discrete equation was solved by using the forecast-revision of second order in time. This method features good conservation, simple operation, universal application and better practicability in forecasting normal flood and the flood wave evolution of dam-break. At the same time, the sudden pollution accident can be initially simulated in the lower reaches of the Yellow River.
