Case Study: Numerical Modeling of the Tidal Bore on the Qiantang River, China

The tidal bore at the estuary of the Qiantang River in China is one of the most spectacular bores in the world. Although it is a famous scenic spot, it may cause disasters due to its destructive power. In this paper, a new numerical model, based on a Godunov-type scheme with the water level-bottom topography formulation combined with the improved wet/dry techniques, is constructed to numeri- cally simulate the tidal bore on the Qiantang River. The simulated results using the model agree well with observed data, which shows that the model can reproduce the formation, evolution, and dissipation of the tidal bore on the Qiantang River.
