中文摘要：

应用有限体积法离散一维圣维南方程，对界面通量采用迎风格式求解，对水面坡降项采用迎风和顺风的加权平均计算。模型模拟了溃坝波、亚临界流等典型算例，并经实测涌潮资料验证，较好地模拟了钱塘江涌潮形成、发展和衰减的全过程。分析涌潮计算成果，加深了对钱塘江涌潮的认识。

英文摘要：

1D Saint Venant equations are solved using finite volume method, the interface flux is computed by upwind method, and the water surface gradient is evaluated by the weighted average of both upwind and downwind gradients. The model was tested with typical examples, including dam-break flow and transcritical flows. Then the model was applied to simulate the entire process of the formation, evolution and dissipation of the tidal bore in the Qiantang River. A good agreement was seen between the computation and field measurements. A deeper understanding of the tidal bore in the Qiantang River was achieved through the analysis of the computational results on the tidal bore
