钱塘江河口围垦对台风暴潮影响的数值模拟

应用一、二维耦合的数学模型对钱塘江河口大规模围垦前后台风暴潮水位进行数值模拟,结果表明缩窄后遭遇类似9711台风及特大台风暴潮时,沿程暴潮水位均不同程度地抬升,一般盐官的抬升最大,由盐官往上游或下游递减.

Numerical simulation of effects on storm-induced water level after contraction in Qiantang estuary

The shallow water wave equations coupled with 1|D and 2|D are used to simulate the storm|induced water level before and after river contraction in Qiantang estuary. The computed results show that after contraction, the storm|induced water level along the river increases in different degree if encounters with 9711# typhoon or especially another strong typhoon, at Yangan, it reaches the most, and it decreases upward or in lower reaches. ;
