【Abstract】 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. \;更多还原
