【摘要】 钱塘江河口是典型的喇叭形河口,其强潮动力与易于悬浮冲刷的河床底质使其河口具有淤积下移趋势,但天然状态下河口下移过程是长期的,而河口整治则强化了这一趋势,加速河口的淤积下移。更多还原

【Abstract】 Qiantang Estuary is a typical funnel-shaped estuary. Its strong tidal power and easily suspended and eroded riverbed result in a trend of siltation and downward movement,while naturally this should be a long term progress. Estuary regulation enhanced this trend,and accelerated the siltation and downward movement of the Qiantang Estuary.更多还原
