In this paper, formulas to esthnate the siltation mainly due to suspended sediment in the harbour basins and dredged navigation channels are derived. Siltation amount and its thickness computed by this method togather with two-dimenslonal computation model in the Xinsha Harbour Area of Huangpu in Zhujiang River Estuary are well close to those obtained by the physical model test. As the construction of the new harbour area causes the constraction of river width, flow velocity either in flood or in ebb will then be increased and the siltation amouut in the harbour basin and the navigable channels would also be decreased.

本文导出以悬沙淤积为主的河口航道开挖后回淤量的计算式,分析了珠江河口黄埔新沙港区的实测资料以及已有航道浚深后的回淤变化和经验;使用二维潮流数值模型得出的流速值,预报新沙港区在开挖港池和航道后的淤积数量。预报表明,与物理模型常规试验的结果相接近,而物理模型试验中曾延长上游洪峰(即加大流量)所得出的淤积量偏大。珠江是多水少沙河流,建新沙港后河道缩窄,涨、落潮流速有所增加,也可以减少泥沙的回淤量。
