摘要
基于典型潮滩剖面高程重复测量及沉积物取样数据,分析了某丁字湾沿岸潮滩短期演化特征和沉积物运移趋势。结果表明,在1个月的时间内,该区潮滩整体处于稳定状态,局部略有弱冲淤现象。GSTA模型分析结果表明,该区潮滩沉积物以缓慢向海搬运为主,局部泥砂有往复运动和淤积现象,长期潮滩表现为弱侵蚀状态。
The paper makes a study on the intertidal zone evolution and the sediment transportation at a t-shaped bay based on the repeated surveying,in a month,on the typical tidal flat profile and sediment sampling data.The results show that the whole tidal flat is in a stable state;while weak erosion and deposition are found at local areas.GSTA model analysis results show that sediments are transported slowly to the sea,but remain reciprocating sediment movements and siltation are found at local areas.In a long-term,the intertidal zone is in a weak erosion state.
