摘要(Abstract):
采用三维数学模型研究黄河口泥沙输运过程,并利用实测资料对模型进行了检验。数值模拟结果揭示了黄河口切变锋的时空运动过程及其对河口泥沙传输的作用。黄河口切变锋在涨、落潮时段存在两种不同的形态,分别历时2小时左右。切变锋在浅水区域产生,向深水区移动,经历2小时左右消失,它的产生是由于近岸区域与10 m深线以外区域的潮汐相位差所导致。切变锋对河口泥沙的向海传输有重要的阻隔作用,导致河口泥沙集中在切变锋的向岸一侧随落潮流向北侧传输,在涨潮时河口向海排沙量降低,少量泥沙随涨潮流沿岸向南传输。长期的地貌演化表明切变锋对河口的淤积和侵蚀分区有重要的控制作用,导致河口泥沙在其向岸一侧沉积,是长时间尺度的河口地貌演化对短时间尺度河口沉积动力过程的重要响应。
