一小清河是山东省省会一济南市的入海水道,河口拦门浅滩是其航行障碍。在研究小清河口外航道整治措施时,必须分析黄河入海泥沙对小清河的影响,因为现在黄河河口距小清河口仅55公里,黄河是一条每年有12亿吨泥沙入海的巨沙河流,这些泥沙除大部分在河口外三角洲地区沉积外,被海洋动力挟带至较远海区的泥沙约4—5亿吨/年。如果这部分泥 A Xiaoqing River is the capital of Shandong Province, Jinan City into the sea, shoals estuary shoal is its navigation obstacles. When studying the remediation measures of the outer channel of the Xiao-Qing River Estuary, it is necessary to analyze the influence of the sediment from the Yellow River to the Xiaoqing River. Because the Yellow River mouth is only 55 km away from the Xiaoqing River estuary, the Yellow River is a giant Shahe River with 1.2 billion tons of sediment entering the sea each year. Apart from the sediments mostly deposited in the estuarine delta, silt is carried by marine power to about 400 million tons of sediment in the more remote areas. If this part of the mud
