摘　　要：本文利用实测资料，分析了清水沟流路自1976年改道以来的水沙特点、演变规律以及河口淤积延伸的特点。1996年清8人工出汊工程实施后，在减轻河口地区防洪压力和淤海造陆变海上石油开采为陆上开采方面取得了很好的效益。同时对入海流路规划改走北汉的海域条件和改走北汊的行水年限进行了分析和详细计算。通过分析认为：只要辅以必要的治理措施，清水沟流路还有一定的行河潜力，预计改走北汉后，可行水15年左右。The charateristics, evolution law of inflow and sediment of Qingshuigou since its flow path changed in 1976,and extension features owing silt of the Yellow River mouth are analyed in the paper on the basis of field date. Since Qing No. 8 artificially braided channel project carried out in 1996,perfect effects have achieved in the aspects of alleviating the pressure of flood protection in the Yellow River mouth area and changing petroleum recovering from sea into on land through sediment silt in the sea to make land. At the same time,ocean conditions for the planning of changing the flow path to north braided branch to the sea and flowing duration limit of the north braided branch have been analyzed and calculated in detail. It is conyidered through analysis that Qingshuigou flow path will be of some capabilities for flbong through only if there are necessary administration measures, and if it is changed to the north braided branch the estimated duration is areund l5 years.
