【摘要】 根据原型实测水文资料和实体模型实测资料,对影响长江重庆九龙坡河段泥沙淤积的主要因素进行分析,得出了泥沙淤积量与年输沙量、年径流量、泥沙粒径和嘉陵江入汇汇流比之间的定量关系。在此基础上建立了综合反映各因素定量关系的计算公式。更多还原

【Abstract】 Based on field measured data and physical model test data,the authors analyze the main factors affecting the sedimentation in Chongqing Jiulongpo reach of the Yangtze River.The quantitative relation between the sedimentation amount and annual sediment load,annual runoff,sediment size and the inflow rate from Jialing River is obtained.Finally,the expression to calculate the sedimentation in Jiulongpo reach is given.更多还原
