| 摘 要： | 对于天然复式河槽,当糙率随着断面湿周变化发生明显变化,且模型过程水位变化较大时,采用一般综合糙率,将会造成较大的误差.本文采用EBM综合糙率法对东江三角洲"2005.6"洪水过程进行模拟,并与一般综合糙率法计算结果进行对比分析,结果表明,EBM综合糙率法模拟的效果更精确.

| Abstract: | With regard to natural compound river channel, on the condition that the roughness varies evidently along with the variation of cross section wetted perimeter and the variation of the process water level is larger, the adoption of comprehensive roughness will produce larger error. The paper simulates "2005.6"flood process in Dongjiang delta with EBM comprehensive roughness method, compares it and the result calculated by ordinary comprehensive roughness method. The result indicates that the simulation effect of EBM comprehensive roughness method is exacter. |
