| 中文摘要: |
| 利用赣江尾闾河网模型，通过封堵北支、整治南支等工程措施，研究河道整治工程条件下赣江尾闾河道水位变化特性，探讨整治工程对赣江尾闾防洪影响.模型试验结果表明：封堵北支后，赣江尾闾各支流水位都有所抬高，并且流量越大水位壅高越高，水位壅高对赣江洪水期防洪产生较不利影响；南支整治使得南支过流能力加大，赣江尾闾洪水期大多数河段的水位降低，对赣江尾闾河段洪水期防洪有利，但降低的幅度在0.1m以内，由此产生的影响范围和效果有限. |

| In order to study flood control problem in the tail of Ganjiang river，water level was studied based on Ganjiang River network model under changing conditions which were caused by engineering measures，such as plugging measures、regulation measures.The results showed that：when the north branch was plugged，water levels in branches were risied which lead a negative effect on flood control.When regulation measures were implemented，conveyance capacity of south branch was improved，water levels in most reaches falled during the flood period，which lead a positive effert on flood control.But the reduction is within 0.1 meters，the effect caused by that were limited. |
