长江石首河段航道整治工程行洪影响研究

分析了长江石首河段航道整治一期工程河段近期河床演变特点及演变趋势，采用平面二维水流数学模型计算分析了工程对河道水位及流场等的影响，并综合分析了工程对河势和行洪的影响。研究结果表明：拟建工程实施后不会对该河段行洪及河势产生明显的不利影响，但局部河势仍会有一定的调整。该研究成果可为航道整治工程设计提供科学依据。

Study on influence of channel regulation project on flood discharge in Shishou Reach of Yangtze River

We studied the recent feature and tendency of the fluvial process after implementation of the proposed phase-I works of channel regulation project in Shishou Reach of Yangtze River.Integrating 2D mathematical model,the influence of the project on water level,flow field,river regime and flood discharging is analyzed comprehensively.The results show that the implemented works will not cause adverse effect on flood discharging and river regime,but local river regime will be adjusted,which can provide a scienti...
