| 1. | Research on yellow - river - crossing works and river regime flood control 南水北调中线穿黄工程河势与防洪初步研究 |
| 2. | River regime evolution at tongling reach of the yangtze river and the influence of 1998 embankment works on river regime 长江铜陵段河势演变及隐蔽工程对河势影响 |
| 3. | The effect of lateral boundary condition , the river regime and the bed material on lateral erosion are analyzed 结果表明:水库下游均会有河岸侵蚀发生,但初期一般以下切为主,后期以展宽为主。 |
| 4. | Research on river regime and flood control at the site of the yellow river passing - through work of the middle route project of south - to - north water transfer 南水北调中线穿黄工程对河势与防洪影响的试验研究 |
| 5. | To stabilize the river regime , the phase i and phase ii regulation works have been implemented for years on this reach , resulting in the substantial control of severe change of regime 多年来为稳定河势,镇扬河段已实施了一、二期整治工程,使剧烈变化的河势已基本得到控制。 |
| 6. | It is concluded that the phenomena of replacement of spatial and temporal process is typical in the erosion development , the coarsen of riverbeds , the sediment concentration and the change of river regime , etc 分析表明,河流再造床过程在冲刷延展、河床粗化、含沙量及其特征、岸滩侵蚀以及河型变化等方面具有较典型的时空演替现象。 |
| 7. | According to the practice of waterway regulation in the mid & lower streams of hanjiang river during the past 50 years , this paper puts forward 33 suggestions on key points of waterway regulation design such as river regime control , bed evolution analysis , etc 摘要根据半个世纪以来汉江中下游航道整治工程情况,对整治工程设计中的关键性问题,提出了控制河势、重视和利用节点等33条建议。 |
| 8. | To prevent unfavorable impact of sand mining on river regime stability , flood control safety , navigation safety , water ecological environment protection and normal operation of industrial and agricultural facilities along the river , the sand mining in the yangtze river must be planned unitarily 为防止采砂对长江河势稳定、防洪安全、通航安全、水生态环境保护以及沿江工农业设施的正常运行带来较大的不利影响,长江河道采砂必须进行统一规划。 |
| 9. | ( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches . ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches . simultaneously , the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load , the regional crustal stability , the evolvement of river regime and the stability of river dikes , can reflect the actual situation of hang river in the lower yellow river more fully 评价结果同时表明,从水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面建立评价指标体系,能够更加全面的反映黄河下游悬河的实际情况;运用多层次模糊综合评判法能够较好地解决影响因素众多、作用机制复杂的悬河决溢风险问题;运用gis技术强大的空间分析功能,使黄河下游悬河不同空间位置的决溢风险得到了量化,可以客观地反映黄河下游河道不同空间位置决溢风险的差别,对于指导防洪和河道治理的实践具有重要的现实意义。 |
| 10. | Based on the river regime of tgp dam area and the arrangement of upper and lower access channels , the experimental research on the influence of such unsteady flow on the navigation , the evaluation of navigable conditions under the unsteady flow and the study of corresponding improvement measures are presented in this paper 本文结合坝区河势特点及上下游引航道布置,试验研究了大坝泄洪及船闸充泄水非恒定流对上、下引航道通航影响,同时进行了非恒定流通航条件评价及改善措施研究。 |
