Firstly, the flood control regulation of TGP in Sep is computed based on the analyses on the inflow in Sep and Oct, and the risk and loss on the ahead impounding scheme is calculated and analyzed. Then, the storage level, power production and releasing discharge are achieved by computing on the electricity generation model through reservoir regulation graph. Thirdly, obstruction in channel is analyzed and the problem in the Chongqing reach is more serious in 175-145-155m scheme. The sediment aggrading process and distribution on different schemes is calculated by 1-D reservoir mathematical model. The navigation benefit is computed by navigation model. Based on above calculations, the impounding time is decided by the multi-purpose decision model, and evaluate by analytical hierarchy and balance layout model. A best impounding scheme is achieved to match the requirement of flood control electricity generation and navigation et al.

首先，在对宜昌站9、10月份来水分析的基础上，采用第2章建立的防洪优化调度子模型进行了三峡水库9月份防洪调度，分析了汛末提前不同天蓄水对防洪的影响，计算了汛末不同蓄水方案水库9月份的洪灾风险率和风险损失；接着，根据第2章建立的发电调度子模型进行了三峡水库发电调度计算，得出了不同蓄水方案下水库的坝前水位、发电量及下泄流量过程；然后，分析了175-145-155m方案下三峡水库的碍航问题，指出175-145-155m方案下重庆河段的碍航问题最为严重，通过进行不同蓄水方案下水库一维泥沙冲淤计算，得出了不同蓄水方案下库区淤积过程及分布，并通过航运调度子模型，计算了不同蓄水方案下水库的航运效益；最后，根据以上防洪、发电及航运调度计算的结果，运用第3章水沙多目标决策模型对水库的蓄水时间进行了多目标决策，并采用层次加权均衡规划模型对计算结果进行评价，得到一个能满足水库防洪、发电及航运各方面要求的最佳蓄水方案。

Aimed at the complexity of fluvial strata, such measures as well cyclical comparison, step control and geological analysis of reference beds have been applied. Moreover the paper has developed a set of methods the techniques to extract the parameters controlling the formation of intra-sandbody thin interbeds. The present study has examined how thin interbeds affect the frame property and heterogeneity of individual sandbodies; revealed the permeability space distribution mode of meandering distributary channel's single side lithosomic body and straight distributary channel's aggrading lithosomic body. Through applying the distributary channel sandbody structural unit classifying and identifying method achievement, some horizontal wells have been deployed to dig the residual oil in the top of hick pay zone in the xing8-9 area, which shows better effect after they have been put into production.

针对分流河流砂体沉积特点采用了旋回对比、分级控制、不同相带区别对待的单油层对比方法；利用取心井、对子井等资料研究形成了分流河道砂体内部结构单元的倾角、倾向、规模等参数的提取方法；搞清了内部结构单元对单一砂体内非均质性的控制作用，建立了分流平原相单一点坝侧积体及顺直型分流河道单一加积体层内渗透率分布模式及剩余油分布模式，应用分流河道砂体结构单元划分方法识别研究成果，在杏树岗油田杏八九区纯油区部署了水平井，投产后见到了较好的厚油层顶部剩余油挖潜效果。

In case of a dam break, the quick and efficient alerting of the population is crucial to their safety.

发生溃坝时，及时有效地组织报警和发布信号也是保障人民生命安全的一项重要措施。

It only took 38 months from construction preparation at the end of October, 2001 to the first unit operating on December 20, 2004, which antedated the construction time limit by 7 months. During the period, 5-month-construction period delayed was saved because of the karst geological problems of dam's partial foundation. 3 units were put into operation in 2005, especially it only took 23 days from the runner of 4# unit hoisted to put into operation. It created the wonder of installing large axial-flow feathering unit.

乐滩电站从2001年10月底开始施工准备到2004年12月20日首台机组投产发电，仅用38个月的时间，比合理工期提前了7个月，并在此期间，抢回因厂坝部份地基岩溶地质问题延误的5个月工期。2005年又实现了年内3台机组投产发电，尤其4号机组从转轮吊装到机组并网发电，仅用23天，创造了大型轴流转桨机组安装奇迹。

It seems likely that changes in snowfall amounts, with season or in storm intensities, will alter the timing, temperature relations, and extent of avalanching.

小胡姆丹冰川在19世纪也形成过大型冰坝，其边缘已经进入河流并且从河上横跨过去，现在河水是从冰下流过的。

The first is tidal barrages where the technology is similar to that used in hydropower stations.

第一种方法是潮汐堰坝，这种科技与水力发电厂十分类似。

The main target zone of the CARACOLES area in eastern Venezuela basin is a series of delta facies sedimentation in ocean-land transitional environment.

东委内瑞拉盆地卡拉高莱斯地区主要目的层为一套海陆过渡环境的三角洲相沉积，三角洲平原河道、三角洲前缘水下分流河道、河口坝及决口扇构成区内主要沉积骨架砂体，各种微相砂体单层厚度薄，分布面积小，在地震剖面上无法直接识别。

It also remains unclear whether the software can be turned off, or circumvented.

目前也不清楚用户能否关闭或是绕过&绿坝&软件。

They have dammed up the valley and built a reservoir.

他们已经在山谷里筑了坝，建造了水库。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
