It proposed to establish perfect ecosystem function conservation monitoring system, to conduct some ecosystem rehabilitant and build up engineering project, and achievement; to solidify the results of return polder back to lake, and setup immigration residents. And to improve the flood regulation function capacity; Wetland and the biodiversity can be protected effectively; Basically to curtail degradation of ecosystem function, and ecological environment, people's living condition and quality will be improved greatly.

Long—term objective ：建立完善的生态功能保护区监管体系；实施一批生态恢复和环境治理工程，并取得一定效果；退田还湖、平垸行洪和移民建镇的洪水治理成果得到切实巩固，调蓄洪水的生态服务功能得到加强；湿地及其生物多样性得到有效保护；基本扭转洞庭湖区生态环境退化的趋势，湖区生态环境得到明显地改善，人民群众的生活水平和生活质量有所提高。

The author analyzed the reasons of damage caused by "03·8"flood occurred in Weihe River from the general situation of the lower reaches of the river, the feature of the flood and the flaws of the dike, in hoping to give the reference for riverway engineering of the lower reaches of the Weihe River in the future.

从渭河下游的概况、"03·8"洪水的特点和渭河堤防工程的不足等方面对渭河"03·8"洪水造成的灾害原因进行初步探讨，以期对今后渭河下游的河道治理工程提供参考。

As the country's four major river flood control, one of the Yongding River is the city's main flood discharges from the river, the main flows through the Shijingshan District, Fengtai District, and Mentougou.

作为国家的四个主要河流洪水控制，其中永定河是城市的主要排放洪水的河流，主要流经石景山区，丰台区和门头沟区。

Based on field investigation and historical data analyzing, the characteristics and causes of flood disasters of Qinba Mountain area were discussed in this paper. Take the harnessed Watershed and unharnessed Watershed as comparative study objects, through analzing the two typical watershed land using and rainfall-runoff dynamic data, combinating the in-situ soil infiltration field testing, a rainfall-runoff model of small watershed which was appropriate to Qinba Mountain areas was built based on improving the SCS model. And then the influence of soil and water conservation measures on the flood processes was analysed.

本文通过野外调查与历史调查资料，阐述了秦巴山地区洪水灾害的特点及成因，以治理流域与未治理流域为对比研究对象，通过对两条典型流域的土地利用状况分析，结合土壤入渗原位测试，充分利用降雨、径流动态观测资料，以SCS模型模拟降雨径流为重点，建立适合于秦巴山地区小流域的降雨径流计算模型，分析水土保持措施对于洪水的作用过程。

Falling into a sleeplike condition, he suddenly felt as though he were sinking in a mighty flood of water, and the rush and roar soon took musical shape within his brain.

他进入了似睡非睡的朦胧状态，骤然间感觉到自己仿佛掉进了滔滔洪水之中，不断在下沉，很快，洪水的冲击声和咆哮声以音乐的形式呈现在他的脑海里。

The study result indicates that flood usually oc curred in the climate transition period. Based on the result, the author believe s that the appearance of flood may be in a certain relation with the abrupt clim ate event in the process of the global climate evolution.

同时在研究中还发现，古洪水多发生在气候转型期，因此笔者提出古洪水的发生可能与全球气候变迁历史中的突变事件有某种必然的联系。

In fact, the tributary acts as a conditioning reservoir, which is an important factor to sudden flood caused by dam collapse.

在处理洪水演进过程中支流与干流洪水的相互影响时，以前的模型仅将支流流量迭加到干流同时刻的流量上。

Within a single storm, process of runoff and sediment seem the same in outsets of different scale watersheds, about runoff rate is 1.27 m/s, concentration of sediment tend to change little and nearly 700 kg/m~3, this determine the relationship between water and sediment, or the relation reflect study area situation, for example, soil and event storm and sediment and so on. In fact this program established scale transition partly.(2)The loess plateau in north china is located in the middle yellow river basin, and records some of the highest erosion rates in the world. The hilly part of the loess plateau is one of the most severely eroded regions of the loess plateau.

基于此本论文选择陕北大理河流域为对象，依据黄河支流的水文资料，分析了不同尺度大小流域的水沙侵蚀资料，取得以下结果：(1)发现就次暴雨洪水而言，各尺度流域出口的径流泥沙过程都表现为洪峰陡涨陡落沙蜂陡涨缓落，含沙量随流量增大到一定程度1.27m／s时变化趋于稳定，保持在400kg／m~3以上，决定了该地区水沙之间的关系，不同尺度大小流域出口暴雨洪水的水沙关系在一定程度上是一个区域特征值。

It is safe and precise for configuring pressure chamber and inlet well.Based on the tests and theory calculations, the paper demonstrated that computing tilting moment and resisting moment could attain self-tilting weirs tilt behavior.

自溃式迷宫堰具有超泄能力强且可倾覆的特点，通过调整进水井顶部高程和底板配重控制倾覆时机，具有非常高的安全度和精确度，能满足常遇洪水和超标准洪水的防洪要求。

Massive floods that struck the southern Mexican states of Tabasco and Chiapas in late October and November left vast stretches of land completely submerged — an estimated 80% of Tabasco was under water at one point, and as many as one million residents were affected by the floods.

今年10月底和11月，汹涌的洪水侵袭了墨西哥南部的塔巴斯哥和恰帕斯，致使陆地变成了水世界，大概塔巴斯哥有80%土地被水淹没，近100万居民的生活受到了洪水的影响。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
