Focusing on such several key issues of flood utilization as resources in a basin as potentiality of flood resources in a basin, seasonal variation principle of storm flood in a basin, stage quantitative description method during flood period, computational method of stage design flood and risk design of adjustment and application of limited level of reservoir during flood season, deepgoing study is conducted in this dissertation.

论文围绕流域洪水资源利用的若干核心问题：流域洪水资源化潜力、流域暴雨洪水的季节性变化规律、水库汛期分期定量描述方法、水库分期设计洪水计算方法以及水库汛限水位调整运用的风险设计等进行了深入研究，构建了利用水库汛限水位调蓄洪水资源的理论体系和技术框架。

From the analysis of the historical and measured data, some tendencies of flood in Zhejiang in the global change are predicted: 1low water year will take the upper hand in ten years or more, the global change will make the temporal and spatial changes of flood in Zhejiang more violent, and the flood disasters in coast area more serious.

中文摘要：根据历史和实测资料分析，对于全球变化下浙江近期洪水的运作大势，可得如下几点认识：（1）在未来的十几年之内，浙江省将处在枯水年占优势的阶段，但全球变化将使浙江洪水的时空变化更为剧烈，使沿海地区的洪水灾害更为严重。

To use the flood resources adequately and fully,the method which considers the time series variance law of flood statistical characteristics within the year to calculate staged limited water level in flood season and design flood is proposed.Case study demonstrates that the method is feasible and appliable.

为更好地提高洪水资源利用率，基于暴雨洪水的物理成因和统计规律分析，提出采用年内洪水统计特性变化规律来确定设计洪水和各分期汛限水位的新方法，结合实例说明该方法在汛限水位动态控制中的实用性和可行性。

According to the flood data of Urumqi River from Yingxiongqiao hydrometric station over the past 49 years,the spatiotemporal change characteristics of the Urumqi River flood are briefly analyzed with various methods.

主要依据英雄桥水文站实测洪水资料对乌鲁木齐河洪水时空变化特性进行简略分析，通过多种方法分析了乌鲁木齐河49a来洪水的变化趋势。

There are two kinds of flood: rain gush flood and ice flood.

黄河流域面临两类洪水的威胁，即暴雨洪水和冰凌洪水。

On the basis of genetic analysis and flood time,the flood in Heilongjiang was divided into three types,that is ,storm flood, snowmelt and rain flood and ice flood in this paper.

按成因和发生时间，将黑龙江省的洪水划分为三种类型：暴雨洪水、融雪和雨雪融合洪水、冰凌洪水；着重论述了暴雨、洪水的时空分布特征以及暴雨洪水的稀遇程度等。

But floods occur in many other ways, heavy rains and thawing snowfall can overwhelm rivers, storm surges caused by hurricanes and tsunamis inundate the coastline, landslides and mudflows can displace large volumes of water.

但是，洪水的暴发也有其它的情况，暴雨和积雪熔化可导致河水泛滥，暴风雨和海啸引发的洪水会淹没海岸，并引发泥石流和滑波，从而分流了大量洪水。

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。
