In order to calibrate the model, data of six typhoons such as the flood peak and the peak time are collected to compare with the result of the simulations. The result shows that the difference of the inflow hydrograph between them is very close. The average error of the flood peak is 5.21%. Furthermore, the error of the peak time is less than one hour but Wenny Typhoon is an exception by more than two hours. Therefore, the model could be applied to simulate the rainfall event at Shih-men watershed.

为验设模式模拟精确性,本研究以具代表性之六场台风降雨模拟,针对石门水库入流历线之观测流量与模拟值比较,结果显示模拟之水库入流历线与观测值差异不大,其尖峰流量误差绝对个平均为5.21%;另在预测洪峰到达时间方面,除温妮台风迟迟2小时外,其余均在1小时内,显示本分析模式可应用於石门水库上游集水区暴雨事件模拟。

It would reduce peak floods by 20% to 25%, benefitting both counties, and augment lean season flows by 30% to 40%, so in the summer there would be more water.

该计划会将洪峰减量20%至25%,对两个国家都有利,而且能在旱季时将流量增大30%至40%,因此在夏季的时候就有更多水可供利用。

Yu started a how smuggling is not willing to admit to the fact that he has done a variety of explanations. description of the true price and the price gap between the declaration of technical services, Yu is a certain eloquence, But the water from his or words to identify the loopholes, rebutting each, the trial of 10 days, a thin metaphor. Finally he smiled :"I do this series, or an account of it."

开始喻某怎么也不愿承认走私的事实,他做了多种解释,说明真实价格和报关价格的差距是技术服务费,喻某很善辩,但是洪峰还是从他的话里找出了漏洞,一一反驳,审讯了10天后,喻某词穷了,最后他自己都笑了:&我编不下去了,还是交代了吧。&

By theory analyzing and example calculation and comparison, the conclusion is obtained that the traditional inferential method can be applied in the design flood peak flow calculation, yet it cannot truly express the runoff process of the rain drainage inlet, the instantaneous unit hydrograph depending on the real and actual datum is different to be used in the runoff discharge hydrograph calculation, and the no linearity reservoir means and the isochronal method have some physics base and its parameters easily evaluated and its runoff discharge hydrograph still more is close to practice.

5通过城市雨水地表汇流特性及计算方法的理论分析、实例计算和对比得出:传统推理法可应用于城市设计洪峰流量的计算,但不能真实地反映雨水口径流流量过程;瞬时单位线法等对实测资料有较大依赖,难以应用于城市径流流量过程线的计算;非线性水库法和等流时线法的径流流量过程线接近实际。

The design flood of Eco-industrial Parks in Handan is studied in the paper.According to characteristics of hydrology and geography in the area of Eco-industrial Parks,the basin is divided into four subareas and the design floods in different subzones are calculated using precipitation and runoff data.

根据工程所在流域实际地理、水文等特点,将流域分为4个分区,利用降雨和流量资料推求出工程所在区域不同分区的设计洪水,而后利用马斯京根法和流量过程叠加原理得到目标断面设计洪峰流量1 132 m3/s,该结果与历史洪水和以往设计成果进行对比验证,确定计算结果合理可靠,符合未来洪水变化情势。

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.
