| 1. | A flood peak cut coefficient ( ) is proposed to measure the affection of the flood hydrograph for the risk calculating of the flood discharge 本文分析了洪水过程这一不确定性因素,并用洪峰削减系数将洪水过程的不确定性量化。 |
| 2. | In this paper , those uncertain factors affecting the flood discharge are discussed , especially the uncertainty of flood hydrograph 本文全面考虑了影响施工导流及泄洪风险的不确定性因素,重点分析了洪水过程的不确定性对施工导流及泄洪风险的影响。 |
| 3. | So the uncertainty of flood hydrograph is really a important factor which contributes to the risk of flood discharge . for practical usage , c programs are written for dealing with so much data 针对调洪演算重复、繁琐、工作量大的特点,本文也编制了处理前期数据的计算程序。 |
| 4. | Project i , project ii and project iii that are different in processing precipitation data as the input of hydrological model were built to model day hydrograph and flood hydrograph , so as to analyze the effect of spatial precipitation heterogeneity on runoff process 本文建立了雨量输入处理方法不同的方案、方案和方案三种方案,用这三个方案分别作日流量模拟与洪水过程模拟,来分析降水空间分异性对模拟水文过程的影响。 |
| 5. | By monte - carlo method the flood discharge risk is calculated with consideration of the uncertainty of flood hydrograph , and the result is compared with that without consideration of the uncertainty of flood hydrograph . it is clear that the flood discharge risk is lower when the uncertainty of flood hydrograph is considered 文章最后用蒙特卡洛法分别计算了此工程在考虑洪水过程不确定性和不考虑时泄洪风险值,比较二者的计算结果,后者的风险值明显大于前者,这说明,洪水过程不确定性对泄洪风险的影响不可忽略不计。 |
| 6. | In the first part , we compute the site design flood of given design frequency ( 0 . 01 % . 0 . 1 % . 0 . 2 % and 1 % ) using the design flood hydrograph . then we get the design reservoir inflow flood of the same design frequency by the resultant discharge method . according to the computing value we compare the site design flood and design reservoir inflow flood of different time interval 本论文以广西红水河龙滩水电站为例,在第一篇中采用洪水过程线法计算了给定设计频率为0 . 01 、 0 . 1 、 0 . 2和1的坝址设计洪水,并利用合成流量法计算了相应设计频率的入库设计洪水。 |
| 7. | In the past years , people generally considered that the effect of the uncertainty of the flood hydrograph is not the main reason that result in the flood discharge risk and even ignore its effect . in the paper , this factor is take into account during analyzing and calculating flood discharge risk 在已有的对施工导流及泄洪风险的研究中,人们普遍认为水文因子中的洪峰流量的不确定性是造成风险的主要风险因素,认为洪水过程的不确定性所带来的影响很小,可以忽略不计。 |
