Taking Luoshan Station as an example for the flood risk assessment, the present paper makes a quantitative analysis on the effect of the waterway silt up on the flood discharge with the author's self established general assessment mode. In recent decades, serious flood and high level water passing through a waterway with small discharge capacity has become more and more frequent happenings in China. Such discharge difficulty has been mainly caused by the sledge silt up in the waterway. So how to assess the effect of the sledge silt up and increase the discharge capacity has become an urgent need. Since the factor of waterway silt up is often ignored in the traditional flood research, a general risk assessment mode has to be established, which involves two parts. One is to analyze the effect of the silt up situation on the flood frequency. For this purpose, a water level frequency curves before and after the silt up formation has to be drawn up and the flood frequency change has also to be measured in a statistical manner so that the effect of the silt up on the flood can be analyzed. Then, a general mode is used to observe the data collected in Luoshan to show how to operate the mode. To this end, the authors are engaged in continuous measuring and calculating the water level of Luoshan from 1954 to 1985 before the silt up deposition with an empirical formula by means of a multivariate linear regression, and the effect of the silt up deposition on the flood frequency to analyze the flood risk. Two conclusions are finally obtained as follows. First, the water level frequency increases because of silt up deposition. Second, according to the change of the two indexes before and after the deposition, the silt up deposition has made it possible for the lower reach to commit more flood risk. Furthermore, with the rising of water level of Luoshan, the water level in Dongting Lake is likely to rise too. Hence, more flood risk with Dongting.

建立了考虑泥沙淤积的洪灾风险估计的一般模式 ,并以螺山站为例 ,定量分析了泥沙淤积对洪水频率和洪灾风险的影响。结果表明 ,考虑泥沙淤积对水位频率会产生影响 ,在相同水位下 ,泥沙淤积会缩短洪水的重现期 ,水位越低 ,频率变化越大。对于相同频率的洪水 ,泥沙的淤积使水位抬升 ,且频率越小 ,水位变化越小。另外 ,泥沙淤积使洪灾风险增加 ,加重了洪灾的损失。螺山下游的洪灾风险率从 6%增加到 2 2 .5% ,水位超高期望值从 0 .1 1 4 m增加到 0 .2 33 m。

Based on the DEM of 1∶50 000, 1∶250 000 national digital topographical map, land use map of 1∶100 000 and the hydrologic data of counties Dingbian, Jingbian, Zichang and Yanchuan, flood risk assessment in the Shaanxi section along the West-East Pipeline Project (WEPP) was conducted under support of ARC/INFO. Four factors including topography, precipitation, land use and project vulnerability were selected. Firstly three raster coverage maps were made by analyzing the factors. And then the flood risk assessment map was derived by overlapping the coverage. The risk degrees were divided into five levels: Class 1, Class 2, Class 3, Class 4 and Class 5. The result (indicates) that flood risk degrees are mainly Class 1, Class 2 and Class 3 in the west of the Shaanxi section along the WEPP, which characterizes less precipitation, higher elevation and lower town density. The high flood risk degrees are Class 4 and Class 5 in Zichang and Yanchuan Counties, which include Xiuyan River,Yongpingchuan River, Qingjian River, river valley and the region along the Yellow River.

在ARC/INFO的支持下,利用1∶5万的DEM,1∶25万全国数字化地形图,以及定边、靖边、子长和延川4县1∶10万土地利用图与多年水文统计资料,通过叠加分析,对西气东输工程沿线陕西段的洪水风险进行了评估。选取地形、降水、土地利用和社会经济易损性4个因子进行综合分析,分别得到了它们对洪水影响的栅格图,通过对各栅格图的叠加,得到了洪水风险分级图。结果表明,管线西部的定边和靖边,其降水量较低,海拔较高,村镇密度相对较低,洪水风险较低,主要为1级、2级和3级;管线西部的子长和延川县,其地形起伏大,降水量大,植被覆被较低,村镇密度大,洪水风险较大,主要为4级和5级,风险最高的地区集中在秀延河、永坪川、清涧河、东部丘陵沟壑区河谷平原、黄河周围地区及子长县的大部分地区。
