The Yellow River Delta area is located in the east of sandong Province east of China. Floods in this area are caused by two hydrological conditions. One is the rairstorm in the late summer and early fall, and another is the ice run in the winter. In the past more than 130 years, the floods happened about fifty times (including serious ten times) in the delta area. The flood risk will continuosly exist if the water and ice regimet and silt deposit can not be changed basically. So the WIRWIS has been established...

The Yellow River Delta area is located in the east of sandong Province east of China. Floods in this area are caused by two hydrological conditions. One is the rairstorm in the late summer and early fall, and another is the ice run in the winter. In the past more than 130 years, the floods happened about fifty times (including serious ten times) in the delta area. The flood risk will continuosly exist if the water and ice regimet and silt deposit can not be changed basically. So the WIRWIS has been established by using ARC/INFO GIS. It is very important for developing agriculture, oil industry, and protecting ecologic environment in the delta area.The design of the WIRWIS is first topic. This topic describes a goal and application modules of the WIRWIS. According to the goal, the display module of maps and geo-data, the module of map query, the analytical module and the evaluation module of flood loss have been designed.The second topic is data organization. It is crucial for establishing database of the WIRWIS. So, the database is divided into some layers. They are terrain, water, Yellow River course, landuse, residence, oilwell, and factory etc. Each layer stores only one type of geographic information and related attribute information. In this way it is easy for maintaining and using.The third topic is the establishment of the WIRWIS method. Data collection is a basic step of this topic. By using ARC/INFO GIS, all geographic and stat istical data have been input into-the computer. In order to build the database, geographic attribute information has also been input after coverages (files in ARC/INFO) processed.Finally some application study has been done. From a 3-D DTM the best flood discharge route has been found. After a flood discharge zone created, submerged loss can be evaluated. So a rescuing plan can be made soon.

The flood risk map compilation is one of the key assignments in flood plain management. A compiling method of flood risk map and its applications are imroduced in this paper. The compiling procedures are as follows:1. to generalize river networks in the plain so as to simulate natural river conditions; 2. to calculate water stage and discharge by using 1-D unsteady open channel flow numerical computation; 3. to compare water stage with DEM (Digital Elevation Model) ; 4. to delimit the regions...

The compiling procedures are as follows:1. to generalize river networks in the plain so as to simulate natural river conditions; 2. to calculate water stage and discharge by using 1-D unsteady open channel flow numerical computation; 3. to compare water stage with DEM (Digital Elevation Model) ; 4. to delimit the regions where the elevations are lower than water stage as flood risk regions.The flood risk map can be applied to: 1. analysis of flood status; 2. evaluation of losses of flood disaster; 3. determination of land price and disaster insurance investment in flood risk regions; 4. policy-maker assistance in hazard mitigation and prevention; 5. distribution of industry, agriculture and residential settlement; 6. special map applications.

洪涝风险图的编制,是洪涝平原管理中的一项重要内容,对洪涝平原生产布局和人类经济活动具有指导作用。本文介绍了一种洪涝风险图的编制方法。首先概化平原内河网,用明渠一维非恒定流模拟水流运动,得到各地的水位和流量,比较水位和数学地形模型(DEM)的高程,将水位高过DEM的地方划为洪涝危险区。本文以太湖流域湖西区为例作出洪涝风险图,并且介绍了洪涝风险图在国民经济部门的应用。

Comparisons were made among comprehensive shoreline changes during the high tide line periods of the Yellow River delta in 1855,1954,1976 and 1992.The results show that the shoreline moved towards the sea in the river flowing period,and retreated in the non flow period because of the wind,wave and tidal current.And dynamic process of the delta shoreline along the Qingshuigou course was also analyzed by using the isobath of -2m,and from the...

Comparisons were made among comprehensive shoreline changes during the high tide line periods of the Yellow River delta in 1855,1954,1976 and 1992.The results show that the shoreline moved towards the sea in the river flowing period,and retreated in the non flow period because of the wind,wave and tidal current.And dynamic process of the delta shoreline along the Qingshuigou course was also analyzed by using the isobath of -2m,and from the analysis,it is found that the land forming rate is becoming slower than before,indicating a tendency that the river mouth is developing from the original increasing to the terminal atrophy.And also the environmental geologic effect caused by shoreline changes was discussed in the paper.The most important effect on the river estuary is the high flood risk that can induce riverbed deposition and continuous water level rising.

以 18 5 5、195 4、1976年和 1992年的高潮线对比分析黄河三角洲海岸线的整体变化情况 ,表明在行河岸段 ,海岸线迅速向前淤进 ,而在非行河岸段 ,由于风浪、海流等侵袭 ,岸线后退。采用 1976、1982、1987、1990年和1995年近海区实测水深资料 ,以 - 2 m等深线的变化来研究清水沟流路河口三角洲岸线的动态变化过程 ,发现河口造陆速度逐渐变慢 ,反映出河口尾闾从初期发育走向萎缩的趋势。岸线变化的环境地质效应表现在多方面 ,对下游河道冲淤影响最重要的是河床主槽持续淤积及同流量水位的抬升所带来的防洪风险的增大。
