以三峡枢纽的防洪控制系统为研究对象,从洪水分析的角度,利用混合型分布和风险理论,对各种不同类型和各种频率洪水情况下的工程安全、防洪效益(以减少淹没田亩数表示)等综合影响进行了系统风险评估,获得了表示三峡大坝安全的坝前特征水... 以三峡枢纽的防洪控制系统为研究对象,从洪水分析的角度,利用混合型分布和风险理论,对各种不同类型和各种频率洪水情况下的工程安全、防洪效益(以减少淹没田亩数表示)等综合影响进行了系统风险评估,获得了表示三峡大坝安全的坝前特征水位、沙市防洪控制水位和坝上下游洪水淹没损失的风险评估值,并对三峡工程设计洪水进行了风险分析。结果表明,三峡水库在正常蓄水位情况下超过该水位的风险率小于相应概率,水库设计水位有较高的安全可靠性。建库后,沙市水位风险和荆江、城陵矾地区淹没损失显著减小,三峡工程具有巨大的防洪效益。 展开更多

In the State of Santa Catarina, Brazil, especially in the Itajai valley, there are records of accidents and disasters mainly associated to landslides and floods, which have caused significant damages and losses, including human lives. In order to make the coexistence with such natural disasters possible, most particularly with floods, a integration is required among the technical, political, environmental, and human knowledge. Measures that encompass integrated actions for the entire river basin, with the help from an updated technical cadastre and tools, such as the GIS, allow the development of planning tools that might effectively help the people to live with the water, or else to cope with floods in a more appropriate manner. This paper attempts to propose a methodology for urban flood control, based on the integration among the several public entities involved in the flood control, along with the CTM (Multipurpose Technical Cadastre) and GIS tool. In order to solve or minimize the problems, the model proposed here aims at promoting a balance between the agents involved, and enables to rank the degrees of importance assigned to the different needs, thus allowing to eliminate or to improve those areas and processes that are duplicated or superimposed. 展开更多
