简介：中国城市面对高、很快增加的暴露到灾难。减少灾难危险是为灾难管理和风险减小的一项直接、有效的反措施，它要求对社会和经济的危险的首先客观的评价。对经济危险的评价是在风险评估，为有效灾难预防计划的一个前提和为紧急情况管理的一个重要的底的重要的步。这份报纸为估计经济危险开发一个模型，它各种各样的工业部门和经济密度的企业，危险和重要性的尺寸考虑。基于模型，这份报纸开发一个城市的经济危险评估系统并且在北京把它用于Haidian区域，结果帮助鉴别在它的647，块在哪儿高度并且很高度以经济脆弱，并且它为灾难前预防计划提供有用、实际的信息，灾难有准备和紧急情况管理。在这研究开发的经济危险评价模型和系统使让政府快速评估一般经济危险并且识别特定的脆弱的区域可能，做对灾难管理信息系统和决定支持系统的贡献。

简介：聚类的地震指在时空与对方一起仔细发生的地震事件。因为他们的重叠波形记录使拣第一到达困难，聚类地震的hypocenters不能被traveltime地点方法精确地决定。这里，我们使用一个反向时间的成像(RTI)方法印射聚类地震。拿直接使用波形的优点，RTI方法是有能力的印射单个小地震或浓密地散布的一些在2-D下面聚类地震地震数组。在3-D情况中，RTI方法成功地被使用从一套稀疏地分布式的表面车站用数据定位长偏移量的马甲地震。为一样的获得几何学，然而，在印射的RTI相遇挑战浓密地散布了聚类地震。当改进印射聚类地震与照明角度的更宽的范围要求一个更稠密的接收装置网络，是明显的时，与合成数据验证RTI方法的实际分辨率是必要的。在我们在三个峡区域的学习区域，我们3-D情况的测试建议在线性排列亚数组下面的一些事件有合理分辨率。

简介：下游的移动与暴风雨长度袭击的假设不到分水岭长度(Ls/L<1.0)放大在以前的研究由运动学波浪的模型显示了的山峰分泌物在无尺寸的山峰分泌物和无尺寸的暴风雨速度的分析被评估。在UrbanaChampaign在伊利诺大学在分水岭试验系统(WES)为一个塑造V的分水岭收集的以前未出版的试验性的数据，与一个运动学波浪的模型的模拟结果比较被使用。与L山峰与静止暴风雨相比解除到有限程度的s/L<1.0增加，和运动学波浪的模型说大话源于下游的移动的山峰流动的增加与Ls/L<1.0。为了评估回水的重要性，在试验性的分水岭完成，为源于在上游、下游的动人的暴风雨的表面流量的模拟的运动学波浪、动态波浪的模型的精确性被评估利用一样的试验性的数据。运动学波浪的模型模仿在上游的移动暴风雨相当好，即模型的NashSutcliffe系数分别地为等于、不等于分水岭长度的暴风雨长度适合等于0.948和0.831的效率。而，运动学的波浪模型实质地过高估计下游地移动暴风雨，和收益的山峰分泌物通常更差比为在上游的动人的暴风雨适合，即为有等于、不等于分水岭长度的长度的暴风雨的NSE平等者到0.867和0.674分别地。动态波浪的模型模仿下游的移动暴风雨相当好，即为有等于、不等于分水岭长度的长度的暴风雨的NSE平等者到0.843和0.879分别地，显示回水显著地为甚至这个简单试验性的分水岭影响流量。考虑到那个暴风雨运动实质地没放大山峰分泌物，在标准hydrologic设计做的静止暴风雨的假设似乎合理、足够。
