RAPID: Flood and Erosion Reconnaissance: Hurricanes Irene and Lee, Upstate New York and Western New England

2011年8月的最后一周和9月的第一周，飓风艾琳和李带来了两次大降雨，美国东北部从弗吉尼亚到新英格兰的大部分地区经历了毁灭性的、历史性的洪水。该合同的目的是记录洪水造成的破坏，与RPI的教师和学生团队进行侦察，并与各种机构(如国家DOT？2012年夏天，美国地质勘探局（USGS）和联邦应急管理局（FEMA）共同撰写了一份综合报告。为了获得这些极易腐烂和有价值的洪水数据，需要迅速作出反应。现场工作将尽快开始，大部分工作将在冬季来临前的几个月内完成。明年春天可能会做一些实地工作，比如跟进和记录一些有趣和重要的案例研究。报告的编写工作将在2011- 2012年冬季继续进行，包括与上述机构的协调与合作。其目的是在2012年夏天发布一份最终报告。该报告还将参考其他机构发表的其他报告和数据来源，并提供链接。收集的典型数据将是水文数据，包括高水位、流量和洪水复发间隔；进行边坡和滑坡稳定性分析所需的岩土工程数据；与桥梁和大坝破坏有关的冲刷和侵蚀数据；以及摄影和激光雷达测量等文档。这些数据中的大部分将由其他机构获得。即使保守估计，纽约州北部、新英格兰西部和宾夕法尼亚州北部地区的洪水损失也高达数百亿美元。这次水灾的损失必须记录在案。根据国会最近的指示，联邦应急管理局正在修订其洪水绘图程序，这些洪水可能会对联邦应急管理局的程序和国家洪水保险计划产生影响。对美国业主的保险费率的潜在影响是数十亿美元。这一事件具有历史意义，我们可以从中了解到很多关于水文、洪水、河流流量、侵蚀等方面的信息。这种一生只发生一次的事件（我们希望）必须得到充分的记录和研究。具体数字尚未公布，但很明显，许多水体的水位超过了有记录以来的最高水平，许多水体经历了500年一遇的洪水。

As a result of two large rainfall events from Hurricanes Irene and Lee around the last week of August, 2011 and the first weeks of September, 2011, a large part of the northeast US from Virginia to New England has experienced devastating and historic levels of flooding. The intent of this award is to document the flood damage, performing reconnaissance with a team of RPI faculty and students, interacting with various agencies such as State DOT?s, USGS and FEMA, and producing a comprehensive report in the summer of 2012. A rapid response is required to obtain this highly perishable and valuable flood data. The field work will begin as soon as possible, most will have to be done in the next few months prior to winter weather. It may be possible to do some field work next spring 2012, such as follow up and documentation of interesting and important case studies. Work on the report will continue during this winter 2011-12, including coordination and cooperation with the agencies noted above. The intent is to produce a final report summer of 2012. The report will also reference and provide links to other reports and sources of data published by other agencies. Typical data collected will be hydrological, consisting of high water levels, flow quantities and flood recurrence intervals; geotechnical data required to do slope and landslide stability analyses; scour and erosion data related to bridge and dam failures; and documentation such as photography and LIDAR measurements. Much of this data will have been obtained by other agencies. Even conservative estimates of flood damage in upstate NY, Western New England and Northern PA regions are in the tens of billions of dollars. This flood damage must be documented. FEMA, as recently directed by Congress, is in the process of revising its flood mapping procedures, and these floods will likely have an impact on FEMA procedures and the National Flood Insurance Program. The potential impact on insurance rates for U.S. property owners is in the many billions of dollars. This event is historic, and much can be learned about hydrology, flooding, river flow, erosion and more. This once in a lifetime (we hope) event must be well documented and studied. The numbers are not in, but it is clear that many water bodies have exceeded all time recorded levels, and many have experienced 500 year floods.
