Applied Paleoflood Hydrology

最近的研究表明，在适当的“自我测量”自然河流环境中，对洪水滞流沉积物和古阶段指标（SWD-PSI）的分析，可以得出准确而完整的特大洪水目录。SWD-PSI目录涵盖了过去数百年和数千年的时间，提供了关于灾难性洪水的真实物理数据，这些数据用传统方法估计是最困难的。目前的工作是利用这一科学突破，改进和标准化SWD-PSI方法；通过开发洪水古震级和年龄估算的新方法；将古洪水数据纳入洪水频率分析；建立数据收集和其他应用的标准；并研究特大洪水时空格局与区域化和气候变率的关系。该项目将支持古洪水水文学作为一个科学和工程领域健康发展所必需的学术基础设施，受益者将是专门评估自然的研究人员。特大洪水的规模、风险和后果。

Analysis of flood slackwater deposits and paleostage indicators (SWD-PSI) in appropriate "self-gaging" natural fluvial settings have proven in recent studies that they yield accurate and complete catalogs of extraordinary floods. The SWD-PSI catalogs extend hundreds and thousands of years into the past providing real physical data on the cataclysmic floods that are most problematic to estimate by conventional methods. The present work capitalizes on this scientific breakthrough by improving and standardizing SWD-PSI methodology; by developing new procedures for flood paleomagnitude and age estimation; by incorporating paleoflood data into flood frequency analysis; by establishing criteria for data collection and other applications; and by studying the spatial and temporal patterns of extraordinary floods in relation to regionalization and climate variability. The academic infrastructure necessary for the healthy development of paleoflood hydrology as a field of science and engineering will be supported by this project, and the beneficiaries will be the investigators specializing in assessing the nature, magnitude, risk and consequences of extraordinary and cataclysmic floods.
