RAPID: TYPHOON HAIYAN - ENVIRONMENTAL IMPACTS ON THE PHILIPPINES

这份快速报告将比较2013年台风海燕和2004年印度洋海啸对环境的影响。将收集台风海燕的沉积沉积物，并与之前收集的印度洋海啸沉积沉积物进行比较，以测量陆地高程、风暴潮流量和沉积物沉积。还将确定溢流层内的沉积后变化。反过来，这两个数据集的差异将与沉积物侵蚀、输送和沉积的物理学联系在一起。实地研究将集中在莱特湾海岸线，该地区在台风海燕期间遭受了最大的风暴潮。台风海燕过后，将立即收集风暴潮及其沉积物的易腐烂数据和重要特征。同一地点将在一年后重新访问和重新取样，以评估热带环境中沉积后变化的程度。2004年印度洋海啸沉积物的采样间隔与此类似。该项目将收集一个独特的数据集，说明海滩侵蚀、冲刷沉积和岛屿决口造成的海岸变化的性质、规模和空间变异性。该项目补充了现有国际研究小组的研究，并将进一步完善严重风暴对沿海影响的预测模型。此外，这项研究还包括来自美国、新加坡和菲律宾的研究人员之间强有力的国际合作，以及对这三个国家的研究生和博士后的培训。这一快速奖由地貌学和土地利用动态计划以及国际和综合活动办公室共同资助。

This RAPID will compare the environmental impacts of the 2013 Typhoon Haiyan and the 2004 Indian Ocean Tsunami. Sedimentary deposits of Typhoon Haiyan will be collected and compared with previously collected sedimentary deposits of the Indian Ocean Tsunami in order to measure land elevation, storm surge flow, and sediment deposit. Post-depositional change within overwash deposits will also be determined. In turn, the differences from these two datasets will be linked to the physics of sediment erosion, transport, and deposition. Field research will focus on the Leyte Gulf coastline, which was the region that suffered the largest storm surge during Typhoon Haiyan. Perishable data and vital characteristics of the storm surge and its deposits will be collected immediately following Typhoon Haiyan. The same site will be revisited and resampled a year later to assess the degree of post-depositional change in a tropical environment. The 2004 Indian Ocean Tsunami deposits were sampled at similar intervals. This project will collect a unique dataset that will illustrate the nature, magnitude and spatial variability of coastal changes from beach erosion, overwash deposition and island breaching. The project complements the research of existing international research groups and will further refine predictive models of coastal impacts from severe storms. Additionally, the research includes a strong international collaboration between researchers from the US, Singapore, and the Philippines as well as training of graduate students and postdocs from all three countries. This RAPID award is co-funded by the Geomorphology and Land-use Dynamics Program and the Office of International and Integrative Activities.
