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.

这种快速将比较2013年台风海扬和2004年印度洋海啸的环境影响。 将收集台风海扬的沉积沉积物，并将其与先前收集的印度洋海啸沉积物进行比较，以衡量土地升高，风暴潮流和沉积物沉积物。 还将确定倒入沉积物内的沉积后变化。 反过来，这两个数据集的差异将与沉积物侵蚀，运输和沉积的物理学联系起来。 现场研究将重点关注莱特湾海岸线，该地区是台风海扬期间风暴潮最大的地区。 台风海扬后，将立即收集风暴潮及其沉积物的易腐烂数据和重要特征。 一年后，将重新访问和重新采样同一地点，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以类似的间隔进行了采样。 该项目将收集一个独特的数据集，该数据集将说明海滩侵蚀，夸大沉积和岛屿破裂的沿海变化的性质，大小和空间变化。 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中沿海影响的预测模型。 此外，该研究包括美国，新加坡和菲律宾研究人员之间的强烈国际合作，以及对三个国家的研究生和博士后的培训。 这项快速奖项由地貌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。
