Japan JSPS Program: Experimental Modeling of Sandy Tsunami Deposits

摩尔9804832该奖项为安德鲁·摩尔博士在日本仙台东北大学灾害控制研究中心设立的为期12个月的日本科学促进会博士后奖学金提供支持。Moore博士将与DCRC教授Fumihiko Imamura博士合作开展一个名为“桑迪海啸沉积物的实验建模”的研究项目。最近的几次海啸突显了这样一个事实，即海啸经过的最持久的记录之一是它留下的沙质碎片。这些海啸沉积物往往是科学家拥有的史前海啸曾经袭击过海岸的唯一证据。这项拟议的研究旨在确定海啸沉积的一般特征，包括总体几何形状、沉积结构和粒度模式。这些信息可以用来帮助识别史前海啸沉积物，并可以根据它们的沉积物估计海啸的规模和速度。这项研究涉及在实验室的波浪水池中产生小型海啸，并确定波高、波速、颗粒大小和颗粒密度的变化如何影响海啸沉积物的特征。***

Moore 9804832 This award supports a 12 month Japan Society for the Promotion of Science (JSPS) Postdoctoral Fellowship for Dr. Andrew Moore at the Disaster Control Research Center (DCRC), Tohoku University in Sendai, Japan. Dr. Moore will work with Dr. Fumihiko Imamura, Professor DCRC, on a research project entitled, "Experimental Modeling of Sandy Tsunami Deposits." Several recent tsunamis have highlighted the fact that one of the most persistent records of the passage of a tsunami is the sandy debris it leaves behind. These tsunami deposits are often the only evidence scientists have that prehistoric tsunamis once struck a coast. The proposed research is designed to determine the general features of tsunami deposits, including overall geometry, sedimentary structures, and grain-size patterns. This information can be used to help identify prehistoric tsunami deposits, and to allow estimation of the size and speed of tsunamis from their deposits. The research involves producing small tsunamis in a laboratory wave tank and determining how changes in wave height, wave velocity, particle size, and particle density affect the features of tsunami deposits. ***
