Cooperative Research: Three-Dimensional Effects of Tsunami Run-up Onto a Coastline

海啸（地震海浪）研究的主要工程问题之一是波浪上升的最后阶段，滑坡和陆上流动-沿海过程，可对人口稠密的沿海社区造成严重破坏。这些影响通常因问题的三维方面而变得复杂，包括对海岸结构的影响和对近岸水深的传播；这些长波对它们有很高的反应。现有的海啸上升研究大多是二维的：有必要在实验和数值技术方面取得进展，以便了解海啸上升的三维特征。​这个研究项目是几位研究人员的共同努力，通过创新地结合现代实验技术来研究这一现象，数学理论和数值模型。Philip l - f博士。康奈尔大学的Liu和哈佛大学的George F. Carrier博士负责理论和数值研究；华盛顿大学的Harry H. Yeh博士负责小规模实验项目；南加州大学的科斯塔斯·e·Synolakis博士和美国陆军工程兵团海岸工程研究中心（CERC）的迈克·布里格斯先生正在领导一个研究小组进行这项研究在位于ms维克斯堡的CERC进行的大规模实验，该项目的目标是：(1)更好地理解海啸三维上升过程中的物理现象，识别海啸三维上升过程中的重要物理参数；(2)推进三维自由面流动数值模拟技术；（三）制定实验室实验的解析解和数值解；(4)建立实验结果数据库，为今后不同数值模型的验证提供依据。这项研究计划将促进和加强大学和各种政府机构和实验室的研究人员之间的互动。

One of the primary engineering concerns in tsunami (seismic sea wave) research is the final stage of wave run-up, run-down and overland flows - coastal processes which can cause severe damage in a populated coastal community. These effects are usually complicated by the three-dimensional aspects of the problem, including impact with coastal structures and propagation over the nearshore bathymetry; to which these long waves are highly responsive. Most of the existing research on tsunami run-up is primarily two-dimensional: There is a need to make advances in experimental and numerical techniques so as to understand the three-dimensional features of tsunami run-up. This research program is a coordinated effort among several researchers to investigate this phenomenon through innovative combinations of modern experimental techniques, mathematical theories and numerical models. Dr. Philip L.-F. Liu at Cornell University and Dr. George F. Carrier of Harvard University are responsible for the theoretical and numerical study; Dr. Harry H. Yeh at the University of Washington is in charge of the small-scale experimental program; and Dr. Costas E. Synolakis of the University Southern California and Mr. Mike Briggs of the Coastal Engineering Research Center (CERC) of the U.S. Army Corps of Engineers are leading a research team to carry out the large-scale experiments at CERC in Vicksburg, MS. The goals of the program are: (1) To achieve a better understanding of the physical phenomenon and to identify important physical parameters involved in three-dimensional tsunami run-up; (2) to advance the numerical modeling techniques for simulating three-dimensional free surface flows; (3) to develop analytical and numerical solutions for the laboratory experiments; and (4) to generate a data-base of experimental results for future verification of different numerical models. This research program will facilitate and enhanceinteractions between researchers in universities and various government agencies and laboratories.
