*** 9732129 Street The project is for a one year study to explore the physics of topographically- induced turbulence impinging on a free-surface, and to explore the feasibility of surface detection of bottom topography in a variety of circumstances. The PI will perform a Large-Eddy Simulations (LES) with a free- surface for flows in four scenarios: 1) a single polynomial hill, 2) two- dimensional sinusoidal topography, 3) three-dimensional sinusoidal topography, and 4) a channel and shoal configuration. The numerical output will be analyzed to investigate patterns of stress and advection on the surface which may be used to identify underlying topography. ***

*** 9732129街 该项目为期一年，旨在探讨地形引起的湍流冲击自由表面的物理学，并探讨在各种情况下探测海底地形的可行性。 PI将在四种情况下使用自由表面对水流进行大涡模拟（LES）：1）单一多项式山丘，2）二维正弦地形，3）三维正弦地形，以及4）水道和浅滩配置。 将对数值输出进行分析，以研究表面上的应力和平流模式，这些模式可用于识别底层地形。 ***
