SGER: Waves and Surge during Hurricanes Gustav and Ike

[0902264]飓风期间的浪涌对沿海建筑物、桥梁等结构物是一种重要的荷载，必须对其进行设计。该项目将从安装在古斯塔夫和艾克飓风路径上的水下压力表收集数据。该数据将使用低通滤波器进行分析以定义浪涌时间序列，并结合线性波动理论进行频谱分析以定义波动时间序列。这是第一次收集这样的数据。这些数据将提供重要的信息，以提高对飓风浪潮及其对海岸结构的影响的认识。它将有助于开发飓风引起的浪涌高度和沿海建筑和桥梁等结构的水压荷载模型。这些信息对政府的规划者和管理者、数值建模者、地质学家和工程师设计海岸结构以及在飓风期间将预测和观测到的破坏联系起来是有用的。

Abstract0902264The water surge during a hurricane is an important load on coastal structures such as building and bridges for which they must be designed. This project will collect data from submerged pressure gauges that were installed in the paths of Hurricanes Gustav and Ike. This data will be analyzed using low-pass filters to define the surge time series, and spectral analysis combined with linear wave theory to define the wave time series. This is for the first time that such data have been collected. This data will provide important information to improve the understanding of hurricane surges and their effect on the coastal structures. It will help in the development of hurricane induced surge heights and water pressure load models on structures such as coastal buildings and bridges. This information will be useful to governmental planners and regulators, numerical modelers, and geologists and engineers for the design of coastal structures and to correlate the predicted and observed damage during a hurricane.
