XBeach Bottom Friction Scenarios: Model Inputs and Results

Using the numerical model XBeach version 4926 (Roelvink and others, 2009), various bottom friction scenarios were simulated for hurricanes Ivan (2004) and Katrina (2005) at Dauphin Island, Alabama as described in Passeri and others, 2018. The XBeach model setup requires the input of a merged topographic and bathymetric digital elevation model (DEM), and inputs of wave spectra (based on significant wave height, peak wave period and wave direction) and water level (tide and surge) time series. Model inputs and outputs in the form of topography and bathymetry are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to Passeri and others, 2018.

本研究采用数值模型XBeach 4926版本（Roelvink等，2009），针对2004年伊万飓风与2005年卡特里娜飓风，在阿拉巴马州多芬岛开展了多组底摩擦情景模拟，相关模拟设置详见Passeri等（2018）的研究。XBeach模型的配置需输入融合地形与水深的数字高程模型（Digital Elevation Model, DEM），同时需输入基于有效波高、峰值波周期与波向的波谱数据，以及包含潮汐与风暴增水的水位时序数据。本数据集发布了以地形与水深形式存储的模型输入与输出数据。如需了解模型输入数据生成及模型输出地形与水深数据可视化的更多细节，请参考Passeri等（2018）的研究。
