Key Points:
- We use delft3d-fm numerical model to build a hurricane ike model. 
- We validated the model results with observaed in water level and wave and they fit well.

Research Overview:
Hurricane Ike, which struck the United States in September 2008, was the ninth most expensive hurricane in terms of damages. It caused nearly $30 billion in damage, of which nearly $12B were insured losses, after making landfall on the Bolivar Peninsula, Texas. 
We used the Delft3d-FM/SWAN hydrodynamic and spectral wave model to simulate the storm surge inundation around Galveston Bay during Hurricane Ike. Damage curves were established through the eight hydrodynamic parameters (water depth, 
flow velocity, unit discharge, flow momentum flux, significant wave height, wave energy flux, total water depth (flow depth plus wave height), and total (flow plus wave) force) simulated by the model. 
We found that the damage curves are sensitive to the model grid resolution, building elevation, and the number of stories. 
 

Methodology:
The establishment of a hurricane hydrodynamic model requires adequate input files. In this study, simulations of Hurricane Ike were conducted using the Delft3D-FM hydrodynamic software. 
The model was driven by input files such as the grid of the study area, tidal boundaries, bathymetry files, hurricane wind field, and atmospheric pressure field. 
The silumation time of the model is from Sep.07.2008 to Sep.17.2008.
This dataset allows for the replication of the hurricane model. After the model was built, validation was performed using NOAA's water level and wave data to verify the model outputs.
