Abstract
Simulation of Storm Surge Flooding Track: Climate, Weather and Atmosphere Author(s): John Stanton, Kelly Knee A simple simulation of storm surge flooding was developed by comparing predicted surge heights with coastal land elevations. This method provides a very quick assessment of flood hazard areas in the event of a predicted storm surge. In this case the storm surge heights were taken from the National Weather Service's application of the SLOSH model for a category II hurricane, and the National Elevation Dataset's 1/3 arc second elevation data was used for coastal land elevations. A custom ArcObjects tool creates a polygon shapefile of the NED elevations below the designated surge height. This polygon represents flooding from a particular storm surge and can be used with aerial photographs and 3D building models to more easily identify areas at-risk. The ability to build custom tools for ArcMap using ArcObjects allows for the rapid analysis of data, while 3D visualization tools provide a data rich platform for interpreting flood predictions.
