John Dobosiewicz is a Ph.D. Candidate in the Department of Geography at Rutgers University in New Brunswick, New Jersey. His research interests are in Physical Geography and the application of Geographic Information Systems (GIS) to the study of hazards, especially in coastal environments. He is also an adjunct instructor in the Department of Geography at Rutgers University and the Department of Geology and Meteorology at Kean University in Union, New Jersey.


Geographic information systems (GIS) are increasingly used in coastal hazard research for coastal management and for analysis of information following major storm events because of their ability to evaluate multiple data sets. Digital Previous HitfloodNext Hit zone data sets and qualitative post storm Previous HitfloodNext Hit water level observations exist for Raritan Bay, New Jersey, an urban estuary. A desktop GIS is used to overlay different digital data sets containing Previous HitfloodNext Hit zone information and determine the number and length of roads that are within the Previous HitfloodNext Hit zone. The elevation of the 1% probability Previous HitfloodNext Hit zone on the digital elevation model is determined from a long-term tidal record at Sandy Hook, New Jersey and roads flooded during a major coastal storm in December 1992. In this article, 1% probability Previous HitfloodNext Hit zones, also called the 100-year Previous HitfloodNext Hit zone, are calculated using digital elevation models and compared to 1% probability Previous HitfloodNext Hit zones from the Federal Emergency Management Agency and the New Jersey Department of Environmental Protection. The 1% probability Previous HitfloodNext Hit is typically used for Previous HitfloodNext Hit zone management. The results indicate that digital elevation models and GIS can be used to identify roads that would be flooded by the 1% probability Previous HitfloodNext Hit comparable to roads found on existing Previous HitfloodTop zone maps.
