Mapping Statewide Flash Flood Potential Index (Ffpi) In Indiana, Evan Bentley Apr 2011

Mapping Statewide Flash Flood Potential Index (Ffpi) In Indiana, Evan Bentley

Symposium on Research and Creative Expression (SORCE)

National Weather Service (NWS) employees must make forecasting decisions on a daily basis. These forecasts are important to save people’s lives and property. One area where the NWS has very little guidance is flash flood prediction. A GIS project was undertaken to create a preliminary flash flood potential index map for the state of Indiana to help weather forecasters issue more accurate flash flood watches and warnings. In this project, slope, soil type, land use, and forest canopy layers were used to create an index map for flash flood potential.

Tornadic Behavior Related To Land-Falling Tropical Cyclones In The United States, Jaclyn M. Ritzman, D S. Arndt, M C. Kruk

Symposium on Research and Creative Expression (SORCE)

The 2004 and 2005 North Atlantic hurricane seasons were among the most active and economically devastating for the United States, during which 18 tropical cyclones (TCs) made landfall. These TCs were analyzed using the International Best Tracks Archive for Climate Stewardship (IBTrACS) and Local Storm Reports (LSR) datasets to determine whether they produced tornadoes within a preferred quadrant and distance from the center of circulation of the TC. The land-falling TCs were tracked and analyzed through their weakening stages with tornado reports being classified based on the strength of the TC at the time of occurrence. Tornado reports were not …
