Use of ArcGIS to examine flash flooding variables and produce a flash flood risk assessment and inundation model for Terre Haute, Indiana. Risk assessment, produced within ArcGIS, indicates that an increase in developed area leads to an increase in very high flash flood risk area and majority of very high risk area resides in developed areas of Terre Haute. Inundation model, produced using ArcGIS and Python, indicates that the proposed model can determine locations of flash flooding, but spatial extent of model predicted flooding is not reliable based on field validation.
