Tornadoes have a heavy presence in the Southeastern United States and have a strong impact on not only the people but the landscape as well. Tornadoes with a rating of EF-2 or higher have the potential to destroy vegetation in their paths and even take out entire forests. When a strong or violent tornado affects an area that was once heavily forested, heavy impacts on the hydrology and geomorphology can take place. Soils that were once loose due to the vegetation now become compacted with a significant decrease in infiltration, therefore leading to increased runoff, soil erosion, and sedimentation. The surrounding community can then be faced with flooding issues, widening streams, and streams, rivers, and/or lakes polluted with excessive amounts of sediment. One the evening of March 19, 2018, an EF-3 level tornado ripped through the city of Jacksonville along with the Jacksonville State University campus, damaging many of the buildings and eliminated a lot of vegetation. This project analyses the post tornado impacts on the hydrology of a headwaters watershed that originates on the JSU campus as well as providing aerial imagery and Geographic Information Systems data of the affected watersheds. This project also analyses the potential impacts in the context of climate change and the increasing frequency of tornadoes.
