2014 Big Sioux River flooding in Akron, IA.
A project based in the Big Sioux River Watershed in eastern South Dakota used innovative technology developed by the Iowa Flood Center to create a web-based system called the South Dakota Flood Inundation System (SDFIS).
Thanks to the IFC’s leadership and expertise, South Dakota was able to develop a flood alert system similar to the Iowa Flood Information System (IFIS). SDFIS will include inundation maps showing the extent and depth of predicted flood waters, real-time weather and stream conditions and forecasts, and flood alerts for approximately 50 locations.
South Dakota officials will use SDFIS to mitigate flood impacts significantly affecting both people and infrastructure. The system will allow decision-makers to respond to and prepare for severe flood events under a range of changing climatic conditions, reducing future flood risk.
As extreme weather events become more frequent and intense, web-based technologies such as this will provide critical resources that can be expanded to serve other parts of the United States and beyond. View more here.
