The Iowa Flood Information System (IFIS) is a web platform developed by the Iowa Flood Center (IFC) at the University of Iowa. IFIS provides a user-friendly and interactive environment for over 1000 communities in Iowa regarding flood conditions, flood forecasts, data visualizations, and flood-related data, information and applications.

The IFIS provides community-centric watershed and river characteristics, weather (rainfall) conditions, and streamflow data and visualization tools. Interactive interfaces allow access to inundation maps for different stage and return period values, and flooding scenarios with contributions from multiple rivers. Real-time and historical data of water levels, stage heights, and rainfall conditions are available in the IFIS by streaming data from automated IFC bridge sensors, USGS stream gauges, NEXRAD radars, and NWS forecasts. 2D and 3D interactive visualizations in the IFIS make the data more understandable to general public. Users are able to filter data sources for their communities and selected rivers.

The IFIS includes a rainfall-runoff forecast model to provide a five-day flood risk estimate for over 1000 communities in Iowa. Multiple view modes in the IFIS accommodate different user types from general public to researchers and decision makers by providing different level of tools and details. River view mode allows users to visualize data from multiple IFC bridge sensors and USGS stream gauges to follow flooding condition along a river.

The IFIS helps communities make better-informed decisions on the occurrence of floods, and alerts communities in advance to help minimize damage of floods.
