FHWA Climate Resilience Pilot Program: Iowa Department of Transportation

River floods can persist for days or weeks in river basins with gently sloping landscapes like those found in parts of Iowa. The basins drain slowly, creating an extended period over which new rainfall can amplify a flood pulse in the river system and flood bridges and adjacent roadways. To evaluate future flood conditions, Iowa Department of Transportation (Iowa DOT) developed a methodology to integrate climate projections of rainfall within a river system model to predict river flood response to climate change. Iowa DOT tested this methodology in two river basins to evaluate its ability to produce scenarios of future flood conditions. They analyzed the potential impact of the predicted future floods on six bridges to evaluate vulnerability to climate change and extreme weather and inform the development of adaptation options.
