Impact of Flooding on Pavement Drawdown Structures

Upon completion, this study will provide Iowa counties and the Iowa Department of Transportation (Iowa DOT) with a robust framework to assess and manage flood risks across Iowa's transportation infrastructure used as drawdown structures, offering several key benefits: enhanced flood risk management, cost savings, improved resilience, and strategic planning tools. The framework will enable precise evaluations of infrastructure (drawdown structures) vulnerability, allowing Iowa Counties and Iowa DOT to prioritize maintenance and allocate resources efficiently. By predicting the loss of service life under various flood scenarios,Iowa counties and Iowa DOT can implement targeted countermeasures, reducing emergency repairs. The ability to predict and mitigate flood-induced damage will result in cost savings, extend infrastructure service life, and minimize maintenance costs. The study’s focus on practical, cost-effective solutions will help optimize counties investments and enhance network resilience. Adopting recommended countermeasures will improve infrastructure’s capacity to withstand increasingly frequent and severe floods, safeguarding roads while ensuring public safety and reliability.
