About the research

The goal of this study is to complete a comprehensive evaluation of the flood reduction benefits of existing on-road structures (ORS). This work will be performed in five selected HUC12s in Iowa. To accomplish this objective the research team will use the process-based hydrologic model GHOST to run multi-year continuous simulations using both historic precipitation conditions as well as increased precipitation conditions that represent the projected changes in heavy precipitation by the mid-and late-21st century.
