Vulnerability of United States Bridges to Potential Increases in Flooding from Climate Change

Citation:

Vulnerability of United States Bridges to Potential Increases in Flooding from Climate Change.

Impact/Purpose:

To assess the potential impacts of increased river flooding from climate change on U.S. bridges.

Description:

This study assesses the potential impacts of increased river flooding from climate change on bridges in the continental United States. Daily precipitation statistics from four climate models and three greenhouse gas (GHG) emissions scenarios (A2, A1B, and B1) are used to capture a range of potential changes in climate. Using changes in maximum daily precipitation, changes are estimated to the peak flow rates for the 100-year return period for 2,097 watersheds. These estimates are then combined with information from the National Bridge Inventory database to estimate changes to bridge scour vulnerability.
