Samenvatting
Scour is the primary cause of bridge failure in the United States. There are more than 20,000 highway bridges that are rated “scour critical.” Selected bridges have been monitored for more than ten years and valuable field data have been obtained from these bridges. This report presents the current state of practice for fixed scour bridge monitoring. It will be useful for bridge owners, in particular those responsible for bridge maintenance and safety. Information for this report was obtained through literature review, survey of the state transportation agencies, and selected interviews. (Author/publisher)
