Document Type: Proceeding Paper

Part of: Hydraulic Engineering


The proposed procedure to determine the risk of river bridge failure is based on observations and analysis of river bridge failure data of more than 300 U.S. bridges, 180 South African bridges and 100 New Zealand bridges. The objective of the guideline is to offer a consistent, affordable procedure which can be used to determine the risk of river bridge failure. The procedure has two Risk Assessment options and one Risk Management option. The procedure can be used for various purposes, e.g. prioritizing maintenance of river bridge systems, or selecting between optional river bridge designs.
