• Abstract:
  The interstate highway network is an ; important national asset. Bridges ; constituting critical nodes within ; transportation networks are the ; backbone of the transportation ; infrastructure. It is well known that ; scour is one of the major courses of ; bridge failures. In the last 30 years, ; more than 1,000 bridges collapsed in ; the United States, and about 60 ; percent failures are related to the ; scour of bridges’ foundations. Due to ; the difficulty in inspecting bridge ; scour, scour-induced failures tend to ; occur suddenly without prior warning ; or signs of distress to the structures. ; With the threat of hurricane-induced ; flooding and the fact that there is a ; significant number of coastal and ; river/bayou bridges in Louisiana, a ; more reliable inspection and ; monitoring procedure for bridge scour ; is needed.
