Europeans offer bridge scour and stream instability solutions
Article Abstract:
Officials of the Federal Highway Administration and from the transportation sector are in Europe to study scour countermeasures at bridges and flood control structures. They found that scour is not a problem for the public works in Germany, Switzerland and the Netherlands since countermeasures are included in their designs. The UK as well as the US retrofits their existing infrastructure with scour countermeasures. They have also discovered that their European counterparts make extensive use of ripraps or stones in combination with geotextiles or granular filters.

On scour's frontier
Article Abstract:
The Bonner Bridge in North Carolina is scheduled for repair after more than 30 years of withstanding the harsh effects of hurricanes and northeasters. Parsons Brinckerhoff Quade & Douglas Inc was commissioned to provide the complete plan of the bridge's replacement. Computer and physical models were used to analyze scour, help engineers design a better bridge and reduce construction expenditures.
