The Scour at Bridges Management Program in Rhode Island

Abstract:

The Rhode Island Department of Transportation (RIDOT) has developed and implemented a comprehensive two-phase scour susceptibility program for screening and assessment of scour at bridges. Phase I of the program involved screening of all bridges over water to identif scour susceptibility, and also bridges having hydraulic deficiencies. Bridges identified as being scour-susceptible in Phase I were subjected to a Phase II evaluation, typically involving hydraulic modeling and calculation of potential scour depths in accordance with Federal Highway Administration guidelines. The Phase II program addressed both riverine and tidally-influenced bridges and bridges with unknown foundations. Hydraulics, scour and related information produced by the project was placed in a database and integrated into the States Bridge Management System.
