Scour Analysis at Missouri Bridges

In the late 1990s Missouri Department of Transportation (MoDOT) had a consultant perform a scour analysis on a number of bridges that had a high potential of being “scour critical” using Water-Surface PROfile (WSPRO) modeling to determine the hydraulic data. MoDOT would like to have a sampling of these bridges re-studied to evaluate the validity of the original scour analysis. The main objectives of the project are as follows: provide a methodology used to determine soil/rock sampling locations and depths, and the soil sampling and testing methods used; do a comparison of the scour analysis results using HEC-RAS (1D) hydraulic modeling data to results using SMS/SHR-2D hydraulic modeling data using the sampling methodology employed for this study; do a comparison of the scour analysis developed in second objective to the current analysis method of using a single soil sample from the stream bed, and to the existing scour analysis results developed using WSPRO hydraulic model data; and do a risk assessment, due to scour, for the bridges studied by the project.
