Improved Calculation of Scour Potential in Cohesive Soils and Scour Susceptible Rock

Scour in cohesive soils and rock has been a challenge for engineers in development to design safe, yet cost-effective new bridges with these site characteristics. Also, many existing bridges have been identified with a scour critical condition, this poses safety risks and requires additional resources for inspections. Unlike non-cohesive soils, standardized scour analysis methodologies and broadly accepted guidance on testing and then subsequent analysis of the scour susceptibility of cohesive soils and rock are lacking. Nationally, research has been conducted by various states and educational institutions related to this topic, however this has not been accomplished within Michigan’s unique environment at MDOT bridge sites.
