From page 4...
... Research was needed to evaluate current methods for predicting local pier scour and their applicability to wide piers and long skewed piers and to develop improved methods for highway agencies to use in the design, operation, and maintenance of highway bridges. NCHRP Project 24-32 was initiated to address this need.

... Chapter 6 covers the predictive equations for scour at piers skewed to the flow. Chapter 7 summarizes the results of this project regarding the best equations/ methods for predicting equilibrium local scour depths and scour evolution rates for wide piers and long skewed piers and outlines recommendations for future research.
