Western Hydraulic Engineers Conference - Presenter Bio/Abstract

Presenter: D. Max Sheppard, Ph.D.

Title: "A Methodology for Predicting Design Pier Scour Depths"

Abstract: A methodology for predicting design scour depths at bridge piers with and without physical model test results will be discussed. The predictive equations used in this analysis will be discussed along with laboratory clearwater and live bed scour test results. A new approach for obtaining scour depths at prototype structures from scale model tests will also be discussed.
