An analytical method for estimating return velocity and drawdown is developed based on physical model study data for the Kampsville reach, Illinois River and the Clark's Ferry reach, Mississippi River. The analytical method uses conservation of energy plus empiricism to define the distribution of maximum return velocity and maximum drawdown during the tow event. The method is compared to prototype return velocity and drawdown data from two sites on the Illinois River, two on the Mississippi River, and four on the Ohio River.
