Flow impingement occurs when approach channels direct Oow into a bank line at large acute angles. Flow impingement results in flow concentration along bank lines, which creates large forces on bank material or bank protection. As part of studies conducted to determine tbe required riprap size for impinged flow, velocities, water-surface elevations, and scour depths were measured on the Snake River near Jackson, WY. High velocities and steep water-surface slopes were observed at each impingement site.
