| Abstract | This report presents the results of a research conducted in a hydraulic flume to determine the stability of rock riprap protecting abutments located on flood plains. The observed vulnerable zone for rock riprap failure is presented for two abutment types: vertical wall and spill-through (H:V = 2:1). Equations and velocity multipliers to assist an engineer in determining the stable rock riprap size are presented in this report for the two abutment types. Conditions found to influence the stability of rock riprap are also presented. The results obtained in this research report have been published in FHWA Publication HEC No. 18, "Evaluating Scour at Bridges," dated February 1991. |
