Riprap Size Selection at Wing-Wall Abutments

This note reports results of an experimental investigation of riprap stability at wing-wall abutments. The aim of the experiments was to determine the size of riprap stones necessary to resist shear failure by the flow. The results, obtained under a wide range of mobile-bed conditions, are compared with predictions of riprap stone size given by existing equations. Two existing methods, with the addition of suitable factors of safety, are shown to give stable stone size for riprap layers at wing-wall abutments under mobile-bed conditions. It is noted that consideration needs also to be given to filter protection, edge effects, and the effects of bed-form undermining in the design of such riprap layers.
