Recent efforts are described to develop an improved understanding of bank failure due to piping in noncohesive layers in riverbanks. The efforts included field surveys and laboratory tests. The latter focussed on the relationship between pressure gradient and seepage rate in, and rate of erosion of, the noncohesive layer; and on the mode of bank failure.
