An unprotected cylindrical pier was exposed to the erosive forces of unidirectional currents with superimposed waves traveling with or against the current. The same set of tests was repeated with a cylinder through which ground flow was pumped. Inducing suction through a cylinder placed in a sand bed greatly reduces scour and enhances stability. By sufficiently increasing the pumping rate, even the combined dislocating forces of waves and currents can be nullified.
