✦ Synopsis

A numerical method is presented for determining the shape of the free surface of a running stream which is disturbed by a semi-elliptical body affixed to the bottom. The effects of non-linearity on the wave resistance experienced by the semi-ellipse are discussed; most importantly, it is shown that there exist ellipses for which the non-linear wave drag is zero. Two wave-free (drag-free) surface profiles are presented.
