Summary An obstacle, represented by a delta function, is placed on the bed of a three dimensional stream and, as a result, a steady “V” shaped surface wave pattern develops downstream. The rate of decay of the transient motion is determined and existence and uniqueness of the steady pattern are established for all values of the stream velocity. Asymptotic expressions for the steady state wave amplitude, valid far from the obstacle, are obtained. Near the border of the wave pattern, expressions are obtained which are uniform in the polar angle.
