Weakly nonlinear long waves generated by topography in a uniform flow of two-layer fluid in which one layer has infinite depth are considered. They are described by a forced Benjamin-Ono (fBO) equation when the linear wave speed is close to the uniform flow speed. Generation and propagation of waves are investigated by solving the fBO equation numerically for various flow speed and topography. Approximate analysis is possible for the topography with very small (or large) steepness. Its results are compared with the numerical results.
