Waves generated by a source below a free surface in water of finite depth

The free-surface flow due to a submerged source in water of finite depth is considered. The fluid is assumed to be inviscid and incompressible. The problem is solved numerically by using a boundary integral equation formulation due to Hocking and Forbes 6]. The numerical results show that there is a train of waves on the free surface in accordance with the results of Mekias and Vanden-Broeck 5]. For small values of the Froude number, the amplitude of the waves is so small that the free surface is essentially flat in the far field. These waveless profiles agree with the calculations of Hocking and Forbes 6].
