Finite-amplitude internal waves resonantly excited by three-dimensional topography in the flow of a weakly and nearly uniformly stratified fluid are studied. This flow is mainly governed by a stratification profile and the Froude number. The numerical solutions of Navier-Stokes equations show various wave patterns, such as the Mach reflection and upstream propagation of solitary waves, depending on the values of these parameters. A comparison with solutions of fully nonlinear model equation is also made.
