You could use the deformation tab in the material. It does mean you have to subdmesh the plane (the material has settings for that so you don't have to deal with all those dense polys in the viewport - the submeshing only happens at render time).
Depending on your textures you may have to blur them slightly so that you get a nice rounded "bump". Go easy on the settings - depending on your scene scale it only takes a few digits to get a good deformation.
Depending on lighting bumps can work, but usually deformations (if you can afford the render hit) look better.
You can also use the deformation effector in Mograph or the deformation deformer to "bake" the polys into a mesh and save that out as an object. You can also just bake the texture and the deformation into the object with texture baking and then the system reads that cache at each render and saves the deformation time. This approach works great if the shadows aren't changing over time or for a still.
