Well, that would require JSBSim to maintain a database for the physical properties (friction, etc.) of the terrain underneath the aircraft. I don't consider that to be something that the FDM should account for. That sounds like something that is in the domain of FlightGear or SimGear. However, JSBSim can expose via properties the friction coefficients that could be changed to reflect the type of terrain. For modeling landing on water OR land, that might be a little bit harder to model.
