i have a question about  how does the land that's under water make it to the top and water fades ? i mean take a little lake and then the water naturaly evaporates more less but how does that happens in here ? is there someone working on it or it's done automatically here ? i see some little rocky islands coming out of the water bottom floor into the surface ! so is this done by someone or it's programmed to do so originally ? thanx to all for reply !

Right now the water is simply everywhere where the elevation is below the mean sea level. So, if the land around the Caspian sea is around -28 meters below the mean global sea level, in OT it will be all underwater up to 0 meters height, because there's simply an implicit sea surface at 0 meters. It isn't being simulated - i.e there's no vapor loss and water flow computed, so no matter how small a lake would be encircled by land, it won't evaporate by itself. Rocky islands are just placed procedurally into shallow sea areas.

The simulation would be too expensive and due to various errors it even could not get to the same state as the reality. What we are going to do instead is basically applying polygon patches that artificially lower or raise the water level, creating dried land depressions under the mean sea level and lakes, respectively.
