As for geokinesis... Firstly, Percy doesn't have much control over that ability, and even if he did, it doesn't significantly impact Jason if the latter chooses to fly up high into the air. To the best of my knowledge, he has not once tried to generate pure water (the only time that I can recall that fresh water is mentioned is during The Last Olympian, in which he uses a sand dollar to purify the Hudson), so unless you are privy to some knowledge that none of us are aware of, we don't know that. Also, appearance and reality are two separate things; without a doubt powerful gusts of wind take a toll on Jason to some degree (he may or may not show it and Riordan may have neglected to mention it altogether). To add to that, conversely, it doesn't appear that channelling the power of the sea, when next to even the smallest body of water, is exhausting to Percy. However, I digress.

As for a combat zone, I highly doubt that either of them are stupid enough to challenge the other on their terms in terms of terrain. So for the sake of this discussion, we can assume that the battlefield is an open plain during a summer day.
