Here is an extremely good problem for supercomputer modelling of weather. In summary, the weather system is no problem to Designer Geography simply because the weather system is plastic and adaptable. That is a real problem and I am hoping that the supercomputer modelling will give some answers to this question line. To achieve maximum hydro electricity it is essential to have plenty of rain back unto the plateau lakes from the river oceans. Here we can look at present analogies.
Ocean is the closest ocean to that of a river.
How much rainfall does the Med. Look at Norway for another analogy. It is hard to tag a drop of rainwater and to tell where every Norway raindrop came from. It is questions like these that a supercomputer must help us in answering. When we finally decide on a Geography Design of the future, we shant make too many mistakes because it is costly to move things around.
