Tigris and Euphrat on your map do not have any common source. So they do not correspond to the Genesis description at all.
You say that it just changed. Is there any evidence of such huge change?
And even if some river dries up, there is still detectable river bad, at least on satellite maps. If it went around all Ethiopia, it had to be a large river (Ethiopia is below Egypt).

Maybe this site will help in your search, but I reckon it will still be only theoritical and hard to prove, but you may find it interesting.
The Rivers of the Garden of Eden
First, let's identify the geographical region of the Pison river. The Bible says: "Pison: that is it which compasseth the whole land of Havilah, where there is gold" and gives us two good clues. There is a recently discovered "Fossil River" that runs from the western mountains of Saudi Arabia towards Kuwait. This old river course is now nothing more than a dry riverbed. It was detected by satellite imaging. Many have speculated that this may be the ancient Pison, as it has been dry since about 3,500 to 2,000 BC. Although Saudi Arabia could marginally qualify for the land of Havilah, the fossil riverbed that flows across it had its origins in the mountains bordering the eastern side of the present day Red Sea, south of Israel.
