Okay. So when I was calculating how many Amazons were needed the perimeter didn’t matter, and the answer was just 3. But when you asked how many litres would be pouring over each meter of perimeter I did the calculation based on the idea that an equal amount of water was passing over each bit of the perimeter.
Otherwise the answer is of course that the water forms together into rivers so that most of the perimeter has no water passing over it but the mouths of the rivers have a great deal of water passing over them.
