Answer by Ray K
As a river increases in size, the problems associated with diversion increase exponentially. While we were able to bore/drill two diversion tunnels through solid rock, the extreme size of the Yangtze requires tunnels at least 5 times(?) larger or more in number. (As you double the cross sectional area of the tunnel, you should be able to pass 4 X the volume).
