Let's see. Since the max ordinate for the dam in terms of upstream fill
is
supposed to be only about 175 meters, from what I have read, you halfway
dimension would apparently be, based upon that 122 meter estimate above,
something like 57 meters--let's be generous and assume a more favorable
number for you, of maybe 40 meters (reflecting a more realistic actual
cross
section). Which last I knew was quite a bit more than 100 feet--more
like
125 feet?

125 feet? Heck, if you can deliver them accurately a handful of GBU-28s
should take care of the problem. Granted, the hole wouldn't start out that
big between the water pressure and the fracturing around the hole I expect
that problem would get bigger quickly enough.
Now, could Taiwan deliver them (or a local equivalent), that could well
be an issue.

First, Taiwan has no -28 delivery capability; the USAF limits such weapons
to deployment on B-2's and F-15E's, IIRC. Secondly, GBU-28 penetration in
concrete is about 20 feet from what I have read (the over 100 feet number is
an earthen penetration. So don't be expectin' to punch many neat little
holes with it in such a structure.
