Tunnel under the Chao Phraya is worth considering
Play
Tunnelling has been suggested by some experts in Thailand as an absolute necessity for future flood control and flood prevention here, but modern high-rise buildings have pilings (foundations) so deep that they might preclude putting tunnels under a city
The exception to that, of course, is the Chao Phraya River itself. It would involve a massive undertaking, but a huge tunnel running deep under the Chao Phraya – a river-under-a-river that could be opened or closed, if desired – could conceivably double the current capacity of the river. As all viable ideas should be considered, this is one more to be considered.
