I am doing a project for school and I was wondering if you could answer my
question. What can be done to reduce the amount of flood damage? Thanks.
Invent dry water.
Wolfgang
The precise term is dehydrated water, Wolfgang.
Bill
Actually there is a difference between dry water and dehydrated water.
Dehydrated water is made by removing the moisture from regular water,
while dry water is a man-made chemical that becomes water with the
addition of a suitable wetting agent.

And don't forget about heavy water (one extra electron, or was it
neutron?,
per molecule, if I remember my chemistry, and I may not). All other
things
being the same, if the flood must occur with wet water, is it any worse
if it occurs with heavy wet water?

Clearly what we need is a generic water encapsulation technique that would
allow the wet water to pass through a tunnel without leaking into the
surrounding domain.
This encapsulation technique results in a design that might be called a
"storm drain system" which, together with a proper sewage drain system, we
could call a "SIN mode" drainage system.
We could also multiplex the rain water with the sewage water in a
multi-mode drain system. Internet drain specialists tend to take religious
points of view on whether we should have separate drain systems, should
combine them, or outlaw one in favor of the other. But, clearly,
encapsulation is the favored approach.

The multiplexed drain system will never work. Sewage water we know
to be a fairly constant flow over time, and in fact sanitary engineers
refer to it as having a Constant Flow Rate. Storm water, on the other
hand, is
very bursty in nature, and sanitary engineers describe that as Variable
Flow Rate. In the old days they tried combining drain systems, sharing
the resources between the CFR water and the VFR water, and called the
result AFR (or
available flow rate). AFR had one weakness, however: it relied upon a
phenomena called precipitation shaping to keep the VFR storm water from
interfering with the CFR sewage water. As the clouds and the ground
didn't
have enough buffering to do proper precipitation shaping, the result was
a drain system which periodically suffered massive congestion, and all
users were equally unhappy.
