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

Invent dry water.
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. Jeremiah

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? -peter

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. --Kent

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. -peter

And so began the great "Asynchronous Torrent Mode" vs. "Practical Obviation of Storms and Intermitent Precipitation" debate... Alex Bligh Xara Networks
