Let Flood Water Clear Itself : Our Humble Solution

For the increasing of carrying capacity by 2 times during high downpour or ocean water entering city, Toms’s effect is applied. Effect states: if we’ll add a micro-quantity of polymer (polyacrylamide, for instance),  than slipperiness of water increases several times. It is enough to add 0,01% of polymer, i.e. no more than 100 milligram/liter of water to increase slipperiness by two times. 

How should the polymer  be added? Who will add this substance in disaster? Here is the needed ideal solution. Water must itself adding the polymer. Let’s formulate more precisely 

«Over limiting» water adds polymer at high downpour and «usual» water during normal rain does not add polymer. 

A well is made in which a small bag containing polymer is dropped. In flooding, water fills the well, dissolves the polymer in itself and overflows. Overflowing water now carrying polymer is slipperier and drains fast in city's severs or other through other equipment brought to pump out water. 

As usual, high level inventive solutions carry add-on advantages further magnifying Idealization achieved from idling or low-cost solutions. Here an idle resource (flood water) with a slight modification (polymer) clears flood water itself! 

1) Increasing of water’s slipperiness is  discrete and self-controlled.. After contact of polymer, 

flood water recedes.  Further contact with polymer ceases. This is also a reason for very small amount of polymer to be needed.. 

2) This polymer also helps in quicker sedimentation and hence clearing heaps of rubbish that float during floods and later turn a nuisance to clear.
