| RE: <nettime> Whose Planning and on whose behalf and the slums that save us! |
Salutes, To explain the some little portion of the causes of dramatic looses in New Orleans I remind the basic rainflow formula as: F = CIA where, F: Flowrate in volume/time (The killing factor in a storm) C: Coefficient of permeability of ground I: Intensity of rain A: Area of the receiving basin C value is the ground permeability. Soil, sand, grass (natural) landshave smaller C values than concrete, asphalt (artificial) lands. As Mr. Benjamin said "USA is world's most developed nation"; that is the C value in New Orleans is greater than Mumbai; and approaches to maximum and causing all water, flow on the ground rather than infiltrate down. That may be a little reason of the harm. Thus, C: Coefficient of development (or directly "coefficient of storm harm") In developed cities, "storm water collection systems" are utilized to substitude natural infiltration process, in a limited capacity. The earth is said to be a big wetland (at least tends to be), And artifical measures cannot stop mother earth's tendencies. Surely, all these cannot explain violences, army action etc...
