Let's do a quick
conservative calculation, as this is my job I do this all day long:
A. Miami beach sand need (3 miles long x 150 yards wide actual need will be a lot more):
15,840 feet long x 3 feet deep x 450 feet wide = 21,384,000 cf =792,000 cy.
B. Haitians filling 5 trucks 9 cy yard(standard) capacity daily:
Total for one day: 5 trucks x 9 cy = 45 yards/day
C. Time to meet demand: 792,000/45 = 17,600 days = 48 years
Like I said before, I doubt what these guys can get from these sand banks will be economically worth it. One must realize that this amount of sound being removed from the move of rivers will not be conspicuous.
