A scour platform to prevent scour of a moving body of water is constructed by
placing
an excavation adjacent to the body of water. The excavation is spaced laterally
from the body of water and extends up or downstream a desired length. A stabilizing
sheet material covers the bottom of the excavation. Aggregate is placed within
the excavation over the sheet material, and a free end of the sheet material is
then folded back over the upper surface of the emplaced aggregate. Any remaining
gaps between the excavation and the sheet material may be backfilled and compacted
as necessary. The scour platform is completed once the free end of the sheet material
is folded back over the aggregate. For additional prevention of scour, micropiles
may be emplaced between the scour platform and the body of water.
