ABSTRACT:
An erosion control system and method wherein a fabric filter bag is embedded with and/or filled with a flocculating polymer and is positioned on a sloping soil surface to dam and pond water flowing thereacross for settling of the particles in the water, and as the ponding water seeps into the bag the colloidal particles will be filtered or agglomerated for settling. The water then passes through and out of the bag and is further subjected to agglomeration and filtering by a skirt of filter material also impregnated with flocculating polymer, said skirt being anchored to the bag or stacked to maintain the position adjacent and downslope from the bag.
