Description:
A device for the partial removal of erosion products in stormwater runoff has been developed. The swirl concentrator as an erosion control device has been designed to concentrate the heavier soils from large flows. The concentrated underflow of up to 14 percent of the flow can be directed to a forebay or settling basin. The device is circular and for small watersheds a simple stock watering tank could be used with only minor modifications. The design of the swirl concentrator as an erosion control device is based upon a hydraulic model study and research previously sponsored by the City of Lancaster, Pennsylvania and the U.S. Environmental Protection Agency into the mechanics of secondary motion flow-fields as developed in the swirl concentrator. This report is submitted by the American Public Works Association in partial fulfillment of the contract 68-03-0272 between USEPA and APWA Research Foundation.
