A Methodological Framework for the Economic Analysis of Curtain Barrier Sedimentation Control Systems,
Abstract
One promising concept that is currently being examined for reducing sediment accumulation in enclosed, quiet-water berths is passive denial by use of curtain barriers. In its most simplistic form, a sediment-impermeable membrane is placed across the entrance to the berthing area, thus forcing sediment-ladened water to remain in the channel/harbor area and denying it access to the quiet-water berth. Although individual designs may differ in implementation details, e.g., full height vs partial height, methods for opening and closing to permit ship access, etc., the basic notion is still the same. Given that the engineering details for a given application site can be resolved (not always a trivial matter), there appears to be a need to be able to determine, from an economic basis, which particular sites offer the greatest potential and which do not appear promising from economic consideration. In short, there is a need for an economic screening method that can be used to determine potential application sites for curtain barriers at Navy berths. This report presents such an economic screening method, identifying those variables to which decisions are most sensitive, and illustrates the use of the method by applying it to selected naval berthing areas.
