The U.S. Army Corps of Engineers and its Engineer Research and Development Center are currently conducting R&D to operationalize technology that separates sand from mud while it’s being transported in the discharge pipeline of an operating hydraulic dredge. The enhanced placement method will eliminate, or significantly reduce, the subsequent re-handling of the sediment and often exorbitant associated costs of that process. These improvements will be based on two key Engineering With Nature® elements, using science and engineering to produce operational efficiencies and using natural processes to achieve maximum benefit.
