In 1987, the US Army Engineer District, Portland, sponsored an innovative dredging operation to remove sand waves from a portion of the Columbia River navigation channel. Sand wave development and crest protrusion into the navigation channel along the Columbia River is a routine maintenance problem for the Portland District. Sand wave removal with conventional dredging equipment is effective, but often inefficient. A jet fluidizer dredge plant, designed and constructed by Western Pacific Dredging Company, was selected for this exercise. It operated on the concept of hydraulically leveling sand wave crest material into adjacent below-project depth trough sections. This report evaluates the jet fluidizer field performance.
