Improvement of Operations and Maintenance Techniques Research Program. Evaluation of an Experimental Jet Fluidizer for Removal of Sand Waves in the Columbia River. Report 2. 1988 Exercise
Abstract
An experimental jet fluidizer for the removal of sand waves in the Columbia River navigation channel. The performance of this jet fluidizer is being evaluated and reported on in a series of reports. Report 1 of this series presents design details and results of the first dredging exercise that took place September-October 1987. Although the fluidizer proved successful at removing the specified sand wave volumes, recommendations were made for improving the fluidizer efficiency and reducing the unit cost per cubic yard of material removed. This report describes the modifications that were made to the fluidizer dredge and evaluates the field performance for the second dredging exercise that took place September-October 1988.
