One of the Corps of Engineers responsibilities is that of improving and maintaining navigation channels and harbors. In recent years, the cost of maintenance dredging in estuaries has grown rapidly because of such factors as increased environmental awareness, diminishing availability of cost-efficient disposal sites, and rising labor and dredging plant costs. In view of these continually rising maintenance dredging costs, any equipment, operation procedures, or methodology that enhances the cost-effectiveness of dredging should be utilized to full advantage. Advance maintenance dredging is a practice in which the channel reach is deepened or sometimes widened to allow a reduced dredging frequency or to improve project quality. Project quality refers to the percent of time in which a navigation channel remains at project dimensions between dredging activity.
