Abstract:This research developed an improved method for optimizing the disposal of dredged material
at offshore disposal sites. A nonlinear programming model has been developed to assist in
the development of dredging plans at open water disposal sites. The model has been
developed based on conditions at the near-shore open water disposal site near the mouth of
the Columbia River. The optimization model considers available capacity of cells within the
disposal area to produce a dredging plan that minimizes mounding within the site.
Ultimately, the optimal dumping plans will be loaded in the MDFATE computer program to
simulate various stages of the dredging disposal cycle. Initial testing of the optimization
model indicates that it produces reasonable dumping plans.
