Improving and maintaining navigation harbors and channels is one of the key functions of the US Army Corps of Engineers. The present cost-sharing system and the increasing costs associated with dredging operations require more efficient utilization and development of existing and planned navigation channels to keep the Nation's ports competitive. Advance maintenance dredging has become common practice at critical shoaling areas of many Corps-maintained navigation projects to extend the time between required dredging operations. This paper presents the application of numerical hydrodynamic and sediment transport modeling to assess advance maintenance dredging performance.
