Numerical Modeling Studies Supporting Port of Anchorage Deepening and Expansion: Part I; Physical Setting and Dredging Issues
The US Army Engineer Alaska District is currently assessing hydrodynamic and port sedimentation issues associated with proposed expansion and deepening of Port of Anchorage, Alaska. The Port of Anchorage (POA) is located in lower Knik Arm, a macrotidal subestuary of Cook Inlet, characterized by large, seasonally variant suspended sediment loads; strong tidal currents; dynamic eddy structure associated with headland points and shoals, and expansive intertidal mudflats. Given the energetic conditions, large sediment load, and proximity to eddies, POA has recently experienced high sedimentation rates. Sedimentation rates at POA vary on seasonal and interannual to decadal scales. The interannual variability and remote proximity of POA to dredging resources make planning and scheduling of dredging resources complex and crucial towards successful execution of the USACE navigation mission. To anticipate sedimentation rates under proposed expansion and deepening of the port and to better accomplish the USACE navigation mission, numerical and physical modeling studies were performed.
