Sedimentation Analysis
Started: 2nd
Quarter 2005

Brief description:
The sedimentation
analysis is an engineering effort that will determine the effect of the
proposed channel deepening on
maintenance dredging volumes, shoal locations, present advance
maintenance
locations, berth maintenance practices, and bank erosion potential. The scope of the study will cover both the
entrance channel and the
The effect of the
proposed deepening on the shoaling volume may directly affect the
maintenance
costs due to potential changes in the quantity dredged.
The shoal locations may affect the channel
maintenance costs by increasing or decreasing the pumping distance to
disposal
areas, thereby increasing or decreasing the unit dredging cost. Shoal locations may affect the channel
maintenance operational plan by having to shift the location of advance
maintenance areas to account for new shoal locations.
Berth areas will be examined for
potential changes in shoaling. Data from
this analysis
will be used to modify (if necessary) the existing Dredged Material
Management
Plan.
