Two concepts for reducing sedimentation in the turning basin at Mayport Naval Station were evaluated using a simplified box model methodology. The two concepts included a shallow venting canal and an extension to the entrance channel jetty. The simulation model predicted that an optimally-sized venting canal would reduce the rate of sedimentation in the turning basin by approximately 60. This result, however, was found to be particularly sensitive to uncertainties in the input data set. In constrast, the simulation model predicted that the proposed jetty extension would reduce the sedimentation rate by 85. This result was not as sensitive to the uncertainties in the data set. With the relative cost of the canal being approximately one-tenth that of the jetty extension, the higher degree of uncertainty associated with the canal is offset by significantly higher potential cost savings.
