| dc.description.abstract | The purpose of the project is to perform maintenance dredging within the federally authorized Anclote River Channel in order to maintain safe and efficient navigation. The need for the project is driven by the accumulation of sediment, commonly referred to as shoaling, which has restricted the width of portions of the channel and reduced the depth. Shoaling may arise from: (1) the natural, relatively slow processes of sediment movement along barrier islands and waterways resulting from tides, gravity, and wind; and (2) unpredictably and suddenly as a result of storms, especially hurricanes. Shoaling hinders safe and efficient vessel navigation. Thus, periodic maintenance dredging is required to remove the accumulated sediments and maintain the Anclote River Channel at its federally authorized depth and width. The Anclote River Channel was originally constructed in 1948, with 23,000 (23K) cubic yards (cy) of material dredged. In 1959 and 1960, 62K cy was dredged from the entrance channel. In 1973, 138K cy was dredged from Cuts 3 and 4, Cuts 6 to 14, and the turning basin. In 1999, 47K cy was dredged from the turning basin and Cuts 3 to 14 (Corps 2017a). The 2016 post-Hurricane Hermine hydrographic survey showed some shoaling through much of the channel, with a need for dredging in Cuts 3, 4, and 5 and the turning basin. Current dredge volume is estimated at 50 to 70K cy (Corps 2016a, #17-029; 2016b; 2018a), but is subject to change. Maintenance dredging is dependent upon federal appropriations. Maintenance dredging of the Anclote River channel will meet the Corps’ primary objective to maintain safe and efficient navigation through the channel. | en_US |
