International Dredging Review

International Dredging Review
MENUMENU

The U.S. Army Corps of Engineers Baltimore District, the Maryland Department of Natural Resources and Worcester County signed a Project Partnership Agreement to start work on a navigation improvement project to address sediment accumulation, within the Ocean City Inlet.

The Corps dredges the inlet two or more times per year to maintain the channel’s authorized depth of 10 feet. Through the Ocean City Harbor and Inlet navigation project, the Corps will evaluate sediment transport in the inlet and recommend options for addressing the shoaling to include structural solutions like jetties or channel modifications like deepening the channel in the inlet.

The Corps and its partners are planning to host an open house and public meeting in early spring to provide further details and obtain feedback from the community and stakeholders on this effort, as well as a separate, concurrent study to address a large scour hole that has developed just northwest of the inlet near Homer Gudelsky Park.

As part of the federally funded Scour Hole: Beneficial Use of Dredged Material study, the Corps and crews from the Corps Engineer Research and Development Center began gathering field data in 2017 to better understand the scour hole, including collecting sediment samples, deploying instrument suites, and mapping the region to obtain information about the movement of sediment in and around the scour hole. In 2019, the team plans to use this data to begin modelling potential alternatives for addressing the scour hole.

The team is considering the beneficial reuse of material dredged from Ocean City Inlet as part of navigation improvements. Beneficial reuse could include anything from ecosystem restoration, such as restoring islands for bird habitat to potentially providing material to fill the scour hole before a long-term solution is implemented.

Both efforts are being conducted through the Corps Continuing Authorities Program, which allows the Corps to partner with state and local partners for smaller water resources issues without the need for Congressional authorization. If projects through this program are found to be in the federal interest, they can proceed with implementation, pending additional funding
