Coastal Engineering Design for Coastal/Civil Infrastructure

Woods Hole Group bases coastal engineering design on developing a solid understanding of site-specific coastal processes. As such, engineering design extends beyond just calculations and drawing - designs are geared to work effectively with the coastal processes to identify the most feasible solution, while extending the system service life. All stages of alternative assessment, design, and planning coastal infrastructure rely on years of expert experience from a group of personnel who have made understanding oceans, coasts, harbors, and estuaries their engineering focus. This expertise provides added value to the coastal engineering design process and ensures that the solution is site-specific and attains the desired goals. Specific capabilities include:

  • Alternatives Analyses
  • Design Parameter Development
  • Project Planning & Design
    • Beach Nourishment & Offshore Sand Mining
    • Dredging
    • Coastal Structures
    • Soft Solutions for Shoreline/Bank Stabilization
    • Port and Waterfront Marine Infrastructure

Engineering Alternatives for Climate Change


Woods Hole Group worked with a diverse project team on assessing the physical and economic impacts of Climate Change on coastal communities of Groton, Connecticut. The evaluation included the impacts of sea level rise and storm events on potential flooding.

Local stakeholders were integrated into the discussion through a series of community Coastal Climate Adaptation Workshops that brought together federal, state, and local stakeholders to begin addressing the question: "how do we collaborate across geo-political boundaries to prepare for climate change impacts?" The workshops provided an overview of regional climate impacts, explored how federal, state, and local governments are vulnerable to changes in climate, particularly sea level rise, and included consideration of potential adaptation actions to increase resilience, and identified strategies for implementing adaptation actions across geo-political boundaries.

For each community, conceptual designs of engineering adaptation alternatives were developed. The alternatives ranged from management approaches (evacuation, flood-proofing of structures, etc.), soft-engineering options (e.g., beach nourishment, creation of wetlands, etc.), and more significant hard engineering structures (e.g., modular seawalls, revetments, tide gates, hurricane barriers, etc.). The community recommended alternatives for which cost estimates were determined. Engineering adaptations and costs estimates were provided for high and low rates of projected sea level rise, coupled with various return period storm events (10-, 20-, 50-, and 100-year) projected to the year 2070.

Regional Dredging and Beach Nourishment


The Edgartown project on Martha's Vineyard is an example of a successful private/municipal partnership, where vital private funding revived the Town's dredging and beach nourishment program to restore local beaches. The project was designed to beneficially reuse dredged sediments from local navigational projects to provide safe boating in navigable waterways within the Town and to restore both public and private beaches by using navigation dredge sediments for nourishment.

Woods Hole Group was tasked with the dredging and beach nourishment planning, design, permitting and oversight of the project. Phase I of the Beach and Dune Restoration project was initiated in October of 2009 and included dredging, dewatering, barging, trucking and grading of 30,000 cubic yards of sand. The beach compatible sand was placed along a 3,140-foot stretch of shoreline to reconstruct the almost non-existent dunes on the public Bend in the Road and private Cow Bay Beaches.

During the summer of 2010, the neighboring Town of Oak Bluffs joined the municipal/private partnership with the Town of Edgartown and the Cow Bay Corp. The partnership expedited Phase II of the project by allowing use of a combination of dredged sand from both towns and upland sand barged from off-Island to meet the design template. Construction commenced in October of 2010 and the 100,000 cubic yard regional beach nourishment project was finished in March 2011

The design, permitting and coordination of this project were extremely complex, but the results greatly benefited storm protection, recreation, and wildlife habitat. The project won the Best Restored Beach award from the American Shore & Beach Preservation Association (ASBPA).
