Coastal restoration is a critical process for industries, municipalities and property owners who depend on healthy, functional coastlines and waterways. Understanding its importance along with coastal restoration techniques is key to maintaining operational efficiency, regulatory compliance and long-term site resilience, whether you manage a marina, operate a wastewater treatment plant or oversee an industrial lagoon.
Coastal Restoration Definition
Coastal restoration goes beyond repairing shorelines. These practices focus on rebuilding the natural and engineered systems that protect and sustain coastal communities and industries, allowing them to thrive.
Restoration involves rebuilding or rehabilitating coastal habitats and functions that have been lost or degraded due to natural or human causes. Degradation can be caused by various influences, including:
- Natural erosion from waves, currents and storms.
- Storm damage, including hurricanes and flooding.
- Human impacts like industrial runoff, dredging and infrastructure development.
- Altered water flows.
The goal of restoration is to restore ecological balance, protect infrastructure and ensure the continued use of waterways.
The Critical Importance of Coastal Restoration
Restoring coastal environments is a strategic investment in economic stability, operational continuity and environmental health for businesses and communities. A great deal depends on getting it right.
Economic Stability
The marine economy accounted for $511 billion of U.S. gross domestic product in 2023, with estuaries supporting 59 million jobs.
Coastal restoration plays a vital role in shielding coastal communities, ports and industrial facilities from the damaging effects of erosion and storm surges. By reinforcing shorelines and restoring natural barriers, restoration efforts help reduce property damage and lower insurance costs for businesses and municipalities alike.
Additionally, healthy coastlines support local economies that depend on tourism, shipping and recreation, ensuring these industries can continue to thrive without the constant threat of environmental degradation.
Operational Continuity
For marinas, ports and shipping channels, maintaining navigable waterways is essential to daily operations and long-term viability. Coastal restoration and the use of dredging in waterway management mean these critical routes stay open and functional, preventing sediment buildup that can impede vessel movement and disrupt commerce.
Restoration also supports the proper function of settling ponds, lagoons and other industrial water systems, which are vital for wastewater treatment and process water management. By proactively addressing sediment and erosion issues, organizations can minimize costly downtime and avoid emergency repairs that disrupt operations and strain budgets.
Environmental Health
Restoring coastal environments leads to significant improvements in water quality by reducing the amount of sediment and contaminants entering waterways. The benefits of coastal ecosystem restoration include rebuilding habitats for fish, birds, and other wildlife, supporting biodiversity and ecosystem resilience.
With more than 40% of Americans living in coastal regions, effective restoration helps industrial sites meet increasingly stringent regulatory requirements for water discharge and habitat protection, ensuring compliance while contributing to the overall health of the environment.
A Guide to Coastal Restoration Techniques
There are several approaches to coastal restoration, each suited to different site conditions and operational goals. Understanding these techniques helps you choose the most effective solution for your unique challenges.
Nature-Based Shoreline Stabilization
Nature-based shoreline stabilization is an increasingly popular approach in coastal restoration. It focuses on the use of natural materials and ecological processes to protect and rebuild vulnerable shorelines. Unlike traditional hard structures, these methods work with the environment to create resilient, self-sustaining barriers that can adapt to changing conditions.
Using natural materials and vegetation, like mangroves, salt marsh grasses or oyster reefs, can help stabilize banks and absorb wave energy. According to the National Oceanic and Atmospheric Administration (NOAA), dredged sediments from the navigation channel between Swan and Smith Islands in Chesapeake Bay are expected to enhance Swan Island ecosystems, increase the island’s resilience to sea level rise and reduce erosion impacts for the nearby town of Ewell, Maryland.
The following are key benefits of coastal ecosystem restoration:
- Enhanced habitats
- Filtered pollutants
- Long-term resilience
Structural and Replenishment Methods
Structural and replenishment methods are well-established techniques in coastal restoration, often used to give immediate and visible protection for vulnerable shorelines. These approaches rely on engineered solutions and the addition of new materials to stabilize coastlines, restore eroded areas and defend against the forces of waves and currents.
Traditional structures include breakwaters, jetties and seawalls that protect shorelines from wave action and erosion. Teams can add sand or sediment to eroded beaches to restore width and elevation for beach nourishment.
Some key considerations for structural and replenishment methods include:
- Cost.
- Ongoing maintenance needs.
- Underlying sediment or containment issues.
Advanced Sediment Removal and Dewatering
Advanced sediment removal and dewatering techniques are essential for commercial and municipal sites where accumulated or contaminated sediment can disrupt operations and threaten compliance. By leveraging specialized equipment and engineered containment systems, these methods offer a practical, efficient and environmentally responsible solution for restoring the function and safety of critical water bodies.
For many industrial and municipal sites, restoration begins with the critical task of removing accumulated or contaminated sediment that can hinder daily operations and jeopardize compliance. Over time, sediment buildup in lagoons, ponds and waterways can reduce water capacity, block flow and introduce pollutants that threaten infrastructure and the surrounding environment.
Addressing these issues at the outset is essential to restoring full functionality, maintaining safe and efficient processes and meeting the strict environmental standards required by local, state and federal agencies. By prioritizing sediment removal, organizations lay the groundwork for successful, long-lasting coastal restoration.
Dredging
Dredging is a versatile process used in a variety of coastal and inland water management projects, each with its own specific goals and challenges. Understanding the different types of dredging projects can help site managers and engineers select the most effective approach for their operational needs:
- Maintenance dredging removes accumulated sediments to keep existing waterways, harbors and lagoons at their designed depths for safe navigation and uninterrupted operations.
- Remediation dredging targets the removal of contaminated sediments from water bodies, helping to restore environmental health and meet regulatory standards for water quality and habitat protection.
- Water deepening involves dredging to increase the depth of channels, ports or basins, allowing larger vessels to access these areas and supporting economic growth through improved transportation routes.
- Offshore dredging is carried out in deeper, open-water environments, often to extract sand or other materials for beach nourishment, land reclamation or construction projects.
- Material or mineral dredging is used to recover valuable materials like sand, gravel or minerals from underwater deposits, supporting construction, manufacturing and resource extraction industries.
- Waterway construction creates new channels, basins or harbors in the development of new infrastructure and expanding access for commercial and recreational activities.
Coastal Restoration Process Overview
The advanced sediment removal and dewatering process is designed to manage sediment buildup while minimizing disruptions to ongoing operations. This multistep approach uses specialized equipment and containment systems to ensure sediment is safely removed, processed and managed responsibly.
Here’s how the process typically unfolds:
- Sediment is extracted from lagoons, ponds or waterways using powerful pumps and dredging equipment, allowing for precise and efficient removal even in challenging environments.
- The sediment-laden water is then pumped into high-strength geotextile tubes, which act as secure containment vessels for the dredged material.
- As the mixture settles inside the geotextile tubes, water filters out through the fabric, leaving behind dry, consolidated solids that are much easier to handle and transport.
- Once dewatered, the dried solids can be safely transported offsite for disposal or repurposed for beneficial uses like building berms, fill material or landscaping projects.
By securely containing dredged material, these methods prevent recontamination and help sites meet regulatory standards. Additionally, the approach is highly scalable, making it suitable for projects ranging from small ponds to large industrial lagoons.
