Shoreline Protection & Bank Stabilization
Coastal Restoration and Protection efforts are critical to the survival of many coastal communities across the United States and the world. With limited funding and large areas to restore & protect, it is a struggle to find cost-effective methods that are sustainable over time. The BioHaven® Floating Breakwater (BFB) and EcoShield™ makes protecting and restoring disappearing coastlines more attainable than ever before.
By mimicking natural marsh and the naturally occurring processes of coastal ecosystems, the BFB essentially creates new marsh. It floats much like flotant marsh and can adjust with the rise and fall of water levels and tides. The characteristic of floatation all but negates concerns of sinking and settlement for project planning as exists with other technologies being used today.
BFB’s act as a wave breaker reducing wave energies on shorelines in open bays, lakes, and bayous. When placed along a shoreline, BFBs can be used in lakes affected by recreational boat activity as well as fragile coastal habitats impacted by waves. A recent study conducted by the University of South Alabama suggests that the BFB is very effective at attenuating waves such as wind chop.
Surviving the Storm
BioHaven® Floating Breakwaters have survived hurricane force winds of at least 90 miles per hour and a 5 foot storm surge as was the case during Hurricane Isaac in 2012. While the vegetation appears windblown, the BFB remained anchored in place.
BFBs are manufactured with an engineered bushing for secure anchor point connection. Martin Ecosystems recommends anchoring the BFB with helical anchors.
Floating on top of the water, BioHaven® Floating Breakwaters provide a beautiful habitat for waterfowl and wildlife. Below the surface, suspended roots provide shelter for fish and aquatic life while also working as a filter to remove unwanted nutrients from the water body.
View the case study demonstrating how BFB’s are creating new marsh and protecting the shoreline in the award winning Isle de Jean Charles Project in Pointe-aux-Chene, Louisiana. The Isle de Jean Charles project along with our project partner, Shell Oil was awarded the 2013 EPA/Gulf Guardian Award and was 1 0f 3 finalists for the 2014 World Petroleum Congress World Excellence Award.
Vegetated EcoShield™ is one of the most environmentally efficient products to protect existing shorelines, levees, berms and terraces, while also promoting vegetative growth and creating a “living shoreline”. Vegetated EcoShield™ combines base matrix layers of proud recycled PET plastic with pre-vegetated matrix strips. The pre-vegetated matrix strips are installed at mean tide, providing immediate protection from war energies while allowing for plant establishment, root growth and ultimately lateral spread.
The system is designed to reduce wave energies and extend the life of levee systems, berms and terraces.
