Our Technology

The Beach Nourishment System (BRNS) is of "site-specific" design and engineered to use natural sea power to capture flowing sediment and deposit it on the beach. We call this erosion reversing method, understanding and use of technology “Accretion Engineering.”

How it works

The Beach Nourishment System (BRNS) is a series of “nourishment tubes” that diminish the energy of a wave and effectively reduces their ability to transport sediment, thus reconstituting beaches.

During more turbulent weather, storm energy produces a “renourishing” cycle by its ability to move offshore sediment into the near-shore system, allowing for its capture by the BRNS.

The Benefits of the BRNS Solution

In addition to being a scientifically proven technology for reversing beach erosion, the Beach Recovery Nourishment System also helps restore the natural dune development process, as well as recreates sustainable and healthy shoreline ecosystems common to pristine coastal environments.

By harnessing the awesome power of wave energy to recover sand thought to be “permanently lost” to the sea, BRNS is able to naturally re-establish coastline accretion cycles.

Sustainability, “Greenness”, and Permanence by Solving the Root Cause of Erosion

BRNS mimics the type of geology that causes natural beach profile elevation – “by fixing the ocean bottoms”– the beach returns to its natural state where sediment is deposited on the beach, not carried away.

The entire system is ultimately buried under the new sand accretion, providing a stable environment for plants and animals. People enjoying the beach will not even know it’s there. All they’ll see is a beautiful, soft-sand, natural beach.

Should a catastrophic event strike the beach in the future, such as a hurricane, the BRNS will be reactivated immediately to begin rebuilding depredated beaches.

 

 

Our engineers properly position “nourishment tubes” (BRNS) on the near shore
that mimic the type of geology that causes natural beach accretion. Water
flowing over the BRNS creates a vortex, reducing wave and current energy and
capturing the sand within the system (Figure 1).

Sand accretion on this type of “induced” profile is correctly sequenced with
respect to grain size distribution (because natural processes guide the
re-sedimentation process). Less and less sand travels to the “loss point” as
the beach grows and becomes progressively more efficient at holding
sand arriving from off shore sources (Figure 2). Over time, the natural beach
building cycle is restored (Figure 3).
