Sandy beaches are limited natural resources that provide valuable real estate, recreation, and billions of dollars in annual tourist revenues worldwide. The loss of beaches due to erosion can have significant economic impacts, and new strategies are continuously being implemented in an attempt to mitigate the effects of coastal erosion.

Coastal erosion can be caused by many factors, including wave activity and storm events. Measures to combat erosion usually fall in to one of two categories: 1.) “Hard” structures such as sea walls, groynes, jetties, breakwaters, etc., and 2.) “Soft” approaches such as ‘beach nourishment’, which is the placement of new sand on an eroded beach. The practice of beach nourishment has been used for many years and is considered a useful approach to combating erosion; however, it is well documented that beach nourishment is only a temporary fix to a perpetual problem. In fact, nourished beaches often erode 2-3 times faster than unnourished beaches. As a result, beach nourishment projects are usually scheduled every 3-5 years as a general maintenance plan and often cost millions of dollars.

One of the difficulties in executing a successful beach nourishment project is the identification and procurement of compatible sand. All sand is not created equal, and adding incompatible sand to a beach can have detrimental effects that range from increasing the propensity for erosion to creating a habitat that is no longer suitable for marine life such as nesting sea turtles.

With this in mind, the founders of Hydros Coastal Solutions, Inc. focused their research efforts on a way to protect beaches and promote sand accretion in an environmentally friendly, natural way by capitalizing on the significant abundance of sand usually located directly offshore. Their proprietary technology, ShoreLockTM, works by creating an environment that promotes the interaction of sand with water molecules. When sand re-establishes its natural cohesion, the result is a natural, retained accretion as currents and wave activity bring in offshore sand.

HCS in an innovative, forward thinking group of scientists and businessmen that focus entirely on green alternatives to environmental restoration. All of Hydros Coastal’s products, including ShoreLockTM, are completely non-toxic and are made entirely from USFDA “GRAS” (Generally Regarded as Safe) Ingredients.

To date, HCS has completed two successful projects in the Turks and Caicos and the Bahamas. As can be seen in Figure 1, both beaches were improved drastically without the addition of any trucked in or dredged sand.

About Hydros Coastal Solutions, Inc.

Hydros Coastal Solutions, Inc. is a conglomerate of scientists and businessmen working together to reshape and re-nourish the world’s coastlines with natural, sustainable, and eco-friendly methods. Our proprietary technology, ShoreLockTM, is a novel alternative or complement to current methods of coastal restoration because it offers a non-intrusive, scientifically engineered, and eco-friendly solution that promotes sand cohesion and sustainable coastal stability.

Comparison of ShoreLockTM Technology to Traditional Methods of Coastal Restoration

The benefits of our unique approach to coastal remediation are presented below. For comparison purposes, we have highlighted the potential shortcomings of “conventional” nourishment practices. We acknowledge that conventional approaches are neither universally detrimental nor ineffective and we promote the utility of using our novel approach along with conventional methods to achieve synergistic results.

GREEN:

  • The Hydros Coastal SolutionTM – 100% Non Toxic. All of our products are considered USFDA GRAS (Generally Recognized as Safe).
  • Conventional – Dredging and dumping operations may bury benthic organisms under tons of foreign or dredged sand. Dredging operations may disrupt the sea floor by destroying the ecology, dislodging pollutants, and increasing turbidity in surrounding areas.

SUSTAINABLE:

  • The Hydros Coastal SolutionTM – Our treated beaches have been shown to withstand severe storm conditions and hurricane force winds.
  • Conventional – Nourished beaches are often not stable in storm conditions and typically erode as a result of significant storm activity.

MAINTENANCE:

  • The Hydros Coastal SolutionTM – Sustained through minor, cost-effective reapplications.
  • Conventional – Renourished beaches are left no more “stable” than they were prior to sand application. Traditional nourishments are usually scheduled every 3-5 years.

AESTHETICS:

  • The Hydros Coastal SolutionTM – No permanent structures and no heavy equipment.
  • Conventional – Typically involves structures (groynes, breakwaters) or heavy equipment, which is intrusive to the beach community.

WATER QUALITY:

  • The Hydros Coastal SolutionTM – Ocean clarity increases next to the treated coastline as turbidity decreases.
  • Conventional – Ocean floor disturbance dislodges silt and greatly increases turbidity for large areas surrounding a dredging operation. Silt poses a dangerous and sometimes toxic condition for surrounding ecosystems.

RESULTS:

  • The Hydros Coastal SolutionTM – Treated beaches exhibit clean, moist, fine sand particles. Beach levels rise, the high tide watermark is pushed seaward, offshore erosion trenches are filled, and water clarity improves.
  • Conventional – Conventional methods of beach nourishment are usually effective in the short term. However, it is becoming increasingly difficult to source compatible sand for conventional nourishment projects.
