Projects To Limit Erosion Along Beaches And Coastlines

Most coastlines and beaches are today exposed to erosion. With a lot of the bottom vegetation gone, waves and sea currents will hit the water's edge with great power and create erosion.

• Projects to limit erosion on the water's edge:
  Grip erosion protection has been designed to reduce the powers of waves, currents and erosion. Lista Reef produces the same effect in shallow and unsheltered waters. The units are located underwater in a way to reduce the powers of waves and currents with a view to prevent damage to the bottom and water's edge. This solution has several positive side effects. The most important is that an accumulation of masses is produced between the units and the water's edge thus limiting erosion. Another positive side effect is that the units provide a habitat and sanctuary for fish and other marine life forms.
• Damage reduction in connection with high water level and tidal waves:
  A warmer climate may increase the water level with over 1 cm per year. Over time this may lead to heavy damages in many coastal areas. Grip erosion protection and Lista Reef may reduce the effects of waves and sea currents and limit damages from these.
• Avoid erosion and let pipe and cable lines become habitats for fish and other marine life forms:
  Svenner Reef prevents erosion and offers hiding places and habitats for fish and other marine life forms. In addition the products will protect and simplify installation and testing of pipes and cables close to land. It will not be necessary to excavate ditches and carry out covering operations with application of loose masses. Such operations may damage the marine biological environment for a long period.
• Avoid erosion and use rehabilitation projects for habitats for fish and other marine life forms:
  In several sea areas governments have had to implement rehabilitation projects to remove existing polluted bottom masses or have had to cover up with new clean masses. Both these operations will damage the marine biological environment and it may take several decades before a satisfactory new marine biological environment has been re-established. Through installation of artificial habitats the marine biological environment may be rehabilitated at an early stage. Loose masses will be exposed to erosion from the edges of these areas to the centers of them. It is therefore important to secure these edges with instruments such as Svenner Reef or Grip erosion protection to prevent erosion.
• 'Cofferdams' may reduce erosion and discharge of nutritional salts in brooks and rivers:
  The power of water currents will be reduced by placing Grip Reef in a curve across brook or river mouths. This will result in precipitation of eroded masses before they can be spread over a larger area and thus damage bottom environments of rivers, lakes and sea areas. The solution will enrich the marine biological environment and thereby increase the turnover of nutritional salts.
