meriseinät

Meriseinät is a term used in Finnish to describe sea walls or coastal defenses. These structures are built along shorelines to protect land from erosion, flooding, and the damaging effects of waves and storms. Meriseinät can vary significantly in design and construction, depending on factors such as the local environment, the severity of the threat, and the available resources.

Common materials used in the construction of meriseinät include concrete, stone, and gabions (wire cages filled with rocks). Some meriseinät are simple, low-lying barriers, while others are more complex, engineered systems designed to absorb or deflect wave energy. In some cases, natural elements like sand dunes or vegetation can also function as a form of meriseinä, providing a more environmentally integrated approach to coastal protection.

The purpose of meriseinät is crucial for coastal communities, protecting infrastructure, homes, and valuable land from the destructive forces of the sea. They play a vital role in mitigating the risks associated with rising sea levels and increasingly severe weather events. The design and maintenance of effective meriseinät are ongoing considerations for coastal management and planning.
