Sand fences are barriers constructed from wooden slats, wire mesh, or geotextile fabric that are installed perpendicular to the prevailing wind direction to trap and accumulate windblown sand, thereby forming dunes. These fences are widely used in coastal areas to prevent erosion, protect infrastructure, and create new land.
Sand fences are instrumental in combating coastal erosion, a significant issue in many parts of the world. By trapping sand and promoting dune formation, they help to stabilize the shoreline and reduce the impact of waves and storm surges. Additionally, sand fences provide important habitat for various plant and animal species, contributing to the ecological balance of coastal ecosystems. The practice of using sand fences dates back centuries, with early examples found in the Netherlands and France.
