👉 Beach engineering, also known as coastal management or beach nourishment, is a set of techniques and strategies employed to combat coastal erosion and maintain or restore beaches. These methods involve the strategic placement of sand, sediment, or other materials onto eroding shorelines to counteract the natural processes of wave action and longshore drift that lead to beach loss. Techniques include direct sand placement, where large volumes of sand are dredged from offshore sources or inland deposits and deposited onto the beach; beach nourishment projects, which aim to replenish eroded beaches with new sand to widen them and enhance their protective capacity; and the construction of coastal structures like groins, breakwaters, and seawalls to stabilize shorelines. The goal is to preserve the beach's ecological balance, protect coastal infrastructure, and maintain recreational value while adapting to rising sea levels and climate change impacts.
