Seadmevarustuse, also known as sea defense or coastal protection, refers to the measures and structures implemented to safeguard coastal areas from the erosive forces of the sea. These forces include wave action, currents, tides, and storm surges, which can lead to coastal erosion, flooding, and other forms of damage. Sea defense strategies are crucial for protecting human settlements, infrastructure, and natural habitats along the coast.

Common sea defense measures include seawalls, groynes, breakwaters, and beach nourishment. Seawalls are vertical structures built to absorb wave energy and prevent erosion. Groynes are long, narrow structures built perpendicular to the shore, designed to trap sediment and prevent it from moving along the coast. Breakwaters are offshore structures that reduce wave energy before it reaches the shore. Beach nourishment involves adding sand to beaches to replenish eroded areas and maintain their width.

The effectiveness of sea defense measures depends on various factors, including the type of coastline, wave conditions, and the specific needs of the area. For example, soft coastlines, characterized by sandy beaches, may benefit from beach nourishment, while hard coastlines, with rocky or cliffed shores, may require seawalls or groynes. Additionally, the success of sea defense measures can be influenced by climate change, which can alter wave patterns and sea levels.

Sea defense is a complex and multifaceted field that requires a balance between protecting coastal areas and preserving natural ecosystems. Sustainable sea defense practices aim to minimize environmental impact while providing effective protection. This often involves integrating natural solutions, such as mangroves and salt marshes, which can absorb wave energy and stabilize shorelines.
